Urban expansion has been creating an alarming situation in all countries of the world. High rate of urban population growth has led to serious land use problems such as loss of agricultural land, unauthorized urban sprawl, high land values, pollution, poverty and social unrest making urban governance a difficult task to maintain healthy urban environment. In the emerging scenario it is essential to have up-to-date information in existing land use information system. In the recent times, remote sensing and geographical information system (GIS) are very valuable and advantageous in providing current land use information. The present study highlights significance of remote sensing in the detection of urban land use changes for the time periods (1989 and 2006) using satellite imageries from IRS-P6, LISS III, IRS-P5, PAN and LANDSAT TM. . The satellite imageries IRS-P6, LISS III and IRS-P5, PAN for two consecutive dates were merged to produce a single merged image of two satellite imageries. These merged image and LANDSAT TM were further subjected to supervised classification for change detection. The result of change detection shows that the significant decrease of agriculture area and increase in settlement area from year1989 to year 2006. The spatial information from the remote sensing satellites plays a vital role in analysis of changing land use/land cover pattern.
