DEM

DEM
DEM, or digital evaluation model, is an image that shows the elevation of the earths surface which can be used to create digital models and representations of maps and 3D images. Often times remotes sensing is used to gather data to build such images. This example shows the 3D graphics for the GIS and the multilayer map that uses transparencies to signify the important characteristics and trends.
