| Summary: | Rapid urbanization has significant impact on resources and urban environment. With increased
availability and improved quality of multi-spatial and multi-temporal remote sensing data, it is
now possible to detect urban changes in a timely and cost-effective way. This study aims to
quantify changes in urban area of Salem revenue division, Tamil nadu located in India, using
Land sat and IRS-LISS-III image. Urban changes were detected by satellite images of Land sat
MSS in 1973, Land sat and IRS-LIS-III in 2010 using a geographic information system (GIS).
The settlement area has grown 2.07 times during the past 37 years as a result of industrial
development, population growth and permanent migration was the main driving forces for
settlement area expansion. According to the results, the extent of urban areas 69.899sqkm and
144.97sqkm in the years 1973 and 2010 respectively.
