ArcGIS Runtime SDK for Java

Raster Layer File

Demonstrates how to create and use a raster layer made from a local raster file.

How it works

To add a RasterLayer as an operational layer from a local raster file:

  1. Create a Raster from a raster file.
  2. Create a raster layer from the raster.
  3. Add it as an operational layer with map.getOperationalLayers().add(rasterLayer).
