AN ANALYSIS ON LAND USE/LAND COVER MAPPING USING REMOTE SENSING AND GIS TECHNIQUES – A CASE STUDY

S. Jagadeesh Babu, K. V. Swamy

Abstract :

Remote Sensing as a direct adjunct to field, recently playing an important role in the study and assess the natural resource in any part of the world. Anthropogenic changes in land use and land cover and land use are often assumed to be identical, they are rather quite different. Land cover may be defined as the biophysical earth surface, while land use is often shaped by human, socio–economic and political influences on the land. The geospatial technology of RS and GIS holds the potential for timely and cost –effective assessment of natural resources. The techniques have been used extensively in the tropics for generating valuable information on forest cover, vegetation type and land use changes. Therefore, we have used RS and GIS to study land use land cover changes in and around. Under this study three thematic maps such as location map, drainage map and land use / land cover maps were prepared. The land use and land cover analysis on the study area has been attempted based on thematic mapping of the area consisting of built–up land, cultivated land, water bodies, forest and uncultivated land using the satellite image. The research concludes that there is a rapid expansion of built–up area. Land use and land cover information, when used along with information on other natural resources, like water, soil, hydro–geomorphology, etc. will help in the optimal land use planning at the macro and micro level.
