The digital elevation model in GIS software is the digital representation of surface elevation of a particular land with reference to the fixed datum or level.
DEM represents the topographic surface which is used for extracting terrain parameters for geomorphology, modeling water flow for hydrology, or mass movement, and other levels related works.
