3 Empecemos por el nombre… Aparición: año 1999. Geographic Data Access Service and the Geolinking Service. Geographic Linkage Service (GLS). Table Joining Service (TJS). Mismos fundamentos. Introducción mejoras en interoperabilidad y testing. Año 2004: OGC. Año 2009: Request for comments de OGC. Actualidad/presente: estándar OGC.

4 Unir Attribute Data con su Framework Data. Publicación de información recogida en tablas y relativa a figuras geográficas, así como su unión con las figuras geográficas correspondientes. Describir e intercambiar datos que contienen información de objetos geográficos. Método simple para encontrar, acceder y usar attribute data de múltiples fuentes, completar bases de datos, realizar análisis y crear mapas. En definitiva, permite intercambiar información de atributos geográficos entre diferentes servicios web. ¿Qué es TJS?

5 Identificador Intercambiar, examinar y analizar datos GetCapabilites Data access Data joining GDAS Necesidad de TJS Simple y potente. Estándar HTTP y XML. Fácil gestión de datos distribuidos en cualquier lugar en Internet. Acceso rápido y fiable a la información. flexibilidad con la seguridad. Facilidad para encontrar datos.

6 Aplicaciones TJS Apoyo a otros servicios OGC: Es complementario con WMS, WFS y WPS. Ej: Extracción y unión de datos + GDAS ser manipulados como parte de una cadena de servicios, como el WPS: realizar cálculos, comparaciones u otros análisis de datos en formato GDAS antes del JoinData. Crear mapas en la Web: crear capas WMS "on-the-fly"(sobre la marcha): la creación dinámica de capas del Web Map Service (WMS). Modelado. Actualización de datos: replicar las bases de datos a través de Internet. Interoperabilidad TJS es incluso útil cuando Atributte Data y Framework Data están almacenados en el mismo servidor.

7 Simple de entender e implementar. Ligero. Altamente escalable. Multi-propósito. No es ambiguo. Su contenido en metadatos posibilita generar automáticamente, tablas, gráficos, documentación, mapas y leyendas de un mismo grupo de datos. Soporta la identificación de valores nulos contenidos en la base de datos. Soporta la unión de los datos con su geometría en relaciones N:1 o N:N. Especifica la tipología de atributo. GDAS Geographic Data Attribute Set. Formato XML usado por este servicio para el intercambio del Attribute Data. Fin: empaquetar la información de atributos con sus metadatos para transmitirlo todo junto a través de la red. Ventajas Conocer exactamente lo que contiene la base de datos así como a qué marco espacial hace referencia. Producido en su totalidad como respuesta a la operación GetData del TJS. Todas las operaciones de petición y repuesta del TJS están sustentadas por partes de GDAS.

8 Usos de GDAS Apoyar la unión de Atributte data con su Framework Data para los servicios WMS y WFS. Respuesta a una petición de GetFeatureInfo del WMS : INFO_FORMAT=text/xml; subtype=gdas/1.0. Usado/generado como entrada o salida de un modelo espacial. Documento GDAS + referencia XSL generar páginas web/suministrar entrada a modelos o servicios de generación automática de mapas. Geographic Data Attribute Set (GDAS) encoding format: … [spatial framewok metadata]... [attribute dataset metadata]... [attribute metadata]... [attribute data]
