The Satellite Derived Digital Elevation Models of Mikir Hills, Karbi Anglong, Assam, India

Abstract

Digital Elevation Model (DEM) data are used for geological analysis when other data are not accessible for morphology and structure identification. DEM data due to its quick availability and less expense is used for enhancing accuracy. Three-dimensional (3D) inputs are added to the twodimensional (2D) data for a better interpretation of topography, relief, and geology. The present paper explicates the potential of DEM for modeling of Mikir structural hills of Assam -a highly dissected and geologically important region generated from Shuttle Radar Topography Mission (SRTM) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images.
