Raster layer (file)

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

1. Create a Raster from a raster file.
2. Create a RasterLayer from the raster.
3. Add it as an operational layer with Map.OperationalLayers.Add(layer).
