ArcGIS includes client software, server software, and data components. ArcGIS itself is not a GIS application; rather, it is a system of software products, each servicing a specific need. Software products and applications When someone purchases an ArcGIS system, they license software products which include one or more software applications. Understanding the difference between products and applications is important in understanding how ArcGIS is structured, and how the topics covered in this training class relate to the system as a whole. For example, one group may license the ArcView software product, which includes the ArcMap, ArcCatalog, and ArcToolbox applications. Another group may license the ArcEditor software product, which includes the same three applications. After installing their respective products, both groups would find icons for the ArcMap, ArcCatalog, and ArcToolbox applications in their Start menus; neither would find an ArcView or ArcEditor icon. But upon running the applications, the ArcEditor group would find more button and menu choices than the ArcView group. In another example, a group who licenses the ArcSDE software product may install and use the ArcSDE, ArcSDE CAD Client, and ArcSDE for Coverages applications.

Extensiones de ArcGIS Extensiones que se incorporan en nuevas aplicaciones 3D Analyst ArcPress ArcScan Geostatistical Analyst Publisher Spatial Analyst StreetMap Survey Analyst Tracking Analyst ArcGIS extensions There are a number of software extensions that work in conjunction with ArcView, ArcEditor and ArcInfo. These extensions have been created for specific types of applications and analysis. Most extensions are a separate and additional purchase that supplement your current ArcGIS application. 3D Analyst is used for creating, analyzing, and displaying surface data. ArcPress is a PostScript-based Raster Image Processor (RIP) that prints and exports maps. ArcScan is a powerful tool set for importing, correcting, editing, plotting, and exporting scanned raster images. Geostatistical Analyst will allow you to use kriging and other advanced mathematical methods used in the analysis of spatial properties. Publisher allows you to save maps for distribution and sharing with others. Publisher converts ArcMap map documents (.mxd) into the published map format (.pmf) used with ArcReader. Spatial Analyst was created for complex analysis with raster data and to perform integrated vector-raster analysis. StreetMap is an extension product that supports nationwide address geocoding and street map display. Survey Analyst manages survey data and represents survey measurements and observations on a map. Tracking analyst is an extension for mapping objects that move or change status through time. To load an ArcGIS extension for use in ArcMap, click Extensions from the Tools menu and select the extension or extensions you want to use. Each extension will have a specific toolbar for your use. To activate the toolbar, right-click on the ArcMap interface and select the extension’s toolbar from the context menu. Introduction to ArcGIS for ArcView and ArcInfo (II)

Trabajando con datos geográficos
Dibujo, búsqueda, análisis Geometría Atributos Validación Components of geographic data There are three general components to geographic information: Geometry represents the geographic features associated with real-world locations. Geographic features are abstracted into points, lines, or areas. Attributes provide descriptive characteristics of the geographic features. Validation means that geographic features can be made to allow certain types of editing, display, or analysis, depending on circumstances that the user defines. Feature validation is most easily implemented in the geodatabase. Introduction to ArcGIS for ArcView and ArcInfo (II)

Almacenando datos geográficos
Dos estructuras comúnes: Vector y Raster Se utiliza la extensión Spatial Analyst para el análisis de datos raster Realidad Vector (puntos, lineas y polígonos) Raster (celdas) Spatial data structures In general, there are two structures into which you can abstract the real-world: vector and raster. Vector structures In a vector data model, each point is recorded as a single x,y coordinate. Lines are recorded as a series of x,y coordinate pairs. Areas are recorded as a series of x,y coordinate pairs defining line segments that enclose an area; therefore, the term polygon, meaning ‘many-sided figure’. Areas have a perimeter and lines have a length. Examples of vector data are ArcInfo coverages and ArcView shapefiles. ArcGIS is well suited for performing analysis with vector datasets. You can perform standard GIS tasks such as feature display, manipulation, and analysis. Raster structures In the raster data model, the earth is treated as one continuous surface, and each location is represented as a cell. Cell values are used to represent a geographic phenomenon. Cells are organized into a matrix of rows and columns called a grid. Cell values are numbers, and can represent discrete data such as land-use classes, or continuous data such as elevation values. The ArcGIS Spatial Analyst extension stores grid themes as directories in the ARC GRID™ format. This format is the cell-based equivalent of an ArcInfo coverage. If you do not have the Spatial Analyst extension, your grid themes will be treated as images and can be used for display only. Introduction to ArcGIS for ArcView and ArcInfo (II)

Formatos de datos espaciales ArcGIS
Los tipos de datos varian dependiendo de su complejidad Se ajusta a distintas características de modelos Coverage Geodatabase Shapefile CAD Grid Tin Table Internet Map Service Spatial data formats The ArcGIS applications support a wide range of spatial data formats, allowing you a great deal of flexibility in the data you may use. Each spatial storage format has strengths and limitations, and you can choose the format that best suits your needs. Features stored together with the same type of geometry: point, line, or polygon, are referred to as a feature class. In addition to the same geometry types, a feature class uses the same attribute columns to describe all of its features, and all features share the same spatial reference. Depending on the storage format, feature classes with spatial relationships between them may be grouped together in a feature dataset. This class focuses mainly on the vector data formats of shapefiles, coverages, and geodatabases for modeling spatial features. Introduction to ArcGIS for ArcView and ArcInfo (II)

Feature behavior is most easily implemented in the geodatabase. In the geodatabase, you can set two types of validations: Spatial and attribute. Spatial validation Spatial validation can be used in two ways: Topology or Geometric Networks. Both of these spatial validation types require a feature dataset where dedicated feature classes participate in either the Topology rules or the Geometric Network rules. A single feature class cannot participate in both. Both of these spatial validation are available in ArcEditor and ArcInfo Attribute validation Attribute validation are of three types: Subtypes, Domains, and Relationship classes. These types of validations are necessarily used with tabular data. Both of these validations are required for maintaining data integrity and efficiency during management, display, and editing operations on the geodatabase. Feature classes Feature classes can be placed in a geodatabase either as standalone or under a feature dataset. Feature classes can contain either points, lines, or polygons. Feature datasets Feature datasets are important for maintaining feature classes that are topologically related. Both topology and relationship classes can only be created in a feature dataset.

Utilizando el ArcCatalog
Proporciona una vista uniforme de sus datos Definir o modificar tablas y definiciones de feature class Administrando datos: Copiar, Renombrar, Borrar Using ArcCatalog ArcCatalog is the application where you can assemble connections to all the data you need to use. When you select a connection, you can access the data to which it is linked to, whether it is located on a local disk or a database on the network. Together, your connections create a catalog of geographic data sources. You can browse your data holdings in three different ways in ArcCatalog using three different tabs: the Contents tab, the Preview tab, and the Metadata tab. The Contents tab shows what a selected item—perhaps a folder or database file—contains. The Preview tab will give a preview of the selected item’s geographic or tabular data. The Metadata tab will show the metadata for a selected item. Within ArcCatalog you can move, copy, rename, and delete geographic data, and create, manage, and edit associated metadata. You can also perform some modifications to the data, such as adding fields to tables, defining subtypes, domains, and table relationships. Introduction to ArcGIS for ArcView and ArcInfo (II)

Añadiendo tablas de las fuentes existentes
Acceso directo para Info, dBASE, y textos delimitados por comas Acceso a datos remotos Conexión OLE DB Accessing existing databases You may access existing Info, dBASE or comma delimited text files simply by connecting to the folder that holds them. To access tabular data in other formats, you can use Object Linking and Embedding Database (OLE DB) providers. ArcCatalog communicates through an OLE DB provider which then communicates with a different database. This standard lets you work with data from any database in the Catalog in the same way. Looking in an OLE DB connection in the Catalog, you will see a list of tables in the database. Microsoft’s OLE DB providers come with ArcCatalog. They let you access Jet (Microsoft Access), SQL Server, and Oracle databases. Another provider communicates with Open Database Communication (ODBC) drivers. Introduction to ArcGIS for ArcView and ArcInfo (II)

Ajustando la visualización de datos
Encender o apagar todo tipo de datos Setting viewable data You can control what appears in the Catalog tree of ArcCatalog. This can be done by clicking the Tools menu and selecting Options. Within the Options window and in the General tab, you have the choice of deciding which data types to turn on or off. Turning a data type off will result in the data type to not to be listed in the Catalog tree of ArcCatalog. In other words, to ArcCatalog, the data type becomes invisible, unreadable, or both. Introduction to ArcGIS for ArcView and ArcInfo (II)

Administrando tipos de archivos visibles en ArcCatalog
Añadir macros AML, archivos de texto, otros archivos 3 4 1 2 5 Managing file types visible in ArcCatalog By default, not all file types are set to be displayed in the Catalog tree of ArcCatalog. Only the most common types of data are visible in ArcCatalog. In order to enable other file types to be listed in the Catalog tree of ArcCatalog, click the Tools menu, and select Options. Within the Options window, click the File Types tab, then select New Type. In the File Type window, type the file extension of the data type that you want to add (e.g., AML), in the input field. Then complete the Description of Type (e.g., Arc Macro Language for AML) input parameter and click OK. This will add the information about this file type in the Options menu, such that when you exit the menu, all available .aml files that are contained in the database will be listed in the Catalog tree. You can repeat this procedure for other file types, such as text files (.txt), exchange files (.e00), and so on. Introduction to ArcGIS for ArcView and ArcInfo (II)

Opciones de contenido Desplegar más metadatos
en la ventana de contenido Columnas Standard Columnas de Metadatos Contents options When you start using ArcCatalog, you will see two columns in Details view that show the Name and Type of each item. You can add columns that show additional properties or information stored in the item's metadata. When an individual item is selected in the Catalog tree, the values that would appear for that item in all columns in Details view are listed in the Contents tab. A column may not apply to all items. You can add your own property and metadata columns to the lists in the Options dialog box. To do so, you must type the exact name of the property or metadata element into the Property text box in the Add Standard Column or Add Metadata Column dialog box. The columns that are included in these lists by default appear in the Caption and Property lists in the dialog boxes. If you delete default columns, you can easily add them again later by choosing their caption or name from either the Caption or Property dropdown lists.

Selección de color de columna Texto font, color, tamaño
Opciones de tablas Modificando la apariencia de una tabla Comportamiento Selección de color de columna Texto font, color, tamaño Tables options You can change the appearance of tables in the Catalog to make it easier to read their values. For example, you may want to change the size, color, and type of font used. To quickly pick out which columns are selected, the background color of selected columns is set to the highlight color. When you see an asterisk (*) next to a column’s name, the values in that column are indexed; indexes can improve the performance of queries. Use the Options dialog box to change the font, highlight color, and index character used in Table view to suit your preferences. These changes affect the way all tables appear in the Catalog.

Opciones por defecto de arreglo de bandas
Opciones Raster Opciones por defecto de arreglo de bandas Calculo de piramides Formatos de imagenes a buscar Para grids e imagenes Piramides Copias para reducir la resolución y desplegar las imagenes más rapidamente Raster options You can also control the way raster data is displayed in the Catalog tree and in the display area of ArcCatalog. To access the raster data display properties, click the Tools menu, and click Options. Within the Options window, click the Raster tab. This tab allows you to control the display of both grids and images. You can set the Default RGB Band Combinations depending on the number of bands you have in the source data. You can also assign which band will be displayed by any of the three standard Red, Green, and Blue guns. This combination will dictate the type of false color imagery you are trying to set to help in interpreting the imagery (especially for satellite images). By default, for a three-band data source, band one will be assigned to the Red gun, band two the Green gun, and band three the Blue gun. The default assignment for a data source with four or more bands is: band four (near-infrared reflectance) to the Red gun, band three (red reflectance) the Green gun, and band two (green reflectance) for the Blue gun. Raster data requires a long time to display, especially if it is of high resolution. You can use the Raster Layer Pyramid Calculation option (on the Raster tab) to display the images with reduced resolution (i.e., you can generalize the raster data for faster displays). You can also control which raster file formats will be listed in the Catalog tree of ArcCatalog on the Raster tab. Introduction to ArcGIS for ArcView and ArcInfo (II)

Buscando datos Buscar por Resultados Nombre y localización Geografia
Fecha Metadatos Resultados Localizado en el árbol de Catalog Atajos para apuntar al dato Puede ser utilizado en cualquier lugar en donde se utilicen los datos Searching for data You can use the Search tool in ArcCatalog to search for data meeting a specific criteria: name and location, geography, date, or an entry in the metadata. Once you click Find Now in the Search dialog box, shortcuts to those items that match the search are added to a list in the Search Results folder in the Catalog tree. These shortcuts provide a link to that matching item wherever it is stored. When a shortcut is selected in the Catalog tree, you can preview the item’s data and metadata in the appropriate tabs as if you were exploring the contents of the item itself. Once you have found the item that you want to use, you can right-click the shortcut and click Go To Target to select the item itself in the Catalog tree. Alternatively, you can work with the shortcut as if you were working with the item itself. You can drag-and-drop a shortcut onto a map or an ArcToolbox tool. You can also double-click a shortcut to open the item’s Properties dialog box. Introduction to ArcGIS for ArcView and ArcInfo (II)

You can use rulers, guides, and grids to align map elements on the ‘virtual’ page you use in Layout View. The Layout View Options let you control how these design elements perform. Rulers show the size of the page and map elements of the final printed map. Guides are straight lines that you use to align map elements on the page. A Grid is a series of reference point on the layout page that you use to position map elements. You can choose to turn on or off snapping to any or all of these alignment features.

