ahead-of-time workflow

The ahead-of-time workflow, also known as preplanned workflow, is a development pattern for building offline applications where offline map areas in a web map are used by the offline app. The offline map areas are defined by the web map author in the portal to be packaged as an offline map. Once the offline map areas are defined by the web map author, ArcGIS Online or ArcGIS Enterprise will generate an offline map for the specified area which is ready for download when connected to a network. Once downloaded, the offline map can be used without network connectivity.
