Spatial analysis of relief characteristics in Kondagaon District (Chattishgarh, India) – A study based on remote sensing and Geographic Information system

A study is carried out to evaluate the terrain characteristics at micro level using high resolution satellite data. ASTER GDEM satellite data is used to extract the relief characteristics of the study area. Morphometric characteristics of the study area are extracted using 5km² grid area. The highest slope in this region is recorded as 52.13 degree. A 30 meters contour interval map was generated and high average relief is discernable in north-eastern and south-western part of the study sites (>676.81 meters). The relative relief in the study site is ranged from 52.75 – 374.95 meters. Very high dissection index (>0.27) is well marked northern and southern part of the study site. Higher drainage density was found in the north-eastern, central and southern part of the study site, while the lower drainage density (<0.20 per km²) was delineated eastern and northwest part. The information obtained in the present research may aid in agricultural development in the study area.
