GEOINFORMATICS APPLICATION ON LAND USE/ LAND COVER CLASSIFICATION ANALYSIS IN KOLLEGALA TALUK OF CHAMARAJANAGARA DISTRICT, KARNATAKA, INDIA

Abstract

Land resources planning and its development is an important issue in the present era. Major changes in any part of earth’s surfaces will significantly influences the environmental factors such as atmosphere, soil, topography, vegetation, underlying geology, hydrology, plant & animal population. The present aim is to classify the Land Use/ Land Cover (LU/LC) categories based on NRSC’ standards (1995) to increase land productivity, restoration of soil degradation, reclamation of wastelands and increase the environmental qualities. An attempt have been made to evaluate the level-I, level-II and level-III LU/LC classification system using IRS-1D PAN+LISS-III through GIS. The classification accuracy is found to be more in case of digital technique as compared to that of visual technique in terms of area statistics. The final results demonstrate the accurate mapping of classified LU/LC categories for implementation, management, mapping, measurement and monitoring through geoinformatics techniques.
