Abstract
In this paper an attempt has been made to mapping the land use and land cover categories of Arjuna River basin using the Remote Sensing techniques. The study area, which is located in the southern part of Tamil Nadu. The basin covers an area of about 1687 sq.km. The basin has basin subjected to different kinds of environmental degradation by both man and nature. The analysis will help for better land management for sustainable development. The analysis is based on primary, secondary and ground data. The primary remote sensing data are included IRS (LISS I, II). The interpretation key of the NRSA (1985) has been used for this purpose. The advantage of the remote sensing data over the conventional statistical data is due to its more reliability, accuracy, time saving and cost effective. The present land use / land cover pattern indicates as follow, built land, agricultural land, forest, waste lands and water bodies.
