Crear el servicio de descarga del dataset predefinido de INSPIRE—ArcGIS for INSPIRE

Introducir los archivos para el Servicio de descarga de datasets predefinidos de INSPIRE

Puedes crear un Servicio de descarga de datasets predefinidos de INSPIRE basado en la implementación de la guía técnica de ATOM para la implementación de los servicios de descarga de INSPIRE de la versión 3.1.

Para habilitar el servicio de descarga de datasets predefinidos de INSPIRE, se necesitan los siguientes archivos de entrada:

Archivo ATOM del servicio: archivo del nivel más alto del servicio ATOM que contiene los vínculos a los archivos del dataset de ATOM. Los vínculos a cada archivo de dataset ATOM son entradas separadas. A continuación, se muestra un ejemplo.
Archivo de ATOM del dataset: este archivo contiene vínculos a los datasets. Puede incluir varias entradas para el dataset y cada entrada representa una combinación del CRS y el formato de datos para el dataset. A continuación, se muestra un ejemplo.
Archivo descriptor de OpenSearch: este archivo define las operaciones de OpenSearch para el servicio de descarga de INSPIRE basado en ATOM que incluye: q, para la búsqueda de parámetros en texto libre, describe el dataset espacial y la operación de obtención del dataset. A continuación, se muestra un ejemplo.

Los archivos de entrada deben estar almacenados en una carpeta accesible. El usuario que habilite y configure el servicio de descarga de datasets predefinidos de INSPIRE debe disponer de permisos de acceso de escritura en la carpeta de salida de ArcGIS for Server (por ejemplo, C:\arcgisserver\directories\arcgisforinspire).

Es posible crear más de un archivo de servicio y de dataset ATOM para admitir más de un idioma en un solo servicio. Los vínculos mutuos entre estos archivos deben estar rellenados correctamente para que se devuelva el contenido correcto en las operaciones que dependen del idioma. Consulte la guía técnica para la implementación de los servicios de descarga que está disponible en el sitio web de INSPIRE para obtener descripciones detalladas sobre las especificaciones de idioma.

Cómo se crean los servicios de descarga de datasets predefinidos de INSPIRE

El servicio de descarga de datasets predefinidos de INSPIRE se puede habilitar en cualquier servicio de mapas. Se recomienda habilitarlo junto con un servicio de visualización o descarga de entidades de INSPIRE. Siga los pasos a continuación:

Inicie ArcCatalog.
Selecciona el servicio desees agregar al servicio de descarga de datasets predefinidos de INSPIRE.
Haz clic con el botón derecho del ratón en el servicio y, a continuación, en Propiedades del servicio.
Accede a la sección Capacidades y habilita el servicio de descarga de datasets predefinidos de INSPIRE.
Haz clic en las capacidades del Servicio de descarga de datasets predefinidos de INSPIRE.
Haz clic en Elegir archivo ATOM del servicio de descarga, selecciona el archivo ATOM del servicio y haz clic en Abrir.
Haz clic en Aceptar. Si se produce algún error de validación en el archivo de entrada, repite estos pasos hasta que se corrija el error.

Una vez que se reinicia el servicio, el servicio de descarga de datasets predefinidos de INSPIRE configurado queda expuesto al directorio REST de ArcGIS Server (por ejemplo http://servername:6080/arcgis/rest/services/<nombre_del_servicio>/MapServer/exts/InspirePredefinedDatasetDownload).

En esta sección se proporcionan archivos de ejemplo ATOM para servicios y datasets, y de descriptores de OpenSearch.
