ee.Terrain.hillshade

    • The ee.Terrain.hillshade function computes a simple hillshade from a digital elevation model (DEM) input.

    • It returns an Image and takes an elevation image, illumination azimuth (default 270 degrees), and illumination elevation (default 45 degrees) as arguments.

    • Examples in both JavaScript (Code Editor) and Python (Colab) demonstrate its usage.