For example, you might change the text size and font so that it makes a greater visual impact or is easier to read. You might also want to change the shape of the lines and patches that represent the features on a map. The Table of Contents has two default tabs at the bottom: a Display tab and a Source tab. The Display tab shows the drawing order of the layers and allows you to change the order. The Source tab sorts layers by where they are stored on disk, it is also the tab you use if you want to view any non-spatial tables you have added to your map (e.g., DBF or INFO). This is useful during editing, when you edit all layers in a given folder or database. If you are not planning on using your map for editing, you can hide the Source tab. You cannot change the drawing order of layers from the Source tab. Additionally you have a Selection tab which you can activate in the Table of Contents. This will allow for an alternative method of changing the selectable layers while editing. Introduction to ArcGIS for ArcView and ArcInfo (II)

Creando despliegues cuantitativos
Símbolos graduados Color graduado Atributos multiples 1 Dot = 50 people Densidad de puntos Gráficos Símbolo proporcional El uso de despliegue cuantitativos utiliza un esquema de clasificación Creating Quantitative Displays Quantitative data is data that describes features in terms of a quantitative value measuring some magnitude of the feature. Unlike categorical data, where features are described by a unique attribute value such as a name, quantitative data generally describes counts or amounts, ratios, or ranked values. For example, data representing precipitation, population, and habitat suitability can all be mapped quantitatively. Which quantitative value should you map? Knowing what type of data you have and what you want to show will help you determine what quantitative value to map. In general, you can follow these guidelines: Map counts or amounts if you want to see actual measured values as well as relative magnitude. Use care when mapping counts as the values may be influenced by other factors and could yield a misleading map. For example, when making a map showing the total sales figures of a product by state, the total sales figure is likely to reflect the differences in population among the states. Map ratios if you want to minimize differences based on the size of areas or numbers of features in each area. Ratios are created by dividing two data values and are also referred to as normalizing the data. For example, dividing the 18- to 30-year-old population by the total population yields the percentage of people aged Similarly, dividing a value by the area of the feature yields a value per unit area, or density. Map ranks if you are interested in relative measures and actual values are not important. For example, you may know a feature with a rank of 3 is higher than one ranked 2 and lower than a 4, but you cannot tell how much higher or lower. Introduction to ArcGIS for ArcView and ArcInfo (II)

Escogiendo un método de clasificación
Clasificación de los atributos en grupos Seis métodos de clasificación Quiebres naturales (por omisión) Manual Intervalos iguales Intervalos definidos Quantiles Desviación estándard Choosing a classification method When you map quantitative data, you can either assign each value its own symbol or group values into classes using a different symbol for each class. If you are only mapping a few values (less than 10), you can assign a unique symbol to each value. This may present a more accurate picture of the data, because you are not predetermining which features are grouped together. More likely, your data values will be too numerous to map individually and you will want to group them in classes, or classify the data. A good example of classified data is a temperature map you might find in a newspaper. Instead of displaying individual temperatures, these maps show temperature bands, where each band represents a given range in temperature. Ways to classify your data How you define the class ranges and breaks (the high and low values that bracket each class) will determine which features fall into each class and thus what the map will look like. By changing the classes you can create very different-looking maps. Generally, the goal is to make sure features with similar values are in the same class. Two key factors for classifying your data are the classification scheme you use and the number of classes you create. If you know your data well, you can manually define your own classes. Alternatively, you can let ArcMap classify your data using standard classification schemes. The four most common schemes are natural breaks, quantile, equal interval, and standard deviation. These are described on the following pages. Introduction to ArcGIS for ArcView and ArcInfo (II)

Utilizando los quiebres naturales
Método por defecto Identifica quiebres entre los valores Muestra agrupaciones o concentración de valores Using natural breaks Classes are based on natural clusters of data values. ArcMap identifies break lines by looking for groupings and patterns inherent in the data. The features are divided into classes whose boundaries are set where there are relative gaps in the data values. Introduction to ArcGIS for ArcView and ArcInfo (II)

Utilizando quantiles o intervalos iguales
Cada clase contiene el mismo numero de elementos Divide los valores en dos rangos iguales Using quantile and equal interval In a quantile classification, each class contains an equal number of features. A quantile classification is well suited to linearly distributed data. Because features are grouped by the number in each class, the resulting map can be misleading. Similar features can be placed in adjacent classes, or features with widely different values can be put in the same class. You can minimize this distortion by increasing the number of classes. The equal interval classification scheme divides the range of attribute values into equal-sized subranges. For example, if features have attribute values ranging from 0 to 300 and you have three classes, each class represents a range of 100 with class ranges of 0-100, , and This method emphasizes the amount of an attribute value relative to other values, for example, to show that a store is part of the group of stores that made up the top one-third of all sales. It is best applied to familiar data ranges such as percentages and temperature. Introduction to ArcGIS for ArcView and ArcInfo (II)

Utilizando la desviación estándard
Muestra la distribución sobre y bajo el promedio 4 1 3 2 260 807 1,354 1,900 2,447 493 947 1,400 1,853 2,307 Promedio = 1,173 -1 +1 +2 +3 -2 Desviación estándard = 453 Using standard deviation This classification scheme shows you the amount a feature’s attribute value varies from the mean. ArcMap calculates the mean value and then generates class breaks by successively adding to it or subtracting from it the standard deviation. A two-color ramp helps emphasize values above (shown in blue) and below (shown in red) the mean. Introduction to ArcGIS for ArcView and ArcInfo (II)

Excluyendo características de una clasificación
Elimina valores que interfieren en la clasificación Excluding features from a classification It is always a good idea to examine your data before you map it. For instance, you may find that you have a few extremely high or low values or null values where no data is available. These values can skew a classification and thus the patterns on the map. Fortunately, you can choose to exclude these values before you classify your data. Introduction to ArcGIS for ArcView and ArcInfo (II)

Estandarizando los datos
Divide un atributo por otro para determinar una relación Densidad de población Total de ventas por área Normalizing your data You may also want to normalize your data before you map it. When you normalize data, you divide it by another attribute to come up with a ratio. Often, ratios are easier to understand than the raw data values. For example, dividing total population by area yields the number of people per unit area, or a density. Dividing a store’s sales figure by the total sales for all stores yields a percentage of sales at that store. A Introduction to ArcGIS for ArcView and ArcInfo (II)

Símbolos graduados y proporcionales
El tamaño del símbolo refleja la clasificación El tamaño del símbolo refleja el valor actual del dato Graduated and proportional symbols When you draw features with graduated symbols, the quantitative values are grouped into classes. Within a class, all features are drawn with the same symbol. Thus, you cannot discern the value of individual features; you can only tell that its value is within a certain range. Proportional symbols represent data values more precisely. The size of a proportional symbol reflects the actual data value. For example, you might map earthquakes using proportional circles, where the radius of the circle is based on the magnitude of the quake. The difficulty with proportional symbols arises when you have too many values; the symbols may become indistinguishable. Also, the symbols for high values can become so large as to obscure each other. Introduction to ArcGIS for ArcView and ArcInfo (II)

Mostrando cantidades por medio de concentración de puntos
Determine el tamaño del punto y su valor Apto para áreas de altas y bajas concentraciones Showing quantity with dot density When creating a dot density map, you specify how many features each dot represents and how big the dots are. You may need to try several combinations of amount and size to see which one best shows the pattern. In general, you should select values that ensure the dots are not so close as to form solid areas that obscure the patterns, or so far apart as to make the variations in density hard to see. Introduction to ArcGIS for ArcView and ArcInfo (II)

Desplegando multiples atributos
Simbolizando carácteristicas basándose en más de un atributo Tipo de calle y volumen de tráfico vehicular Uso de la tierra y valor Displaying multiple attributes Geographic data usually has a number of different attributes that describe the features it contains. While you will commonly use one of the attributes to symbolize the data (e.g., show categories or quantities), you may sometimes want to use more than one. For example, you might display a road network using two attributes: one representing the type of road and the other representing the traffic volume along it. In this case, you could use different line colors to represent the different types of roads and also vary the line width to indicate traffic volume along each road. When you symbolize your data using more than one attribute, you create a multivariate display. Symbolizing your data this way can effectively display more information about the data; however, it can also make your map more difficult to interpret. Sometimes it might be better to create two separate displays than to try to display the information together. Introduction to ArcGIS for ArcView and ArcInfo (II)

Templates can contain data, a custom interface, and a predefined layout that arranges map elements, such as North arrows, scale bars, legends, and logos, on the virtual page. They are especially useful when many maps with the same design need to be created. Templates can contain scripts that you might have written on how to structure your layout or certain layers that you want to appear in all your maps. Map templates have an .mxt file extension. You can store your template permanently under the templates folder in either ArcGIS templates: Arcexe83\Bin\Templates (server install), or For Windows NT: C:\Winnt\Profiles\<user>\Application Data\Esri\ArcMap\Templates or For Windows 2000: C:\Documents and Settings\<user>\Application Data\Esri\ArcMap\Templates When you are storing a layout as a map document, make sure you store it with an *.mxd extension.

Exportando un mapa Exportandolo a una imágen Exporting a map
Once you have created a map, you may want to export it from a map document to an image file. The new image could then be inserted into another document (for example, Microsoft Word or PowerPoint). Export a map by choosing Export Map from the File menu. You can export maps as several types of image files. Some of these include EMF, BMP, EPS, PDF, and JPEG. EMF (Enhanced Metafiles) are Windows native vector, or vector and raster graphics. They are useful for embedding in Windows documents because they can be resized without distortion. BMP (bitmap) files are simple, native Windows raster images. They do not scale as well as EMF files. EPS (Encapsulated PostScript) files are primarily used for vector graphics and printing. PDF (Portable Document Format) files are designed to be consistently viewable across different platforms. They are commonly used for distributing documents on the Web. JPEG (Joint Photographic Experts Group) files are compressed image files. They are commonly used for images on the Web because they are more compact than many other file types.

A large part of this lesson focuses on setting labeling properties. Once the labels are symbolized and positioned correctly, you can convert the labels to annotation. Annotation is stored in the geodatabase as features that can be manipulated in an edit session. Annotation can also be created from scratch or imported from a coverage. The following topics will be discussed: Labeling options Label placement Label visibility Grouping labels Generating annotation Introduction to ArcGIS for ArcView and ArcInfo (II)

Despliegue en línea Se almacenan como una propiedad de la capa Etiquetas Anotaciones Guardadas como un elemento Se almacen separadamente de la clase de elemento de origen Capa de gráficos Geodatabase Labeling options You have two feature labeling options on your map: labels or annotation. Labels A label is text that displays dynamically on your map document. When you zoom and pan around your map, the labels re-display themselves with the best placement for the scale at which you are viewing the map. Label placement is based on the properties set up for the layer. Because the labeling properties are a property of the layer, they will travel with the layer whether it is stored in a map document or a layer file. Annotation Unlike labels, annotations can be treated individually regardless of where they are stored. Labels let you set properties that affect the symbology and placement of all the labels on your map, but you cannot change the properties for a single label. However, you can manually change the properties for a single annotation. The annotation size also stays constant relative to the other features on the map. For example, when you zoom out on a feature, that feature will appear smaller on your screen. Because annotation is just another type of feature, when you zoom in and out on annotation, it will act the same as the other features on your map. Labels, on the other hand, will always remain the same point size regardless of your scale. Annotation can be stored as a graphic on the map or as a feature in the geodatabase.

Each position is given a number to indicate its priority: 0, 1, 2, or 3 (1 being the highest and 3 being the lowest). The software will try to place the label starting with the highest priority position (1) and finish with the lowest priority (3). A position with a value of 0 means that that position is off limits and no label will be placed at that position. Place label on point Labeling on the point means that the label is centered on top of the point. Hierarchy of angles Labeling with specified angles allows you to specify a hierarchy of angles around a point where labels will be placed. The angles start at 0, which is to the right of the point, and continue in a counter-clockwise direction. Conflict detection rules are available for all the label placement options. Weights between labels and features Weights can be set for the labels and features. Objects assigned a high weight will not be obstructed and given priority above other objects in the same layer and other layers in the display. Buffer ratio A buffer ratio is the amount of space reserved around the label. You can use the buffer ratio to ensure labels are not placed too close to other labels or features.

