Relief Maps

Create 3-D relief maps, drape data over terrain, customize shading and lighting

A relief map illustrates terrain or other surface texture by using shading and lighting. Use these functions to create relief maps from gridded data, adjust shading and lighting, exaggerate terrain, and apply colormaps. You can also drape data over elevation maps.
