Geo-morphological mapping for land resource assessment study of north western part of Bhopal using remote sensing and GIS technique

Abstract

Geomorphological mapping, was carried out using IRS-P6 LISS III data of about 713 sq. km area of north western part of Bhopal district, Madhya Pradesh. Present study attempts to identify and delineate geomorphic features based on visual image interpretation technique from digital data. Geomorphic Landforms are interpreted on the basis of interpretation elements like tone, texture, size, shape, color etc. and extract the specific information from the false color composition LISS III sensor images. Geomorphological units are classified on the basis of differential erosion processes. Geomorphic unit namely pediplains, pediments, butte, mesa, cuesta, hogback, plateau, plateau remnant and residual hills mapped using IRS P6 LISS III satellite imagery using visual interpretation technique along with selected field checks. Remote Sensing and GIS offers detecting and analyzing time and cost effective way to fulfill the goal. Limited field transverses were undertaken to verify the interpretation.