Impuesta Basada en la orientación Posición en una línea Al inicio o al final A lo largo Desplazado en Unidades de mapa Angulo La etiqueta puede seguir la trayectoria de la curva Al final Abajo y a la izquierda Arriba y a la derecha Siguiendo la trayectoria de la curva Line placement Label placement for a line is first based on whether the label is oriented to the page or to the line. If the label is line-oriented, it can be placed to the left or to the right of the line based on the line’s direction. You can determine a line’s direction by symbolizing it with one of the arrow options, which are located at the bottom of the symbology list. If your label orientation is based on the page, your labels can be placed above or below the line. There is also an option for ignoring orientation and placing the label on top of the line. Line labels can also be placed at the beginning of a line, at the end of a line, or best-fit along a line. You can make the text curve parallel to the curvature of the line. An offset between the label and the line, in map units, can be applied for more aesthetic calligraphy. In addition, you can also control the angle of the text relative to the line, i.e., along the line, horizontal, or vertical. Introduction to ArcGIS for ArcView and ArcInfo (II)

If you zoom in on your map and a layer appears (i.e., the features in the layer appear), the labels for that layer will appear as well. Alternatively, you can choose to set a scale range for the labels independent of the features in the layer. For example, imagine you are zooming in on a city. When you reach a scale of 1:24,000 the streets appear, but the labels do not. However, when you reach 1:12,000, the labels for the streets appear. Introduction to ArcGIS for ArcView and ArcInfo (II)

Visual Basic Script ó JavaScript Concatenación simple + JavaScript & Visual Basic Script Expresiones lógicas Click Avanzado If...Then New line ‘\n’ JavaScript ‘vbNewLine’ Visual Basic Script [Name] & vbNewLine & [POPULATION] Labeling with an expression By default, labels consist of single field values. You can also label features with an expression built using Visual Basic Script or JavaScript. You can use an expression to label with multiple fields in a concatenated format, and further format those fields with descriptive text. Concatenation is done using specific characters. For Java scripts, use the + sign for concatenation and for Visual Basic scripts use the & sign for concatenation. Logical expressions can also be used to set conditions for labeling the same features differently. For example, you might label capital cities with their names and populations, but label all other cities with just their names. Logical expressions can be syntaxed with If … Then statements. While concatenating you may want to stack the information that comes from the different fields. This can be done as follows depending which programming language you are using. ‘\n’ JavaScript Use ‘\n’ for stacking when writing Java scripts for your logical expression. “vbNewLine” Visual Basic Script Use ‘vbNewLine’ for stacking when writing Visual Basic scripts for your logical expression.

These options let you create groups of features that are labeled differently with classes. A class represents a group of features with the same labeling properties. The group of features represented by a class is defined with a SQL expression. All the labeling properties discussed up to this point in the lesson also apply to a class. With classes, you can change labeling properties for different groups of features. For example, if you labeled capital cities with larger text than the other cities, you would have a class representing the capitals and a class representing the other cities. The group of features represented by a class is defined with a SQL expression. This option can be accessed by clicking the SQL Query button. Introduction to ArcGIS for ArcView and ArcInfo (II)

Ajustando la escala de referencia
Para un data frame El texto se escala con los elementos del mapa Acercamiento sin escala de referencia definida Acercamiento con una escala de referencia definida Define la escala de referencia Setting reference scale Setting the reference scale lets you fix the size of the labels relative to the other features in the map at a specific scale. When you set the reference scale, the labels will remain at their current size in map units. The reference scale is set to control the entire data frame. Once the reference scale is set, the text appears larger when you zoom in and smaller as you zoom out. When the reference scale is not set, the point size is maintained as you zoom in and out so that labels appear to be the same size relative to your screen Setting the reference scale is a preparatory step for creating annotation from your labels. Annotation features have a reference scale built into their data structures; when you add annotation to your map, you do not need to set the reference scale because those features will already have a reference scale. Determining the correct reference scale for your labels is useful when you create annotation from those labels, because you will know how the annotation will appear at certain scales.

To assign each piece of text to a specific location, you must convert your labels to annotation. Remember that annotation stores its own reference scale. When you create annotation, the current scale will be used as the reference scale for this annotation. This can be confusing if you are zoomed out to the full extent or if you are zoomed in on the map; your annotation may not turn out the way you expect. Before converting to annotation, set the reference scale for your labels and make sure they display the way you want them to appear. In addition to converting your labels to annotation, you can create a new annotation feature class in ArcCatalog. After creating the annotation feature class, add the new annotation features to that feature class. Then the annotation will be feature linked. You can then add these new annotation features individually with the Text tool while you are editing a map. You can also load the annotation from a coverage. The coverage annotation is treated like labels that are being converted to annotation. The new annotation will include a reference scale that you set when you create that annotation feature class in ArcCatalog. You can add these new annotation features using the Convert Coverage Annotation tool in the Label category of the Customize dialog box. Introduction to ArcGIS for ArcView and ArcInfo (II)

In a graphics layer: The annotation graphics are stored in a graphics layer in your map. You would store annotation in a graphics layer if this annotation is only applicable to that particular map. This could make the size of your map very large, but if you give this map to someone else, the annotation will automatically come with the map. As geodatabase feature: This stores your annotation in the geodatabase as features that are not related to any other features. If you move the features denoted by this annotation, the annotation does not move. Also, if you change the text in the field that generated the annotation, the annotation is not affected. You would store unlinked annotation if you want your annotation to be a historic record of a specific time. For example, perhaps your annotation represents the names of the streets in In this case, you would not want the annotation to update when the feature updates because you would want it to store the names for that feature as it was at a specific time. As feature-linked geodatabase features: This stores your annotation in the geodatabase with a relationship to the features that the annotation was created from. When you move the original feature, the annotation moves with it, and when you update the text value that the annotation is created from, the annotation text automatically updates. You would use linked annotation when you want your annotation to reflect the current state of your features. 7646 Introduction to ArcGIS for ArcView and ArcInfo (II)

¿Qué es la Geocodificación?
Asocia una dirección a una localización geográfica Las direcciones se asocian a rangos de direcciones sobre los datos de carreteras Una localización en el mundo real es asignada a cada dirección What is geocoding? A feature is an object that has geometry. In most cases, this geometry is captured by digitizing or scanning paper maps. In many cases, however, geographic data exists that indirectly captures geometry by describing locations such as street addresses, city names, or even telephone numbers. While you understand what these descriptions mean and how they relate to locations on the earth’s surface, computers do not. In order to display these locations on a map and perform analysis with them, a computer must be given geometric representations (such as point features) of these locations. Geocoding, also known as address matching, is the process of creating geometric representations for descriptions of locations. A geocoding service defines the process for converting these descriptions into geometric shapes. You can use a geocoding service to find individual addresses and to geocode tables of addresses. You can also review and rematch the feature classes and shapefiles that you create through geocoding. Introduction to ArcGIS for ArcView and ArcInfo (II)

Crear un servicio de geocodificación en ArcCatalog Define como se encontrará la dirección Añadir el servicio de geocodificación a un mapa Correspondencia de direcciones Direcciones individuales Direcciones almacenadas en una tabla Reasigna las direcciones no asignadas The geocoding process The first step in the geocoding process is to create a geocoding service in ArcCatalog. Geocoding services use a specific set of steps to find a match for an address. First, the geocoding service standardizes the address. Second, the geocoding service searches the geocoding reference data to find potential candidates. Next, each potential candidate is assigned a score based on how closely it matches the address. Finally, the address is matched to the candidate with the best score. Once you have added a geocoding service to an ArcMap document, you can begin geocoding addresses with it. You can geocode a whole table of addresses or use the Find tool to search for individual addresses. After you have geocoded a table of addresses, you will want to review the results. If you are unhappy with the results, you may want to modify the geocoding service’s settings and try to geocode the table again. This process is known as rematching.

Escoger el estilo de direccionamiento Método para encontrar direcciones Define los datos de referencia Asigna campos al estilo de geocodificación Propiedades adicionales Opciones de asignación Creating a geocoding service A geocoding service defines a process for converting address descriptions of locations into geometric shapes. Geocoding services are created and maintained in ArcCatalog and enable you to geocode in either ArcCatalog or ArcMap. The geocoding service defines paths to reference data, algorithms for standardizing address descriptions and matching them to the reference data, and parameters for reading address data, matching the address data to the reference data, and creating output. Geocoding styles With ArcMap and ArcCatalog, you can geocode addresses against geodatabases and file based data sources such as shapefiles and coverages. ESRI provides numerous geocoding styles for you to choose. Each style has different requirements for the information that tables of addresses must contain in order to be geocoded. If your reference data is a geodatabase, select a style name with ‘(GDB)’, otherwise use one named with ‘(File)’. If a style is named with the word ‘AltName’, you can use it to specify an additional table that contains alternate names, for instance the former name of street changed to honor a local dignitary, to the primary street records data. Geocoding reference data In order to find the geographic location of an address, a geocoding service must refer to at least one data source that has both address information and spatial information. A feature class is an example of a data source that includes both types of information. When geocoding an address, a geocoding service searches through the features in the reference data feature class to find the feature that most closely matches the address. The geometry of the matching feature is then used to create geometry for the address. Introduction to ArcGIS for ArcView and ArcInfo (II)

Asignación de campos a estilos de geocodificación
Los estilos categorizan los datos de direcciones 301 Categorias Campos fuente 399 300 398 N New York ST N New York ST Field mapping to geocoding style ArcGIS comes with several predefined geocoding service styles that you can use immediately to create geocoding services. These styles cover some of the most common styles of addresses that you might want to geocode. Each geocoding service style has specific requirements for the reference data that it can use to match data. You can use StreetMap data, feature classes, and tables as reference data for geocoding services. This data may contain some common pieces of information that can be used for geocoding including a prefix direction and type, the street name and type, a suffix direction, and a zone. The above example is using a geocoding style for U.S. Streets. This geocoding style lets you create geocoding services for U.S. addresses. This style can use feature classes with any type of geometry, but typically uses feature classes with line or polyline geometry. Each feature in the reference data represents a street segment with two ranges of addresses that fall along that street segment, one for each side of the street.

These settings control how a geocoding service reads a table of addresses to geocode, how it matches features in the reference data, and what it writes to the geocoded output. Modifying a geocoding service’s settings will impact how well the geocoding service will be able to match addresses to the reference data, as well as what information the geocoding results will contain. Matching options Place Name Alias Table A place name alias table allows you to geocode addresses by their common names, for example ‘City Hall’, instead of by their street addresses. The place name alias table must contain an alias field for storing the common name, in addition to all the required fields for the particular geocoding services style. Spelling sensitivity The Spelling Sensitivity (SS) controls how much variation the geocoding service will allow when it searches for likely matching candidates in the reference data. The spelling sensitivity setting for a geocoding service is a value between 0 and 100. A low value for spelling sensitivity will allow ‘Mane’, ‘Maine’, and ‘Man’ to be treated as match candidates for ‘Main’. A higher value will restrict candidates to exact matches. The spelling sensitivity does not affect the match score of each candidate, only the number of candidates considered to be a potential match. Default SS is 80.

Utilizando el administrador de servicios de geocodificación Existen muchos servicios de geocodificación disponibles Adding a geocoding service in ArcMap Your ArcMap document can contain any number of geocoding services. You can use the Geocoding Services Manager to manage the set of geocoding services contained in an ArcMap document. Introduction to ArcGIS for ArcView and ArcInfo (II)

Tabla de geocodificación
Utilizar los servicios de geocodificación para crear elementos puntuales Los datos de salida son shapefile ó feature class de un geodatabase Geocoding a table When you geocode a table of addresses, you use a geocoding service to create point features that represent the locations of the addresses. You can geocode a table of addresses and save the output as a shapefile or a geodatabase feature class. Introduction to ArcGIS for ArcView and ArcInfo (II)

Registros no asignados
Estadísticas Especifica registros para reasignar Registros no asignados Registros con puntaje bajo Registros empatados Todos los registros Utilizar una consulta Cambiar las opciones de geocodificación Asignación interactiva o automática Unmatched records There are a number of options for specifying which addresses in a geocoded feature class you want to rematch. You can rematch just the addresses that are unmatched, all of the addresses with a match score less than a certain value, all of the addresses with two or more candidates with the best score, or all the addresses. In addition, you can specify a query to use that defines the set of addresses to rematch. You can change some of the geocoding options, perhaps change the spelling sensitivity, when you rematch addresses. When you are geocoding a table of addresses, modifying the geocoding settings does not change the geocoding service that you are using. Only the settings that are used to geocode this table are modified. These settings are stored with the geocoded feature class. The original geocoding service is not modified.

Estado U = Unmatched (No asignado) T = Tied, (Empatado) M = Matched, (Asignado) Score (Puntaje) Side (Lado) ARC_Street (Calle) Attributes in geocoded feature classes When you geocode a table of addresses, a geocoding service creates some special attributes in the output feature class. Status The status field indicated whether or not the address was matched. This attribute has values of ‘M’ for matched addresses, ‘U’ for unmatched addresses, and ‘T’ for addresses where a tie occurred. Score The score field contains the match score of the candidate to which the address was matched. Side The side field contains the side of the street to which an address was matched, if the geocoding service that was used to match the table contains address information for both sides of the street. This attribute has values of ‘L’ for the left side of the street, ‘R’ for the right side, or nothing if the geocoding service could not determine the side of the street. ARC_Street The ARC_Street contains the address information that was geocoded. Introduction to ArcGIS for ArcView and ArcInfo (II)

Añadiendo datos XY en ArcMap
Añadir tablas que contienen campos XY como capa Exportar a shapefile ó a una clase de elemento en un geodatabase Adding x,y data In addition to data sources such as a shapefile, you can also add tabular data that contains geographic locations in the form of x,y coordinates to your map. X- and y-coordinates describe discrete locations on the earth’s surface such as the location of fire hydrants in a city or the points where soil samples were collected. You can easily collect x,y coordinate data using a global positioning system (GPS) device. In order to add a table of x,y coordinates to your map, the table must contain two fields—one for the x-coordinate and one for the y-coordinate. The values in the fields may represent any coordinate system and units such as latitude and longitude or meters. Once you have added the data to your map, the layer behaves just like any other feature layer. For instance, you can decide whether or not you want to display it, symbolize it, set the visible scale, or display a subset of features that meet some criteria.

