Vector
Metadata for a local cache of vector map tiles that can be used to create a layer. Local tile caches are ideal for providing basemaps or less frequently changing contextual layers, where network access is limited or non-existent. They can be created and downloaded onto a device by using an ExportVectorTilesJob, or alternatively can be provisioned directly to local storage. Currently the only supported type of cache is:
Vector tile package (.vtpk) - a map and the tile cache of the data contained within it, packaged into one convenient, portable file, ideal for offline sharing or complete map documents in a disconnected environment or via a portal.
A VectorTileCache is often used as a basemap, but can also be used to create an ArcGISVectorTiledLayer that is added to a map as an operational layer.
