Create and use a raster layer made from a local raster file.
Use case
Rasters can be digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps. An end-user will frequently need to import raster files acquired through various data-collection methods 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 file and displayed in the map view.
How it works
Create a Raster from a raster file.
Create a RasterLayer from the raster.
Add it as an operational layer with Map.OperationalLayers.Add(layer).