Determinación de las necesidades del cliente Diseño conceptual y lógico Diseño físico Plan de automatización Proyecto piloto Implementación Metadatos Overview Nothing is more critical to the success of a GIS project than good planning. In this lesson, you will be introduced to the issues and processes involved in designing a GIS database. You will then put some of these concepts into practice in the following lessons as you build a geodatabase and use it to conduct some simple analysis. Introduction to ArcGIS for ArcView and ArcInfo (II)

El procedimiento de diseño de la base de datos
Determinar las necesidades del cliente Diseño conceptual y lógico Prototipo Diseño físico Plan de automatización The database design procedure There is no single correct procedure for database design; the procedure outlined here is a guideline. The database design process is not linear. There are feedback loops, especially between the pilot study, the conceptual and logical designs, and the physical design. Needs assessment Determine the functions that will be supported by the GIS in this time-consuming step. To get the information necessary to complete this task, you could interview potential users, tour operations, conduct inventories of data, hardware, software, and personnel, and conduct educational seminars. Conceptual and logical design Determine database contents and how to logically organize the data in the database. The conceptual and logical design for the project in this course is based on the concept of a shared database using ESRI data models, particularly the geodatabase. Physical design Physically structure the data so that it conforms to the ESRI data structures. A detailed database schema is also implemented in this phase, along with plans for documentation and naming conventions. Automation plan Establish automation procedures. Prepare data for automation and implement the plan. If there are problems during this step, you may need to reevaluate the design of the database. Pilot project Test the functionality, performance, and flexibility of the database design. At least one pilot study should be performed before full implementation of the database. Prototyping Remember to test as you go. Consistent feedback from users can avoid problems later. Proyecto piloto Implementación final Introduction to ArcGIS for ArcView and ArcInfo (II)

Valoración de las necesidades
Defina su objetivo Decida qué es lo que desea obtener Pregunte a la gente correcta lo que se desea obtener Datos GIS database GIS tasks Usuarios Assessing needs Perhaps no step in the database design process is as critical and potentially time-consuming as the needs assessment. There is a good reason for committing the proper attention and resources to this step. The ability of the GIS to operate acceptably is directly related to how well the necessary functions the GIS will perform are understood. To gather the right information, you must ask the right people the right questions. This means conducting detailed interviews with end users, data managers, supervisory personnel, and anyone else who might be impacted by the new system. From these interviews you should try to determine: What tasks are performed using spatial data. What tasks are performed that do not currently use spatial data, but have a spatial component. What tasks are not currently performed, but are desired. Who will be using the system and what their roles will be. What types of products the system will need to produce (maps, reports, etc.). What applications will need to be developed. What data will be needed to fulfill the stated tasks. Will the data be shared among multiple users. What special security measures are necessary.

The conceptual design is a top-level concept of how the database will work. The logical design is a detailed layout that fills in the conceptual design in accordance with a specific data model. This procedure includes determining the database contents (spatial, attribute, and behavior), selecting appropriate geographic datasets, and organizing the content into a series of themes.

Determinando el formato de datos
Escoger un formato que llene sus necesidades Se puede convertir entre formatos, de ser necesario Pensar a largo plazo Shapefiles Archivos CAD Coberturas Determining the data storage format Data storage formats ArcGIS offers you many choices for storing spatial and attribute data. Each format has its strengths and limitations, but if you understand your needs, you should be able to select the ones that will work best for the GIS being developed. Some issues to consider when choosing data formats are: Topology: Coverages store polygon and line topology. The geodatabase has multiple topology options. Shapefiles do not store topology. Vector versus raster data: Raster format is especially suited to data without clear boundaries (continuous data) such as temperature, pollution, and elevation. Vector formats store discrete lines, so they are more suited to discrete data such as streets and parcel boundaries. Consistency: The formats you choose should be standardized within your organization, and easily converted if necessary.

¿Qué es una Geodatabase?
Escalable Validación Personal GDB (.mdb) Espacial: Redes Geometricas, Topología Atributos: Subtipos, Dominios Relación de clases Enterprise GDB (ArcSDE + RDBMS) Why the geodatabase? The geodatabase format offers many unique advantages for geographic data storage. Scalability As user needs for security and data management grow, the geodatabase can meet them. Custom features Because of its COM architecture, custom objects can be programmed that represent real-world features more accurately. Domains and subtypes These properties, easily created and maintained in the geodatabase, make data creation, editing, and maintenance much more efficient and would require special programming to be achieved in other formats. Geometric Networks Using the geodatabase, you can create geometric networks for modeling connectivity and performing trace and path finding analysis. Topology Working with a geodatabase topology is much more flexible than working with coverages because once the topology has been created you can stop at any point in the process. In addition, when you work with the geodatabase you have the choice between assigning or not assigning topology to your data. You can also pick which topology rules you want to use. The coverage model does not offer this flexibility. Personalización Introduction to ArcGIS for ArcView and ArcInfo (II)

Diseño Físico Modelo conceptual detallado y pasos principales
Identificar las fuentes de datos Esquema claro de la base de datos Estructura tabular Relaciones Esquema de codificación Dominios y subtipos Determinar los procedimientos de documentación Convenciones de nombres a utilizar Actualizando los metadatos Physical design There are some physical design issues to take into consideration when designing your database. Data sources Decide which source of data to use for the GIS. This step may involve searching outside the organization. This is an important step because both the cost and quality of the database can be profoundly affected by the choice of data sources. Designing individual datasets Make the final layout of each geographic dataset and independent table. Decide precisely how each data element will be stored and what coding schemes will be used. Determine what relationships will be stored and what the keys will be. Also determine what domains and subtypes will be established. This step is a detailed translation of the conceptual design into a physical layout. Documentation Establish a standardized naming convention for spatial, attribute, and related file data. Determine what information will be stored as the documentation for the database and what the procedures will be to implement it. Introduction to ArcGIS for ArcView and ArcInfo (II)

Esquema de la base de datos
Estructura o diseño de la base de datos Pensar a largo plazo puede economizar esfuerzos posteriormente Nombre de campos Tipo de campos Valores Database schema The schema of a GIS database is its overall structure. This part of the physical design translates the conceptual or logical design into a detailed layout. In addition to the data components, the schema should also take into account the physical storage devices, security issues, and user needs. Once designed, a database schema should be difficult to alter, but possible if truly necessary. The schema is similar to the blueprints for a house. It would be impractical to decide you want a French Tudor style house halfway through the construction of your Victorian cottage, yet you could do it. The key is to know what you want before you start and to plan for it. Relaciones Dominios Introduction to ArcGIS for ArcView and ArcInfo (II)

Escogiendo una proyección para la base de datos
Aspectos a considerar ¿Cuáles propiedades espaciales son las más críticas para sus aplicaciones? ¿Cuál es su área de estudio? ¿Qué tan extensa es su área de estudio? ¿Con quién se compartirán datos y qué tan a menudo? Choosing a database projection Because projecting a three-dimensional surface onto a flat one causes distortion of spatial properties, choosing the appropriate projection can have an important impact on your database. This slide lists some of the issues you need to consider when making this decision. You should also remember that even if you store datasets in different projections, the ArcMap application can still project them on the fly so they all display in the same coordinate space. For this reason, some database designers elect to store their data in decimal degrees of latitude and longitude, then apply a projection when the need arises. Introduction to ArcGIS for ArcView and ArcInfo (II)

Las series de proyección UTM
El globo se divide en 60 zonas de 6 grados cada una Se aplica una proyección Transversal de Mercator a cada zona Redlands se ubica en la Zona 11 Zone 1 Zone 60 11 The UTM projection series The Universal Transverse Mercator (UTM) projection series covers the world between latitudes of 80º south and 84º north. The earth is divided into 60 zones, each spanning 6 degrees of longitude. The zones are numbered 1 through 60, starting at 180º west longitude. The same Transverse Mercator projection is then applied to each zone. The UTM projection is based on a cylinder whose axis is oriented parallel to the plane of the equator, hence the transverse part of its name. Each zone has two lines of secancy. These two lines represent the points of true scale for the projection within the zone. The further a point is from one of these secants, the higher the positional error. The UTM projection is designed for a scale error not to exceed 0.1 percent within each zone. Error and distortion increase for regions that span more than one zone, so UTM may not be the best projection in all cases. The course exercises is built on data using the Universal Transverse Mercator (UTM) projection, Zone 11, Datum: NAD83, Spheroid: GRS_1980. You can learn more about the UTM projection series and other projections in the online documentation. Introduction to ArcGIS for ArcView and ArcInfo (II)

Although there are a myriad of commercial sources and techniques for capturing data, the process usually follows these three steps: 1. Convert the data into the desired format. This could require multiple steps. 2. Correct any spatial errors and add the appropriate attribute data. 3. Aggregate individual pieces of data into the complete representation of your study area. This may also require eliminating some superfluous data. Remember to plan the methods of data automation before beginning this phase of the project and to document each step.

Proyecto piloto Una pequeña prueba focalizada
Determinar la funcionalidad del diseño Muchas veces es mejor retroceder que continuar y luego fracasar Pilot project Conducting at least one pilot study lets you evaluate the design of your database at a relatively low cost prior to full-scale implementation. The design should be tested for functionality, performance, and flexibility. To meet this objective, a pilot study should reflect the types of tasks the GIS will be required to perform. It should also use several different datasets to ensure that the design is working across the board. More than one pilot study may be required.

Contenido Database design Metadatos Overview
When designing and implementing a GIS project, metadata is often overlooked. Keeping good quality and up to date metadata can be very time consuming. However, not keeping metadata for any piece of data can essentially make that piece of data worthless over time. For example, if you generate a feature class and choose not to store the projection information with that feature class, anyone who wants to use your data has to contact you. If you decide to move on to another job and someone else takes over the management of your data, then this data become useless. Creating and updating metadata for every piece of data you generate is crucial. In this lesson, you will explore the different metadata options that are available in ArcGIS. Introduction to ArcGIS for ArcView and ArcInfo (II)

Metadatos: Documentando sus datos

Storing this documentation and keeping it current has long been one of the more frustrating and least-performed tasks in GIS database development, but ArcGIS 8 makes the creation and maintenance of metadata much easier than it has been in the past. The ArcCatalog application contains a special metadata tool that allows you to enter documentation for each component of the database. The information you can store conforms to the requirements of the Federal Geographic Data Committee (FGDC). ArcGIS will automatically capture and store some of the data (the Properties shown on this slide). The user is required to store any other information they believe is relevant. The metadata is stored in Extensible Markup Language (XML), a simple Internet-compliant format. This means that your metadata created in ArcCatalog can be viewed from there or with a Web browser. There are different predefined formats, or stylesheets, for viewing the metadata, but you can also create your own. Introduction to ArcGIS for ArcView and ArcInfo (II)

Estilos que definen como los datos XML se presentan Se escriben utilizando Extended Stylesheet Language (XSL) Estilos ISO FGDC ESRI XML Viewing metadata You can view metadata in ArcCatalog by clicking on an item in the Catalog tree, then clicking the Metadata tab in the display area. There are a number of stylesheets available in ArcCatalog to view metadata, some of these include: FGDC ESRI, FGDC (which is the default), FGDC FAQ, the Geography Network and XML. Stylesheets define how XML data is presented and are written using Extended Stylesheet Language (XSL). XML: The Extensible Markup Language (XML) stylesheet presents the raw XML data and all the tags and values contained in the metadata. FGDC or FGDC FAQ: The Federal Geographic Data Committee (FGDC) stylesheet selects only the information defined by the FGDC standard. The FAQ formats the metadata by frequently asked questions. The Geography Network: Formats metadata as it is seen in the Geography Network. FGDC ESRI: The FGDC ESRI stylesheet selects a subset of the entire body of metadata and presents it as if it was in a tabbed dialog. You can also create your own customized stylesheet for displaying metadata in ArcCatalog. Introduction to ArcGIS for ArcView and ArcInfo (II)

Paper maps If your current data exists in paper map formats, you have two options: either (1) you can digitize the features off the map using a digitizing tablet, which can result either in a shapefile or a coverage, or (2) you can scan the entire map creating a raster image, which you can later use the ArcGIS ArcScan extension to clean it from unwanted cells ( e.g., dimensions, labels, dust, etc.) and vectorize the raster into either a shapefile, a coverage, or a geodatabase feature class. Import or export or load digital data There are several tools in both ArcToolbox, ArcCatalog, or ArcMap that can be used either to import or export or load different types of data (such as shapefiles, coverages, raster, images, CAD files, geodatabase feature classes) to or from the geodatabase. Each of the ArcGIS three applications have different types of tools.

Scanning Scanning requires special hardware that creates a raster image of a hardcopy map. The resulting product may be converted directly to a grid or vectorized—converted to a vector coverage. ArcInfo provides special vectorization software for converting grids and images to coverages. An automatic vectorization tool is provided with the core ArcInfo package; more specialized tools are supplied with the GRID™ and ArcScan™ software extensions. Georeferencing of the image, grid, or resulting vector dataset must be done before geographic analysis can be performed. Table digitizing Often, data is captured with special digital tracing hardware. Table digitizing produces a vector coverage, shapefile, or geodatabase feature class, which may or may not be georeferenced while tracing. Tics can be used to reference locations with known, real-world coordinates to locations on the digitizing tablet, allowing coordinates to be georeferenced during automation. Alternatively, features can be moved in coordinate space after tracing. Both methods will produce the same result. Heads-up digitizing Heads-up digitizing is a combination of scanning and manual digitizing. With heads-up digitizing, a map is scanned and the resulting image is traced on-screen with a mouse. The image may be georeferenced, producing a georeferenced dataset when traced, or the resulting dataset may be moved to real-world coordinate space after tracing.

