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.

Apply Colormaps, Lighting, and Shaded Relief
Shade and Light Terrain Maps
- Add Light Source to Terrain Map
Add a light source to a terrain map, then set surface reflectance properties.
- Surface Relief Shading
A shaded-relief map models illumination over a surface to highlight the texture of the surface.
- Colored Surface Shaded Relief
This example shows how to illuminate surface texture over colored elevation data using shaded relief computations.
- Relief Mapping with Light Objects
This example shows how to illuminate surface texture over colored elevation data using a light source.
Drape Data on Elevation Maps
- Drape Data on Elevation Maps
You can drape satellite data over a grid of elevations in order to see the topography of the surface.
- Drape Geoid Heights over Topography
This example shows how to drape the figure of the Earth, shown as an attribute (color) data grid, on topographic relief.
