Abstract: Urbanization is a dynamic process involving all sides’ expansion of urban regions. This rapid expansion is due to rise in population and economic growth thereby causing a change in land use patterns as well as an increase in demands and destruction of natural resources. Land Use is a key element in temporal studies of urban imagery. Land-use change is the main driving force for the Social and industrial development which affects largely on local ecology, hydrology and environment and also globally. This change has been studied using Remote Sensing and GIS technologies for a rapidly growing place namely Bangalore Urban district. Remote sensing data enables the synoptic monitoring and visualization of urban growth patterns. The present work emphasizes on the major land use changes and urban sprawl in this region thereby determining the urban patches and would be employed to estimate the change in surface runoff, flood phenomenon and natural resources (Water bodies and Vegetation). The satellite imageries of 2006, 2011 and 2016 are taken and classified into 5 different classes like Water, Agricultural (Culturable wastelands and Crop lands), Built ups, Barren and Vegetation by Maximum Likelihood Classification. The results indicate that the region is expanding with the change of vegetation from 22.16 percent to 7.53 percent into Built-up areas from 18.12 percent to 25.28 percent out of the total area during the study period.