The spatial reference for a feature class includes its coordinate system (for example, geographic, or a projected coordinate system such as UTM or State Plane) and its spatial or coordinate domain. The coordinate system is composed of a projection, a datum, an ellipsoid, and units. Other elements such as the prime meridian, a coordinate shift, and a zone may also be defined. The spatial reference also includes the coordinate extent or spatial domain of the feature class or the feature dataset. Extents can be set for the x- and y-coordinates as well as z, usually an elevation value, and m, a measurement along a linear feature. The same spatial reference is shared by all the feature classes in a feature dataset. Any standalone feature class can have its own spatial reference associated with it. When importing spatial data (e.g., shapefile or coverage) to a feature dataset that has a different coordinate system, that data will automatically be projected to match the spatial reference of the feature dataset.

The precision describes the number of system units per one unit of measure. A spatial reference with a precision of 1 will store integer values, while a precision of 1,000 will store three decimal places. Once the spatial reference for a feature dataset or standalone feature class has been set, only the coordinate system can be modified—the spatial domain is fixed. The spatial domain for a feature class or feature dataset cannot be changed. If the required x-, y-, m-, or z-value ranges for your database change, the data has to be reloaded into feature classes with a spatial reference that accommodates the new value range. When you load data into the geodatabase, you must store your coordinates at a specific precision. For best results, ensure that the chosen precision will support the accuracy of your data. The ArcCatalog loading wizard will look at your data and determine defaults for your precision and database growth. Naturally, it is impossible for ArcCatalog to understand your intentions for the data you are loading, so the default settings may not always be the best choice for your application. It is important that you understand what the default spatial domain settings mean and how to change them if necessary. The geodatabase stores coordinates as a 4-byte integer that has a maximum value of 2,147,483,648. You decide what the units represent. For instance, if you need to store meter accuracy, then you have 2.1 billion meters to work with. If you could decide to store centimeters, you would have 2.1 billion centimeters to work with. These units are called storage units. Because you should set your storage units based on your accuracy, you may decide to make your storage units an order of magnitude greater than your current needs to anticipate more accurate data in the future. Map units are the measurement units of your data, and have nothing to do with accuracy. They are the units that represent measurements. For example, the meter is the standard unit for UTM data, while the foot is the standard unit for a state plane coordinate system. 2.14 billones de unidades de almacenaje Introduction to ArcGIS for ArcView and ArcInfo (II)

You have options to select a coordinate system from the many standard coordinate systems stored by ArcGIS, to import the spatial reference information from an existing source (perhaps another feature class), or to create a new coordinate system. Setting the spatial reference includes setting the coordinate system information and the domains for the x,y,z, and m coordinates. Z values usually store elevation values, while the m coordinate can be used to store a measure along a feature. Z domain and M domain tabs These tabs will only appear in the Spatial Reference Properties dialog (like the example above) if the ‘Contains Z values’ and ‘Contains M values’ field properties were turned to ‘yes’.

On the Feature Dataset dialog, fill in the name for the new feature dataset, and click the Edit button to set the spatial reference for the new feature dataset. A feature dataset is a container for spatially or topologically related feature classes. The feature classes that will combine to form a geometric network or feature classes that share exact boundaries belong in a feature dataset. To maintain these topological relationships, all feature classes in a feature dataset must share the same spatial reference. The spatial reference can be set as a property of the feature dataset, guaranteeing that all feature classes you add to this feature dataset will automatically be projected to match the spatial reference. 2 Select New > Feature Dataset 4 Ajustar la referencia espacial Introduction to ArcGIS for ArcView and ArcInfo (II)

If existing data meet your needs, it is often quicker and less expensive to convert it to an ESRI format than to create a new database from scratch. Both ArcView and ArcInfo have tools to convert existing data in a number of formats into coverages, shapefiles, or geodatabases.

Importando datos desde Internet
Añadiendo datos desde un Feature Service a ArcMap Exportar a un shapefile ó a un GDB feature class Importing data from Internet sources The Internet is a vast resource for geographic data. Now you can use this data directly on your maps through Geography Network and other Internet servers. Geography Network is a global community of data providers committed to making geographic content available to the public. Published from sites around the world, Geography Network gives you immediate access to the latest maps, data, and related services over the Internet. Use Geography Network to search for and explore maps and other geographic content. When you find what you want, add it directly to your maps in ArcMap. Types of Internet services ArcIMS provides two types of map services: an image map service and a feature map service. An image map service works by taking a snapshot of a map on a server and delivering it to you as an image. A feature map service streams the actual map features to you, providing more sophisticated functionality because the geographic features are directly accessible by ArcMap. When you add a feature map service to ArcMap, you will see a new layer corresponding to each of the layers in the feature map service. You work with these layers in the same way you work with layers based on other data sources. Introduction to ArcGIS for ArcView and ArcInfo (II)

Defining a projection for your data does not alter the data in any way—it only tags on the projection information to the spatial data. Changing the projection will alter your data as it moves into a new projection. Defining a projection ArcMap expects coordinate system information to be stored with the data source. For a layer in a geodatabase, this information is part of the layer’s metadata. For coverages and shapefiles, it is stored on disk in a separate file named after the data source but with a .prj file extension (for example, streets.prj). These files are optional files; thus, you may still need to define the coordinate system for one of these data sources. You can create a .prj file using the Define Projection Wizard in ArcToolBox. Changing the projection ArcGIS supports many different projections and is able to project your data from one projected coordinate system to another. This requires that the coordinate information is known for your data. Solamente ArcInfo Introduction to ArcGIS for ArcView and ArcInfo (II)

Domains and subtypes offer a way to organize your data so that certain operations, such as editing, become more efficient while the integrity of the attributes is maintained. Subtypes are a way to group features of one feature class into subsets based on an attribute value. In the example above, the Streets feature class is divided into two subtypes which are based on the value of the CLASS attribute field on the feature class table. A domain is just a declaration of acceptable attribute values. Whenever a domain is associated with an attribute field, only the values within that domain are valid for the field. In other words, the field will not accept a value that is not in the domain. Introduction to ArcGIS for ArcView and ArcInfo (II)

Se puede escoger un subtipo por omisión Requiere valores enteros, el usuario añade las descripciones Carreteras sin subtipos Organiza la CLASE en grupos Valor CLASE Descripción de subtipo Carreteras locales Autopistas Using subtypes Subtypes give you a method to divide your features into logical groupings based on an attribute value. In the example above, new subtypes, Local Streets and Major Highways, were created based on values from the CLASS field in the Street feature class. Any feature with a CLASS value of 1 will belong to the Local Streets subtype, and those features having a CLASS value of 2 will belong to the Major Highways subtype. Creating subtypes requires the functionality of ArcEditor or ArcInfo. Once created, subtypes can be used at the ArcView level to symbolize and edit features according to their subtype. You can also enforce data integrity for the entire subtype by associating a domain. In the above example, the selected street is part of the Major Highways subtype, and therefore can only accept values from the associated Highway Types domain.

Only integer fields may contain subtypes; therefore, only integer types, short or long, will appear as possible subtype field choices. Choose the subtype field, then enter the appropriate code and description. Optionally, set the default value. Default field values Setting a default subtype value is useful for editing. For instance, a new feature will inherit this subtype and any associated defaults for other fields. Set the defaults for any other field or fields based on your subtype value. For instance, the Local subtype of the Streets feature class may have a Type default of ST (Street) and a Road Condition default of Good. You can apply subtypes to any geodatabase table, whether or not it has records. You can apply the subtype and validate the attribute values after records have been added to the table. The Use Defaults button You may want to copy default values from one subtype code to another subtype code. The Use Defaults button lets you copy the default values and domains from the default subtype to any other subtype code. To use this option, first enter appropriate default values and domains for your default subtype. Next, click on any subtype code other than the default code. Finally, click the Use Defaults button to copy all your default subtype’s default values and domains to the other subtype code. Introduction to ArcGIS for ArcView and ArcInfo (II)

Editando con subtipos Añadir características por subtipo
Los nuevos elementos heredan automáticamente los valores por omisión de los subtipos Subtipos Editing with subtypes Subtypes can make editing more efficient by automatically attributing new and updated features. For example, if you add a new feature that belongs to the Local subtype, it will automatically have the default values of Local Streets. This is insurance against data entry error. Defining subtypes simplifies the attributing process because your choices are listed by description and you do not have to remember all the codes. When adding new features, first choose the appropriate subtype from the Editor’s Target list. As you add features, they automatically inherit the subtype code and the defaults you created for any other fields in the table. Editing existing records You can also apply subtypes to existing records. Select records through a spatial or attribute query, then edit the subtype by choosing from a pulldown menu that lists all your available codes. This can be done directly in the table or in the Attribute Editor. The chosen subtype will set or update the default values for other attributes. If you are creating data, this will not cause problems because your defaults are usually set appropriately for your table. Realize, however, that choosing a subtype for a preexisting record may complicate your situation because the default values will overwrite your previous values.

Domains are user-defined lists of valid attribute values for a column in the entire table or just the features grouped into a subtype. You can apply domains to your columns to prevent attribute errors and provide a way for you to validate records that were added before the domain was applied. There are two types of domains: Range and Coded Value. Range domains specify acceptable starting and ending numeric values. These can either be integers (9 to 66) or numbers with decimal places (9.15 to 19.66). Coded value domains are explicit listings of acceptable codes. These domains can be any value compatible with the field type. For instance, a coded value domain may be specified as a short integer field type. A domain named SEVERITY may include 1 (moderate), 2 (medium), and 3 (severe). A property of the geodatabase Because a domain is a geodatabase property, it is available to any table in the geodatabase. The only caveat is that the field or subtype to which you apply the domain must share its field type. For instance, text type domains can only be applied to text type fields.

Using domains helps to ensure data integrity by limiting the choice of values for a particular field to only those within the domain. Validation for coded value domains is accomplished by forcing the user to choose field values from a dropdown list. Range domains are automatically validated during editing.

Then, under Domain Properties, you can set the field type to which this domain will be applied and an acceptable range of values for this domain. Creating coded value domains in ArcCatalog To create coded value domains, you use the same process used to set up a range domain, except that you have to specify the acceptable codes.

Incorporating topology into your datasets allows you to better model the real world. The primary spatial relationships you want to model are adjacency, coincidence, and connectivity. Adjacency Adjacency allows you to identify which land owners or soil types share a common boundary with each other. Coincidence Coincidence lets you identify the bus routes on top of roads. Connectivity Connectivity allows you to identify a route to the airport, or connect streams to rivers, or follow a path from the water treatment plant to a house.

The coincidence of features is determined on-the-fly within the edit session, as opposed to being stored as a series of tables in the database. Multiple feature classes can be edited simultaneously if they contain coincident geometry. For example, it is possible that a parcel can share a common boundary with polygons from the zoning, land use, and subdivision layers. Using the topology editing tools, moving a shared boundary can automatically update all your feature classes at once or you can select which individual shared features will be updated. The spatial integrity is managed by a set of rules defined by you, which will help you find and fix topologic errors. With streets, you may decide to implement a rule that the streets must not intersect each other. Mover una tubería y sus válvulas Introduction to ArcGIS for ArcView and ArcInfo (II)

New features can be added which may create errors in your topology. These errors can exist in the topology and the data is still fully available for view, query, or analysis operations. Dirty Areas Following the initial creation of a topology, the extent of all features is considered a dirty area until the topology is validated. A dirty area is created any time: A feature’s geometry is changed: a feature is modified, a new feature is created A feature’s subtype is changed Versions reconciled Topology properties are modified Dirty areas are generated because they may contain existing or undiscovered topology errors. Dirty areas allow the topology to optimize the validation process by limiting the extent of data whose spatial relationships need to be evaluated. This allows selected parts, rather than the whole extent of the topology to be validated after editing. Rangos Arreglar errores Excepciones Introduction to ArcGIS for ArcView and ArcInfo (II)

Right-click on the feature dataset, and click New > Topology. Requirements for creating a Topology In order to create a topology, the following rules apply: Feature dataset Topologies can only be created inside a feature dataset because all feature classes must have the same spatial reference. A single feature dataset, however, may have multiple topologies. Simple feature classes Only simple feature classes can participate in a topology. A feature class can only participate in one topology at a time. The following feature classes can not participate in a topology: Annotation (neither static nor feature-linked) Dimension Geometric network feature classes Geodatabase topology When you create a topology it stores groups of properties and topology features in the geodatabase. The groups of properties include cluster tolerance, ranks, and rules. The topology features are errors, exceptions, and dirty areas. Tolerancia Rangos Reglas Errores Excepciones Areas sucias Introduction to ArcGIS for ArcView and ArcInfo (II)

