Abstract
Categorizing of Land Use/Land Cover (LU/LC) is a dynamic investigation field in ecological remote sensing applications on the earth’s surface. The latest multispectral sensors having good resolution with distinctive bands enabled a chance to plot the three-dimensional transmission of elaborated LU/LC categories on a huge disjointed region. The current research encompasses generation of thematic maps i.e. LU/LC map, Geology map and watershed map and finally preparing integrated map by merging LU/LC and geology layers to identify the area of LU/LC classes spread over in diverse lithological units of the area under study. IRS P6 (LISS-III) image data & Advanced Wide Field Sensor (AWiFS) image data were used to derive two seasons (Kharif & Rabi) information of LU/LC by using well versed supervised classification procedure. Geology map delineated from Geological Survey of India map and updated lithological boundaries by superimposing on IRS P6 LISS-III multi-spectral satellite data was used. Apart from these, drainage map and base map were prepared by using topographical maps of Survey of India (SOI) and updated these layers by superimposing on IRS P6 LISS-III multi-spectral satellite image. The study clinches that among all LU/LC classes of the study area; Fallow lands took first place by occupying an area of 443.42 Sq.Km. (35.27%), followed by double crop land occupying an area of 363.00 Sq.Km. (28.98%). The study area was categorized into six sub-watersheds and seventeen check dams, three percolation tanks and one nallah bund were suggested to enhance groundwater levels. Based on the integration of LU/LC and geology layers, it is observed that 99.72% of the LU/LC classes were spatially distributed in igneous rock body of Graniegneissic terrain and remaining part LU/LC classes spatially distributed in ABS & MB, AV and BIF.
