Remote Sensing studies on Land use / Land cover of Peddavanka Watershed, Anantapur District, Andhra Pradesh

Abstract

Land use / land cover studies have been carried out by using remote sensing data of Peddavanka Watershed, Anantapur District, Andhra Pradesh. Peddavanka, a tributary to river Pennar, rises from Mutchukota hills of Erramalai hill ranges flows southerly and joins the Pennar River near Tadipatri of Anantapur district. This originates in the southern part of Kurnool district and drains through north-eastern part of Anantapur district covering an area of about 298 Km², located in the Survey of India Toposheet numbers 57 E/16, F/13, J/1, and I/4 on a scale of 1:50,000. The study area lies between Latitudes 14^o55'24" - 15^o12'50" N   and Longitudes 77^o51'20" - 78^o03'26" E. The present classification is done with the help of IRS-1C Geo-coded imageries on 1:50,000 scale by visual interpretation techniques considering the elements of image interpretation such as shape, size, tone, texture, pattern and association, the satellite images were interpreted to delineate various land use / land cover categories.