(1 cm / 100 cm en un metro) / 10 (orden de magnitud) = 0.001
Tolerancia Cluster Es una distancia en la cual toda la geometría es considerada idéntica ó coincidente Hacer su tolerancia 10 veces más pequeña que la exactitud más elevada de sus datos Tolerancia Cluster Después de validar la topología El validar la topología se realiza luego de su creación Cluster tolerance A distance range in which all vertices and boundaries are considered identical, or coincident. The default is the inverse of the precision of the feature dataset. Determining Cluster Tolerance The basic rule of thumb is to set the cluster tolerance to a value that is an order of magnitude less than the accuracy of your data. Units are Feet If the map units of your data are measured in feet, and the highest accuracy of your data is one inch, then your precision is 12. To make the cluster tolerance an order of magnitude less than that, use the formula: The inverse of the precision / 10 (order of magnitude) = (1 / 12) / 10 = ft. You are thus minimizing the amount of movement in your data that is induced by the cluster tolerance. Units are Decimal Degrees If the map units of your data are measured in angular units like Decimal Degrees, you would divide your highest accuracy data in meters by the number of meters in one angular unit at the equator. To make the cluster tolerance an order of magnitude less than that, use the formula: (Highest accuracy in meters / (SpheroidsSemiMajorAxis in meters * RadiansPerAngularUnit)) / 10). For example, if you wanted to preserve 1 centimeter accuracy using the WGS_1984 spheroid using decimal degrees the cluster tolerance would be: (0.01 / ( * )) / 10, which equals: e-9 Note: In the example above, 1 cm is the accuracy value, and 1 meter is the map unit, which is where the 100 cm value came from. (1 cm / 100 cm en un metro) / 10 (orden de magnitud) = 0.001 Introduction to ArcGIS for ArcView and ArcInfo (II)

You determine the number of ranks (up to 50; 1 is the highest, and 50 is the lowest) based on your data, and the priority of the rank of each feature classes in the topology. This allows you to integrate less-accurate data to match data of higher accuracy. Crack Points Crack points are created as part of the topology validation process where vertices are created at the intersection of feature edges. When feature classes have EQUAL ranks: Crack points move to end points. Multiple endpoints are moved to an average location. When feature classes have UNEQUAL ranks: Endpoints, crack points, or both of lower ranked (higher numbers) features move to match endpoints/crack points of higher ranked (lower numbers) features. Snap low quality feature classes to high quality feature classes. For example, if you had parcel lines and zoning feature classes, and the parcel lines were entered using COGO measurements from a plat, you would want to set this feature class with a rank of 1. If the zoning data was digitized with a tablet, you would want to set its rank lower (e.g., to 2), so the zoning boundaries would snap during the validate to match the parcel lines.

Topology rules are used to specify and constrain the topological relationships that must exist within the topology. Topology rules can be defined for all feature geometry types. Rule files can be edited in ArcCatalog but not with a text editor. ArcGIS Version 8.3 currently supports 26 different topology rules: 9 polygon rules, 12 line rules, 4 point rules, 1 default rule related to cluster tolerance. Future releases of ArcGIS will continue to add new rules to this list. Saving Rules Topology rules can be saved to a binary file with a (*.rul) extension. A Rule Set file can be saved in order to preserve the rules that have been set up so they can be applied to another topology or shared with other users. NOTE: Topology rules cannot be created in a UML database design created with Visio. However, a Rule Set file can be created and distributed for databases whose schema has been generated from UML inside ArcCatalog. Differences in feature class names can be remapped when the rules are loaded. Topology Rules poster You can view or print a copy of the Topology Rules poster by going to the ArcGIS Desktop Help.

Validated – Errors exist Data has been validated after initial topology creation or edits were made and errors are existing in the topology. Validated – No Errors Topology has been validated and the topology is error free. Introduction to ArcGIS for ArcView and ArcInfo (II)

Validando la topología
Validando la geometría del snap basado en la tolerancia del cluster Identificando errores ¿Cuando validar la topología? Después de la creación inicial Después de cada operación de edición Antes de salvar Una vez a la semana Validating a topology Validating a topology evaluates the topology rules, and will create errors if it finds features which violate the rules. When you validate a topology, the geometries of features are integrated based upon the cluster tolerance, and vertices may be added to features within the cluster tolerance so that they can become coincident with other features in the same layer or in another layer. This does not split lines to create new features. It simply inserts vertices. During the validation, vertices that are within the cluster tolerance may be snapped together. A large cluster tolerance may cause undesirable results, because all vertices within the cluster tolerance will be modified to be coincident. On the other hand, a small cluster tolerance may not integrate vertices, and therefore could cause errors. Deciding when to validate a topology is left to the discretion of the user or database administrator. Validation can be done as often as after every edit operation or as infrequent as once a week. There are three different ways to validate a topology, but validating prior to saving edits is not required. ArcMap Validate based upon a user specified area. Validate the visible extent. Validate entire topology. ArcCatalog Validate the entire topology. Áreas específicas Toda la topología Área de trabajo actual Introduction to ArcGIS for ArcView and ArcInfo (II)

A violated rule determines error geometry and contains information on what rule was violated, and which features created the error (parentage). If an error in the topology is detected, an error feature is created. Error Features The rule which is violated determines the geometry of the error feature. Error features contain the rule that was violated and which features created the error (parentage). Below are some examples of errors and the error geometry that is created: Error Shape Rule Point Dangle (Parcel lines do not snap at end points) Line Intersection (Street segments have overlaps) Area Overlap (Parcel polygons that overlap) Introduction to ArcGIS for ArcView and ArcInfo (II)

The Error Inspector and the Fix Topology Error Tool. The Error Inspector allows you to search for errors and exceptions by category and extent. You can limit your search to just a certain type of error. You can do so by clicking the down arrow for the Show input field and select a certain rule. The listing in the Error Inspector will show the details of only those errors that pertain to the selected rule. You can right-click on any error (row) to access a context menu with added functionalities. You can pan/zoom to that error, select the feature which is in error, fix it with any of the commands available for fixing that error, or you may chose to mark it as an exception.

With ArcMap, you can edit all of your feature classes with one common user interface. ArcMap contains sophisticated CAD-based editing tools that help you construct features quickly and easily while maintaining the spatial integrity of your GIS database.

Seguridad de edición Seguridad de edición para prevenir la corrupción de datos Otras personas no podrán editar los elementos con las que usted está trabajando Personal geodatabase Un editor—Lectores múltiples El primer editor bloquea la base de datos completa Enterprise RDBMS formato geodatabase Multiples editores—Multiples lectores El versionamiento permite múltiples editores GIS Database Editing security Editing security measures are necessary to ensure that multiple editors do not attempt to edit the same feature at the same time causing database inconsistency. The two formats of the geodatabase have different available security measures. The personal geodatabase performs an entire database lock when an editing session is started. This prohibits anyone from editing any of the feature classes in the geodatabase except the user who started the editing session. This type of security works well when there is no need for multiple users to edit the database simultaneously, but it can be inflexible in other circumstances. With an ArcSDE geodatabase, in an enterprise RDBMS format, multiple editors are allowed through a process called versioning. The versioning process is covered in detail in the Introduction to ArcSDE class. See the ESRI training Web site ( for more details on this course. Introduction to ArcGIS for ArcView and ArcInfo (II)

Herramienta de creación de elementos
Crear elementos en la capa activa Dividir Buffer Copiar paralelos Union Intersección Clip Crear elementos en la misma capa Split Merge Feature creation tools From the Editor menu, there are a variety of tools for creating new features. Tools that create features in the target layer may use features selected in other layers to create new features. For example, create a new water main parallel to a road feature. Tools such as Split and Merge will create new features from features in the same layer. Introduction to ArcGIS for ArcView and ArcInfo (II)

You can also use this command when you want to split a line at a certain percentage of the original length. For example, you can use the Split command to split a power line at a known distance along the line when you want to add an electrical pole that requires its own service. The Split dialog box displays the length of the original feature in current map units to help you split it accurately. When you split the line using the Split command, the attributes of the original line are copied to each of the new lines. Divide The Divide command creates points at a given interval along a line. For instance, you could use Divide to place utility poles along a primary. You can create a specific number of points that are evenly spaced, or you can create points at a distance interval you choose. Introduction to ArcGIS for ArcView and ArcInfo (II)

Dos polígonos discretos en una capa activa
Buffer El buffer selecciona elementos a una distancia específica Dos polígonos discretos en una capa activa Buffer You can create a buffer around a feature by using the Buffer command. For instance, you might use Buffer to show the area around a well that is contaminated or to represent a floodplain around a river. You can buffer more than one feature at once, but a separate buffer will be created around each feature. Introduction to ArcGIS for ArcView and ArcInfo (II)

Copiar paralelo Copia una línea paralela a la original
Se coloca al lado derecho del elemento Crea elementos en una capa activa 20 Copy Parallel The Copy Parallel tool allows you to create a new feature parallel, on either side, to an existing one. You will be able to specify the distance between the original line and the new parallel line. A positive distance between the parallel lines will create the new parallel line to the right side of the feature; negative values will create the new parallel line to the left. It would help to change the symbol from a simple line to one with an arrow in order to see this relative location (i.e., to see the ‘right side’ of the feature). The new parallel line is created as a new feature in the target layer. You can use the Copy Parallel command, for example, to create a street centerline or a gas line that runs parallel to a road.

Unión e Intersección Crea elementos en la capa activa No elimina los elementos originales Unión Intersección Creando un tema de ventas Union and Intersect The Union command combines features from different layers into one feature while maintaining the original features and attributes (table fields). For example, you can create a sales territory from several ZIP codes. You can also create a multipart feature using the Union command by combining nonadjacent features from different layers. For example, to create a sedimentary rock polygon in a new rock classification layer given selected clay and quartz polygons in an existing rock composite layer, you would use the Union command to combine the clay and quartz features to create a new multipart sedimentary rock feature in the rock classification layer. Although the features may be from different layers, the layers must be of the same type—either line or polygon. The new feature is created in the current layer without attribute values. The Intersect command creates a new feature from the area where features overlap. For instance, you can create a new sales territory out of overlapping trade areas. You can find the intersection between features of different layers, but the layers must be of the same type (either line or polygon). The original features are maintained and the new feature is created without attribute values in the current layer. You must manually enter attribute values for the new feature.

Merge Reemplaza el elemento existente con uno nuevo En la misma capa Elimina los elementos originales Líneas ó polígonos Combinando dos parcelas Merge The Merge command combines features of the same layer into one feature. The features must be from either a line or a polygon layer. You can also merge nonadjacent features to create a multipart feature. For example, you could merge the individual islands that make up Hawaii to create a multipart polygon feature. When you merge features a dialog appears asking the user to choose which feature the other features will be merged with. The new feature’s attribute values are copied from the feature that the user selects. Introduction to ArcGIS for ArcView and ArcInfo (II)

Editando topologías en ArcMap

You selected which feature classes participated in the topology, defined rules for the topology and validated to identify potential errors in the data. ArcGIS provides topology tools to analyze, visualize, report and if necessary, repair the spatial integrity of the data after it is initially created as well as after editing. As the geodatabase is used and maintained, new features are added and existing features are modified. Data editors update features in the geodatabase and use the editing and topology tools to construct and maintain relationships between features. Depending on the work flow of your organization, the topology may be validated after each edit session or on a schedule. The Topology toolbar provides a series of tools for editing and managing coincident geometry in ArcMap. In this lesson, you will see there are two different types of topologies that can be edited with ArcMap: Geodatabase Topology and Map Topology. Geodatabase topology Regardless of whether a topology is based upon a feature class in a personal geodatabase or an ArcSDE geodatabase, an ArcEditor license is required to create the topology and edit the topology, layers, or both that participate in a topology. You’ll remember that a geodatabase topology consists of a persisted set of user-defined rules and properties that are applied to your data. Introduction to ArcGIS for ArcView and ArcInfo (II)

The spatial relationships between features participating in a geodatabase topology or map topology are not persistently stored in the database, but discovered on-the-fly while editing. Using the Topology Edit Tool in ArcMap, coincident geometries can be determined with shapefiles and geodatabase feature classes. This tool also permits multiple feature classes to be edited with a single edit operation. When features in the topology have parts that intersect or overlap, the lines (edges) and points (nodes) that define these parts are shared. For example, a stream may have a coincident line (edge) that is shared between a state, county, city, parcel, zoning, and land use polygon. Selecting this coincident line with the Topology Edit Tool and then using the Sketch Tool with the edit task set to Reshape Edge, will allow you to simultaneously edit many layers. Shared lines (edges) are determined for all the layers that participate in a geodatabase topology whether they are in the map or not. Conversely, if a map topology is being used, shared lines (edges) are only determined for the layers that have been selected to participate in a map topology.

These tasks allow you to work with shared edges. The Reshape Edge task is similar to Reshape Feature, but applies only to shared edges. Using this edit task lets you reshape a shared edge with a sketch. The Modify edge task allows you to edit the vertices of an edge in the edit sketch.

