Abstract

The present study has been conducted to analysis the land use and land cover of Mysore-Mandya corridor region between the years 1991 and 2014. The study has been done using remote sensing data and GIS techniques. The necessary satellite images (1991, 2001 and 2014) have been obtained from the United States of Geological Survey website and the GIS analysis has been done in ERDAS. The downloaded satellite has been corrected atmospherically and radio-metrically using ATCOR module in ERDAS. After preparing the corrected base imagery, supervised image classification has been carried out using maximum livelihood algorithm. To prove the accuracy of the classification result, the error matrix and Kappa index have been applied from which the classification accuracy was 95.91 per cent. The spatial extension LULC analysis showed that, the built-up land use has been increasing continuously while other land uses have been decreasing. The land transit analysis depicts the high conversion of vegetation and waste land into built-up during the study period. Finally, decadal wise comparison shows that, during the second period of study (2001 � 2014) the intensity of conversion is higher than the first period (1991 � 2001) for the land use categories.
