Use case

GeoPackages are designed to simplify file management and transfer. They can store raster files (as well as other types of data). An end-user wishing to transfer rasters from ArcGIS Pro or between runtime apps, might need to import raster files from GeoPackages into their map to view and analyze the data.

How to use the sample

When the sample starts, a raster will be loaded from a GeoPackage and displayed in the map view.

How it works

Create and load a GeoPackage, specifying the path to the local .gpkg file.
When it is done loading, get the GeoPackageRasters from the geopackage.
Construct a RasterLayer with the geopackage raster you want to use.
Add the raster layer to the map.