Crear polígonos de líneas
La herramienta de construcción de elementos utiliza las líneas seleccionadas Crear un nuevo elemento en la capa destino Se pueden considerar elementos existentes La herramienta ArcCatalog procesa los datasets completos Create polygon from lines The Construct Features command on the Topology toolbar, provides a way to generate new polygon features from a selection containing lines, polygons, or both. When the option to consider existing features is chosen, selected line features can be used to split or append polygon features in the target layer. This can be extremely beneficial for parcel maintenance applications where it is necessary to maintain coincident parcel lines and parcel polygons. Digitize, Trace (ArcScan), or Traverse the parcel lines and use them to construct (split or append) parcel polygon features. You can also create polygons from lines within ArcCatalog. The Polygon Feature Class from Lines tool takes one or more existing line or polygon feature classes in a feature dataset and creates new polygon features from the closed shapes that are defined by the intersection of all the lines or polygon edges. A polygon feature class can be created using a line feature class to supply the boundary lines and an optional point feature class to supply the attributes. The input and output layers are required to be from within the same Geodatabase. Partir poligonos Anexar poligonos Introduction to ArcGIS for ArcView and ArcInfo (II)

Topología de mapa Edición de geometría coincidente sin una topología persistente Feature classes o shapefiles Deben de estar en la misma geodatabase o carpeta Feature classes pueden estar en distintos feature datasets Se permite para topología con ArcView A map topology can be applied to simple features in a shapefile or to simple feature classes in a geodatabase. The feature classes that participate in the map topology must be in the same folder or geodatabase. A map topology cannot be applied to feature classes that participate in a geometric network. A map topology creates topological relationships between the parts of features that are coincident. You can choose the distance, or cluster tolerance, that defines how close together edges and vertices must be in order to be considered coincident. The cluster tolerance is typically a very small actual ground distance. Setting large cluster tolerances can result in features being collapsed or distorted when vertices with a given feature snap together. You can also specify the feature classes that you want to participate in the map topology. You do not specify any topology rules for a map topology. All edges or vertices of features in the map topology that fall within the cluster tolerance are considered to be topologically shared. You edit shared edges and vertices in a map topology in the same way, and with the same tools, as you would edit a geodatabase topology. Because there are no topology rules, there is no need to validate a map topology, and there is no creation of error features. Introduction to ArcGIS for ArcView and ArcInfo (II)

Comparación funcional de la topología
Topología de Geodatabase Topología de mapa ArcEditor Topología de mapa ArcView Herramienta de edición de topología Mostrar elementos compartidos Planarize Líneas Construir elementos You can build topological relationships between features with a geodatabase topology or a map topology. With a map topology, you have access to different editing tools depending on what license of ArcGIS you have. Geodatabase topology The geodatabase topology is actually stored in the geodatabase. You must have an ArcEditor or ArcInfo license to create or edit a geodatabase topology. Because the topology is stored in the geodatabase you can store rules, errors, and exceptions with the topology. The geodatabase topology allows you to use all the validation and editing tools available on the topology toolbar. Map Topology using an ArcEditor or ArcInfo license The Map Topology allows you to perform topological edits on shapefiles or feature classes without creating a topology in the geodatabase. When you are have an ArcEditor license you can use the Topology Edit, Show Shared Features, Planarize Lines and the Construct Features tools to edit the map topology. Map Topology using an ArcView license Creating a map topology works exactly the same as it does with an ArcEditor license. The main difference between the two licenses is the ArcView license only allows you to edit with the Topology Edit and Show Shared Features tools.

Edición simultanea de límites coincidentes 1 Topología de mapas Mostrar elementos compartidos 5 3 Herramienta de edición de topología 2 Map Topology Tools To create a map topology, you need to start an editing session; this will enable the Map Topology command. Once you click on this command, the Map Topology dialog will appear. From here you can choose which layers you want to participate in the topology. You will also choose a cluster tolerance. The cluster tolerance represents the precision of your data. It is a tolerance value in map units where all vertices within that tolerance will be snapped together to create shared geometry. As soon as you generate the map topology, you can use the Topology Edit Tool and the Topology Modify Edge and Reshape Edge edit tasks (Note: do not get these confused with the Modify Feature and Reshape Feature tasks) to modify coincident features. You can also use the Show Shared Features command to display all shared features for any given edge or node.

¿Porque utilizar un ajuste espacial?
Alinear los datos vectoriales para una mayor exactitud Datos digitalizados en unidades de mesa digitalizadora o scanner Menos exactitud de los datos Usualmente se agregan datos posteriormente Spatially adjusting data Spatial adjustment allows you to adjust the location of features to match more accurate data in your database through the processes of transform, rubbersheet and edge match. You will need to spatially adjust data that has been digitized or scanned to move it from the units of the digitizer or scanner—for example inches—to match the rest of your data in real world units. You can also use it to adjust lower accuracy data to higher accuracy data. Examples would include: Rubbersheeting the edge of a lakeshore to match the lake outline on a new orthophoto. Edgematching streets or streams along the borders of two municipalities. Once data has been adjusted to match the higher accuracy data, the next step is often to aggregate this data into the more accurate data. In this lesson, you will review the different spatial adjustment tools and the different options in ArcGIS for aggregating data.

Often, you need to make adjustments to integrate new data to existing data or match less accurate data to more precise data. The Spatial Adjustment tools allow you to edge snap, rubbersheet, and transform spatial features, and also transfer attributes from one feature to another. This new toolbar works in conjunction with the ArcMap Editor Toolbar within an ArcMap Edit session. Spatial adjustments are performed interactively in ArcMap and may affect a selected set or all features in a layer. While the spatial adjustment methods differ, all are accomplished by using displacement links to define the source points in the data being edited and the destination points in the control data. Displacement links may be added interactively or in a batch process. The types of adjustment supported are: Transformation (Affine, Projective, Similarity) - The adjustment affects all of the features in the input layer equally. Root Mean Square errors are calculated to indicate the accuracy of the derived transformation. Rubbersheeting (Linear, Natural Neighbor) - The adjustment is applied piecewise throughout the layer or throughout the selected features of the layer. No errors are calculated. Edgematching (Smooth, Linear) Uses rubbersheeting to match features at the edge of layers. The adjustment only affects selected features. No errors are calculated. Through the spatial adjustment toolbar you are also able to transfer the attributes of features to other features. Introduction to ArcGIS for ArcView and ArcInfo (II)

Transformación Cambiar de localización de elementos en coordenadas espaciales en 2 dimensiones Convierte los datos de unidades de digitalización o de scanner a unidades del mundo real Se puede variar la información dentro del sistema de coordenadas, por ejemplo de pies a metros Transforming features Transformation from one coordinate system to another is used frequently in GIS. The effect of a transformation varies from simple changes of position and direction, without changing shape or size, to a uniform change in scale (with no change in shape), to changes in shape and size of varying degrees. Transform can be used to move features that were digitized in inches or centimeters to the correct real world coordinates. It could also be used to move features within the same coordinate system; for example, you could transform features from UTM kilometers to UTM meters. Transformation (Affine, Projective, Similarity) - The adjustment affects all of the features in the input layer equally. Root Mean Square errors are calculated to indicate the accuracy of the derived transformation.

Métodos de transformación
La transformación trasladará, rotará, y escalará los datos Utilice los métodos de Afinidad (Affine), Similaridad (Similarity), o de proyección (Projective) El método de afinidad puede Rotar Trasladar Transformation methods Depending on the method used to transform your data from one coordinate system to another, the transformation may translate or shift features in coordinate space, scale features in size, rotate, or skew them. ArcGIS supports the three transformation methods summarized below. The ArcGIS Help provide more information on the mathematical functions used for the transformations. Similarity This method is also sometimes referred to as an orthogonal or two-dimensional linear conformal transformation. It is commonly used to adjust data between two similar coordinate systems; for example, to change the map units of data from one linear unit to another. This method will translate, rotate, and scale features. A minimum of two displacement links are required for this four parameter transformation. Affine This method expands on the similarity transformation by allowing two scale factors instead of one, and will allow features to be skewed while being rotated. There is a minimum of three links required to perform this six parameter transformation. Transforming digitized data to real world coordinates is a good example where this transformation is applicable, as it allows for the small distortions such as stretch, shrink, and skew that occur to paper and other media that is digitized. Projective This is a specialized transformation used to transform coordinates digitized directly off high altitude aerial photography or aerial photographs of relatively flat terrain. It is an eight parameter transformation and requires a minimum of four links to perform. Sesgar Escalar Introduction to ArcGIS for ArcView and ArcInfo (II)

Creando asociaciones de desplazamiento
Elementos gráficos definen la fuente y el destino Crear manualmente o cargar de asociaciones “links” o un archivo de puntos de control Crear archivos de asociación “links” desde los “links” existentes Creating displacement links Links are used to define how an adjustment affects a dataset. A link is a displacement vector that represents a source location to a destination location. Links are graphic elements in a map and are always displayed as arrows with the arrowhead pointing towards the destination. You can change the symbol, size, and color of displacement links from the Adjustment Properties dialog from the Options command on the Spatial Adjustment menu. The Spatial Adjustment toolbar has tools to manually add a displacement link, to modify an existing link, and a tool to automatically add multiple links between two selected features. The current snap environment is honored when manually adding displacement links. Create links from text files You can also create links from coordinates saved in a link file. A link file is a text file that contains a list of X, Y source and X, Y destination coordinates. A link file can be comma, space, or tab delimited and may contain ID values that precede each record. When you open a links file from the Links submenu, the source and destination displacement links will be automatically created based on the coordinate locations in the link file. You can also create links based on a control points file. A control points file contains the X and Y destination coordinates and may contain ID values for each record. When a control points file is opened, the Control Points Window dialog will open and display the coordinate locations. These locations will become destination points for new displacement links. Double-clicking or right-clicking and choosing Add link will create a link starting at the destination coordinate, and then you will manually add the source location. Create links file from existing displacement links It is possible to create a links file from existing displacement links in ArcMap, regardless of whether the links were created manually or loaded from another file. Choose the Save Links File option from the Links submenu and you will be able to save the displacement link coordinates to a text file. Introduction to ArcGIS for ArcView and ArcInfo (II)

Error RMS Las localizaciones transformadas no concuerdan con con los puntos de control El error RMS indica la discrepancia Se pueden ver los RMS en una tabla asociada y eliminar asociaciones con un error RMS alto Punto de control de destino Fuente transformada por los puntos de control Error RMS Errors A root mean square error (RMS) describes the deviation that will occur when the transformation is applied to the input and the output coordinate systems. The error is determined using the least squares regression method. The transformation parameters are a best-fit between the source and destination control points. If you use the transformation parameters to transform the actual source control points, the transformed output locations won’t be an exact match to the true output control point locations. This is called the residual error; it is a measure of the fit between the true locations and the transformed locations of the output control points. This error is generated for each displacement link. Error RMS + e 2 n . . . 1 3 = Introduction to ArcGIS for ArcView and ArcInfo (II)

Rubbersheeting Ajusta las capas fuente para concordar con capas más exactas Los elementos se alargan, las lineas rectas se preservan Asociar identidades basadas en los elementos del lugar Ajustar todos los elementos ó bien un área delimitada Rubbersheeting Geometric distortions commonly occur in data. They may be introduced by imperfect registration in map compilation, lack of geodetic control in source data, or a variety of other causes. Rubbersheeting corrects flaws through the geometric adjustment of coordinates. Rubbersheeting stretches the features along the displacement links and holds features in place at the identity links. An identity link is a link whose source and destination coordinate are the same. Identity links act like nails to hold specific locations in place. After an adjustment, displacement links become identity links. Identity links can also be added manually with the Identity link tool on the Spatial Adjustment toolbar. At least one displacement link is required to perform the rubbersheeting adjustment. Rubbersheeting can be performed on a selected set of features to fit them to another set of features. For example, a lakeshore in one layer could be rubbersheeted to match a more accurate boundary in another layer. You can also perform rubbersheeting on all features in a feature class or feature dataset to another control dataset. That dataset could be a raster image as in the graphic above, a CAD drawing, locations specified interactively, coordinates in a text file, or by interactively entering coordinates into a table. Rubbersheeting (Linear, Natural Neighbor) - The adjustment is applied piecewise throughout the layer or throughout the selected features of the layer. No errors are calculated. Limited adjustment area The New Limit Adjustment Area tool allows you to draw a polygon shape around the features you want to adjust. This allows you to limit your adjustment to just the area covered by the added polygon. Features that are outside the adjustment area will not be adjusted.

Snap al borde Alinea elementos en capas adyacentes
La herramienta de Edge Snap añade asociaciones dentro de la tolerancia de snapping Opciones Métodos “smooth” o “line” Ajuste a los puntos medios de los links Utiliza atributos para definir el ajuste del borde Edge Snap Edge snap, also sometimes referred to as edge matching, uses rubber sheeting to match features along the edges of layers. If you are combining data from different sources, features may not align perfectly along the borders. The edge snap adjustment can be used to move the features in a source layer to match those in a target layer or to adjust to the midpoints of the links in which case features from both layers will be adjusted. When performing an edge snap, you can add displacement links manually, from a file, or automatically using the Edge Snap tool on the Spatial Adjustment toolbar. The Edge Snap tool allows you to drag a box over the source and target features to be edge matched. Links will be automatically added between source and target features that are within the current snapping tolerance set for the edit session. The Edge Snap adjustment method requires more property settings than other methods. You can set these property settings in the Edge Match panel of the Adjustment Properties dialog box accessed from the Options command on the Spatial Adjustment pull down menu. When using the Smooth edge snap method, vertices at the link source point are moved to the destination point. The remaining vertices are also moved, giving an overall smoothing effect. When using the Line edge snap method, only the vertices at the link source point are moved to the destination point. The remaining vertices on the feature remain unchanged. You have the option to specify one link per destination point and to prevent duplicate links. These settings can help you avoid creating unnecessary links. The Spatial Adjustment tool supports the ability to use attributes to enhance the edgematching process. Based on the Attribute Transfer Mapping dialog box, you have the option to match fields between the source and target layers and use common attributes to define the edgematch. This function can help ensure the accuracy of the edgematch. Edgematching (Smooth, Linear) Uses rubbersheeting to match features on the edit of layers. The adjustment only affects selected features. No errors are calculated. Introduction to ArcGIS for ArcView and ArcInfo (II)

Transferir atributos Transferencia interactiva de atributos entre elementos Hace juego con campos comúnes entre capas Ajustar la fuente y las capas destino Especificar los campos a transferir Opción de transferir la geometria SAN PABLO Click on source Click on destination 1 2 Transferring Attributes Attribute transfer is the transfer of attribute values from a target feature to a source feature based on user-defined field matching. Source and target features may reside in the the same feature class or different feature classes. Source and target feature geometry can differ. Geometry transfer is the altering of a target feature’s geometry based on the geometry of a source feature. This is achieved via the transference of shape values from source to target features as an attribute transfer. Geometry and attribute transfer are typically performed after ensuring that the target and source datasets are aligned using one of the spatial adjustment methods. Although both the target and source features are expected to be in close proximity, often overlapping, this is not a requirement for using the transfer tool.

