Portal for ArcGIS se entrega preconfigurado con un conjunto de mapas base de ArcGIS Online. Estos mapas base no son compatibles con los flujos de trabajo sin conexión. Por ejemplo, no puede dejar estos mapas base preconfigurados sin conexión en Collector for ArcGIS.
La siguiente secuencia de comandos de python toma los mapas base predeterminados de ArcGIS Online y los agrega como elementos de mapa en el portal. Los elementos de mapa de los mapas base se pueden dejar sin conexión para usarlos en flujos de trabajo sin conexión. Para ejecutar la secuencia de comandos, debe proporcionar las credenciales de su cuenta de ArcGIS Online.
Debe especificar la siguiente información cuando ejecute la secuencia de comandos:
- Dirección URL utilizada para acceder a Portal for ArcGIS. Puede ser la dirección URL de ArcGIS Web Adaptor, por ejemplo, https://webadaptor.domain.com/arcgis o la dirección URL de la máquina que aloja el portal, por ejemplo, https://portal.domain.com:7443/arcgis. Debe incluir el nombre de dominio completo del equipo cuando especifique la URL.
- Nombre de usuario y contraseña de una cuenta en el portal.
- Nombre de una carpeta en la que se crearán nuevos elementos de mapa. Si no se proporciona, los elementos de mapa se crean en la carpeta raíz.
- Nombre de usuario y contraseña de una cuenta de ArcGIS Online. Esta secuencia de comandos integrará sus credenciales de ArcGIS Online en los nuevos elementos de mapa, lo que habilita las funciones sin conexión de los mapas base.
El ejemplo siguiente crea un conjunto de mapas base en la carpeta raíz. Los mapas base incluyen sus credenciales de ArcGIS Online para que aplicaciones como Collector for ArcGIS puedan usarlas en los flujos de trabajo sin conexión.
