A Digital Elevation Model is a type of map that is used to represent only the height information of surfaces. This map completely abandons any further information about the terrain. There are many uses for a Digital Elevation Maps. Models representing water flow, terrain analysis, line-of-sight analysis, base mapping and precision farming and forestry are just a few examples of these uses.
This particular Digital Elevation Model displays the Japanese city of Isehara, Kanagawa Prefecture and its surrounding areas. This map, like many DEM maps puts more emphasis on the vertical scale than the horizontal scale to enhance the differences in the terrain's height.
