After the visual interpretation of Satellite imageries direct field checks have been made. The primary data were acquired from the LANDSAT satellite imagery. The supplementary data were generated from the survey of India SOI topographical maps. A base map was prepared using survey of India toposheets having the index of numbers, 58M/4, 7, 8, 11, 12 and 58N/1 on a scale of 1:50,000 as an understanding of this study. Totally 6 toposheets have covered the study area. The geographical features like major road, railway, and drainage system, and elevation information, nature of River, tank, settlements and relevant information were incorporated in the base map. Arc GIS used to integrate the available data sources. LANDSAT MSS (1976), IRS P6-LISS III (2010) satellite data the urban land use classification were attempted. The classification followed here is based on unsupervised classification and interpretation; the data interpreted from the imagery were cross- checked in the field.
