Digital Elevation Model (DEM) provides the third-dimension information of the terrain relief. In the present-day scenario, DEM became the most inevitable part of Remote Sensing and Geographic Information System (GIS) because of its wide capabilities in extracting features of ground profile. DEM is playing a prominent role in various fields like topographic mapping, 3D simulations, runoff modelling, disaster risk management etc. Fine or higher resolution DEMs are capable of depicting even the com
