ANALYSIS OF RELIEF CHARACTERISTICS USING DIGITAL ELEVATION MODEL: A CASE OF DUMKA UPLAND, JHARKHAND, INDIA.

Sayan Choudhary, Vibhash Chandra Jha

Abstract


Analysis of relief characteristics is an important part of terrain analysis. Morphometric analysis based on geospatial technology has several advantages over manual methods based on conventional data bases such as topographical maps. Firstly, being fully automated process, it has very less scope for subjectivity, omission or commission errors. Secondly, it is much easier to acquire geospatial data than topographical maps. There are various authoritative sources that provide free geospatial data on global and regional scales. Hence, it is much easier to work on global or regional scales cutting across international boundaries. In this paper ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) digital elevation model (DEM) has been used for the analysis of relief characteristics.