Agregando datos espaciales
Copy and Paste Cargador de datos simples Cargador de objetos Comando Merge en el Geoprocessing Wizard Combinación de capas adyacentes Aggregating spatial data After data has been spatially adjusted, you will probably aggregate it with other data in your database. For example, after transforming street features for a new subdivision, you will add them into your street feature class. ArcGIS offers a number of tools and options for aggregating spatial data. Copy and Paste While in an editing session in ArcMap, you may copy selected features and paste them into the target layer using the Copy and Paste tools on the Standard toolbar. Simple Data Loader You can load features into an existing simple feature class (one that does not store custom or network features or is in a versioned geodatabase) using the Simple Data Loader in ArcCatalog. The wizard will allow you to specify a number of source tables and feature classes, provided their schema match. Object Loader If you are loading features into either a simple feature class or a feature class that contains custom or network features or is in a versioned geodatabase, you can use the Object Loader command. This command can be added to your ArcMap session from the Customize dialog. Merge Use the Merge command in the GeoProcessing Wizard in ArcMap. Merge is normally used to combine the features from adjacent layers together where the features do not overlap, and where the layers share the same attribute definitions. You can merge layers that overlap, however, the features are not unioned together to create new features with common boundaries or common line segments. Instead, both sets of features are just appended into the output layer, and the features will simply overlap. Introduction to ArcGIS for ArcView and ArcInfo (II)

You can dissolve either polygon or line feature classes, and the output will contain the same feature type as your input. Note that the Dissolve column will be the only user-defined attribute added to your output table. You can later join attributes from the original table, but be careful—it may not be appropriate to assign attributes from an individual feature to the group of features. Dissolving means you are throwing away data. For example, if you dissolve a feature class based on street names, the output feature class would have no user-added attributes other than those street names. Usually, you would not dissolve features permanently in the database. Instead, you would perform a dissolve temporarily for a particular project and, after you are done, archive the feature class or throw it away. Introduction to ArcGIS for ArcView and ArcInfo (II)

Agregando datos espaciales
Merge capas separadas en una Opciones para asignar atributos a una capa de salida Aggregating spatial data Use Merge when you want to combine two or more adjacent layers into one large layer that contains all their features. For example, you may want to merge highway data that you received as a series of separate tiles of data into one continuous layer. The merge operation will create a new shapefile or geodatabase feature class. Merge is normally used to combine the features from adjacent layers together where the features do not overlap, and where the layers share the same attribute definitions. You can merge layers that overlap; however, the features are not unioned together to create new features with common boundaries or common line segments. Instead, both sets of features are just appended into the output layer, and the features will simply overlap. Postprocessing If you save the output as a shapefile, the new features do not have their area, perimeter, or length calculated automatically. If the inputs had these values in their attribute tables, these attributes may be carried over into the output layer, but they will not be updated to reflect the new size of the features, so they should not be used as the basis for analysis. You can add these attributes to the output shapefile after using the Geoprocessing Wizard. See the online documentation on How to make field calculation for instructions on updating the size of features. If you save the output as a feature class inside the geodatabase, the size of the new features will be automatically calculated. Introduction to ArcGIS for ArcView and ArcInfo (II)

Clip de elementos Utilice un feature class para definir los bordes con otros Datos originales Clip del FC FC Final Clipping data Use Clip when you want to cut out a piece of one layer using one or more of the polygons in another layer as a cookie cutter. This is particularly useful for creating a new layer that contains a geographic subset of the features in another larger layer. For example, suppose you are studying the transportation needs of a particular county. You would like to work with a layer that contains only the roads or segments of roads that fall inside this county boundary, but all you have is a layer containing roads for the whole state. You can clip the roads in the state roads layer using the county polygon as the cookie cutter to create a new layer containing just the roads in the county. The layer that is having its features clipped can contain points, lines, or polygons. The cookie cutter or clip layer must contain polygon features. If you only want a subset of the features in this layer to be clipped, you can select them using any of the feature selection tools in ArcMap, before you start the Geoprocessing Wizard. You should then check the Use selected features only box on the second panel of the Wizard, just below where you specify this input layer. Introduction to ArcGIS for ArcView and ArcInfo (II)

Funciones del analisis espacial
Análisis de proximidad Localizando elementos basados en su distancia a otros Encontrando el elemento mas cercano Análisis de sobreposición Combinando elementos y atributos ¿Qué parcelas están a 50 metros de la carretera Spatial analysis functions For some types of spatial analysis, you can use the Select by Location query to find features in relation to other features. For example, finding shopping malls close to your office would involve a simple Select by Location query. Other spatial analysis operations require more advanced tools, such as those found in the Geoprocessing Wizard. For instance, if you wanted to find the exact land area in layer A contained within the extent of layer B, you would need to perform a union or intersection operation. The spatial analysis functions are divided into two main sections: proximity analysis and overlay analysis.

Buffering Una herramienta de análisis de distancia para elementos puntuales, lineas y áreas Crea un nuevo polígono representando una distancia específica Responde preguntas basandose en la proximidad Buffering A buffer is a polygon zone around some geographic feature or set of features. You can use buffer zones to find features contained inside or that fall outside of your specified distance. For example, you could create a buffer representing a one-mile radius from an earthquake fault line and find out how many major shopping malls are within this area. With buffers, you could quickly determine which malls are in the greatest danger of being damaged in an earthquake. Create new shapes You create buffer zones by specifying a distance. You can use the same distance for every feature in the layer or use a numeric attribute to specify different distances for each feature. The output of the buffer operation is either a new polygon shapefile or geodatabase feature class. Answer questions based on proximity You can use buffers to select features from other layers in your view. In addition to finding shopping malls near fault lines, you can apply buffers to zoning or real estate problems. For instance, in some parts of Texas, there are ordinances prohibiting liquor from being sold within one mile of an elementary school. You could buffer the schools to create a new set of polygons representing the one-mile distance and then do a selection to make sure no liquor stores fall within the ‘no liquor’ zone.

El Buffer Wizard 1 Escoja los elementos 2 Escoja las distancias The Buffer Wizard The Buffer Wizard allows you to create a buffer as graphics in the display, as new polygon features in an existing editable layer, or as a new shapefile or geodatabase feature class. The Wizard’s dialogs guide you through choosing the features to be buffered, choosing the buffer distances, and choosing the output. Choose the features The first Buffer Wizard dialog prompts you for the type of feature you want to buffer. This can be a graphic in your view, all features in a layer, or only selected features in a layer. Choose the distances The second dialog prompts you for the buffer distance. You can choose a specified distance to buffer all features, use a numeric field’s attribute value to buffer each feature by a different distance, or create multiple concentric buffer zones of a specified distance. You choose the buffer’s distance units; they can be different from the units set in the Data Frame Properties. Choose the output The final dialog asks if you want to dissolve the borders between adjacent buffer polygons and how you want the output formatted. If you are not concerned with buffers around individual features, you should dissolve the borders between adjacent areas. Note: If you dissolve adjacent borders, all buffer polygons will be grouped into one record in the feature class table.

Análisis de sobreposición y geoprocesamiento
Punto-en-polígono Linea-en-polígono Es diferente de seleccionar por ubicación Polígono-en-polígono Capa de entrada Capa de sobreposición Point-in-polygon overlay To find which point falls inside which polygon, use the point-in-polygon analysis. For example, suppose you want to know how many grocery stores are inside each census tract. The new grocery store layer will have census tract attributes. You can query the store to find out which census tract it falls within. Line-in-polygon overlay To find the common areas between a line layer and a polygon layer, use line-in-polygon analysis. If you have a river layer and a parcels layer, for example, you could find out which river falls inside each parcel and exactly how much river is contained in each parcel. The output is much more accurate than a Select by Location query because input features are physically split by the overlay layer. Polygon-on-polygon overlay For studying common areas between the two layers, use polygon-on-polygon overlay analysis. For example, if your first layer represents parcels and your second layer represents flood zones, you can find the flood risk for each parcel and the exact area of flood zone contained within each parcel.

Unión e Intersección en el Geoprocessing Wizard Lineas ó poligonos Combinar atributos Extensión limitada Intersección Unión Polígonos Combinar atributos Extensión completa Overlay analysis functions The Geoprocessing Wizard accomplishes overlay analysis through unioning and intersecting layers. Intersect Intersect combines features from two layers that share the same geographic extent into a third layer. You can intersect line or polygon layers with another polygon layer. The output layer will contain the same feature type you input as well as both input sets of attribute fields. Union Union combines features from two polygon layers to create a new polygon layer. The new layer will contain both sets of input attribute fields. Introduction to ArcGIS for ArcView and ArcInfo (II)

Unión Crea una nueva capa de la geometría combinada de dos capas de entrada Tanto la capa de entrada como la sobrepuesta deben de ser de poligonos Entrada, dos capas de vegetación Salida + Union The union operation allows you to integrate two layers and create a new layer that contains all the features from both. For example, suppose you were interested in finding out the relationship between vegetation and underlying soil characteristics. You could union the vegetation and soil layers to create a new layer that now has the polygon boundaries and attributes for both vegetation and soils. The vegetation shape geometry is split by the soil polygons and will inherit the soil attributes. Once you have this information, you can query the vegetation areas to see which ones have a certain soil characteristic. You could make a chart showing the relationship between vegetation type and soil class. Technically speaking Union computes the geometric combination of two layers and adds the new layer to your ArcMap display. Both the input and overlay layers must be polygons. All input features that cross the polygon borders of the overlay layer will be split and written to a new shape in the new layer. The output shapefile’s features will also be polygons that inherit the attributes from both input layers. Recalculating area, perimeter, and length for shapefiles When you perform a union operation, the geometric attributes of a new shapefile are not automatically updated. See the online help for how to update the area and length field values for shapefiles. Geometric attributes for geodatabase feature classes will be automatically updated.

Suppose you want to determine the soil characteristics under the existing roads in your study area. You could use the Geoprocessing Wizard to intersect the soils with the roads to create a new layer where each road is clipped to the soil polygon boundary and inherits the soil’s attributes. You would be able to find out which roads were built on soils susceptible to erosion. You could then figure out how to prevent road damage after heavy rainfall. Technically speaking Intersect computes the geometric intersection of two layers. The input layers can be lines or polygons, but the intersect (overlay) layer must be polygons. All input features that cross internal polygon borders will be split and written to a new shape in the new layer. Any features in the input layer that are not spatially coincident with the polygon features will be ignored. The output feature class will be of the same geometric type as the input layer features and will inherit the attributes of both input layers. Note: If you want to do a point-in-polygon overlay, you have to do a spatial join. 4 Poligonos Sobreposición Introduction to ArcGIS for ArcView and ArcInfo (II)

Join espacial Join basado en una localización espacial
Utilizado para análisis de punto-en-poligono Encuentra el elemento más cercano Adiciona atributos y calcula la distancia Buenas localizaciones de tipos de suelo Spatial join In earlier lessons, you joined tables based on common attribute values. You can also join tables based on their spatial locations. A join in this manner allows you to find out which features fall within a polygon, which features intersect, and what are the closest features between two layers. Like joining two tables by matching attribute values in a field, a spatial join appends the attributes of one layer to another. You can then use the additional information to query your data in new ways. A spatial join creates a new layer containing both sets of attributes.

El proceso analítico ¿Qué pregunta esta tratando de resolverse?
¿Qué criterios están involucrados? REGIS database ¿Cual es la mejor localización para un establecer parque? Defining the project scenario The first step to successfully completing an analysis is to clearly define the question to be answered. See if you can put the scope of the analysis into one or two sentences. If you can do this, then the data needs and the process to follow will become much more obvious. After you have defined the question, you can determine what criteria will be used to answer it. In the example above, if you are looking for a location to build an amusement park, you will look for areas that meet certain criteria.

The criteria will usually describe the data and attributes needed. You should also determine if any preprocessing of the data is going to be necessary before the analysis is performed. Often, you will need to convert data from one format to another that is more suitable for a specific type of analysis. For example, if you need to perform a polygon overlay on data in a geodatabase, you might convert the data to coverage format first, perform the overlay, then convert the resulting coverage back into the geodatabase. In this step, you will also need to determine if the attributes you need are available on an independent table. You may have to create a relationship class or perform a data join to access the attributes you need. Introduction to ArcGIS for ArcView and ArcInfo (II)

Try to choose the method that answers the question in the most efficient manner. Finally, it is highly recommended that you chart out the proposed analytical process. This will encourage you to think the problem through from start to finish, and you can save a lot of trouble in the long run. Introduction to ArcGIS for ArcView and ArcInfo (II)
