Ejemplo: Publicar un servicio de geoprocesamiento a partir del resultado de un modelo

Esta secuencia de comandos de Phyton ejecuta un modelo y publica el resultado en ArcGIS Server en forma de servicio de geoprocesamiento.

La secuencia de comandos construye primero unas capas de entidades y ejecuta el modelo Tarea de extracción de datos de la caja de herramientas Herramientas de servidor. Si la ubicación de la capa de entidades no está registrada en ArcGIS Server, la secuencia de comandos llama a arcpy.AddDataStoreItem para registrar la base de datos o la carpeta. A continuación, la secuencia de comandos invoca arcpy.CreateGPSDDraft para crear un borrador de un archivo de definición de servicio (SD) a partir del resultado del modelo.

Si no se detectan errores en el análisis del borrador del SD, la secuencia de comandos continúa con la publicación del servicio.
