Ein Kachelpaket kann nicht aus den World Imagery-Services exportiert werden

Beschreibung

In some instances, an attempt to export or extract a tile package from the World Imagery (for Export) service fails.

Ursache

The World Imagery (for Export) map service is designed to support exporting small volumes of basemap tiles for offline use, according to the access and use constraints. However, the size of the basemap that is exported with the web map can reach a limit that can cause the download to fail. Basemap services are configured by default to prevent the export of more than 100,000 tiles. Refer to Problem: Unable to download a map for offline use in Collector for ArcGIS for more information.

Note:
Sometimes, the failure may be due to service disruptions when servers are experiencing downtime. This issue is only temporary. When the issue is resolved, and the service resumes operating normally, access the services again. The status information for ArcGIS Online services can be viewed at ArcGIS Online Health Dashboard.
