Land use and land cover change have been among the most important perceptible changes taking place around us. Human interventions in natural systems have resulted in large changes in vegetation, composition and distribution patterns. Changes in land use and hence in vegetation cover, due to climatic change and human activity changes the area constantly. Thus, there is a need for spatial and temporal characterization of vegetation cover at different scales. Satellite remote sensing provides detailed information regarding the spatial distribution and extent of land use changes in the landscape. This study encompasses the quantitative analysis of land use and land cover change in South Chennai using remote sensing technologies. SOI toposheet 1970, Landsat TM (Thematic Mapper) satellite images for year 1991 and 2006 have been utilised to quantify the changes for last three decades. The study concludes that built-up area is increased as 6.8%, 14.7% and 16.1% with a decrease of Forest cover from 20.3%, 16.3% to 15.3%.
