- W2936242597 abstract "Urbanization is a global phenomenon, but the rate of urban growth is relatively faster in developing countries like India. The drastic urban growth in India has resulted in a huge loss of agricultural land and water bodies, which needs to be quantified for future planning and development. In this context, the present study depicts a combined approach of remote sensing and GIS techniques for delineating the land use/land cover dynamics of Salem district of Tamil Nadu in South India. The Landsat Thematic Mapper data of the years 1992, 2001 and 2010 and Operational Land Imager data of the year 2015 were used to assess the changes in the land use and land cover. The supervised classification technique-maximum likelihood algorithm, was used in this study to classify the remote sensing data. The results indicate that the deciduous forests, croplands, cultivation and plantation lands and water bodies have decreased from 1992 to 2015 by about 398 km2, 250 km2, 45 km2 and 16 km2, respectively. At the same time, evergreen and semi-evergreen forests, built-up lands and mines and barren lands have increased by about 288 km2, 293 km2 and 128 km2, respectively. The accuracy of the present study has been assessed by using error matrix method. The overall accuracy of the land use/land cover classification of the years 1992, 2001, 2010 and 2015 is about 88%, 95%, 93% and 93%, respectively. The study showed that the combination of remote sensing and GIS is an efficient tool to detect the changes in land use/land cover. The land use/land cover information thus obtained can be used to the decision-makers for effective land use planning and management." @default.
