A height map is a grayscale texture used as a displacement map to define the topography of the polygons.
Usually the brighter pixels make higher elevations, and the darker pixels make lower elevations, and 50% gray pixels make no change. Often the alpha channel of an object's texture is used for the height map. Landscapes often use height maps.
