摘要：The Remote Sensing and GIS tools have opened new paths in land and water resource studies, presently. Satelliteimages are increasingly used in ground water exploration because of their utility in identifying various geomorphicfeatures. In the present study, all the prepared thematic data layers such as slope, relief, soil, geology, geomorphology,drainage, land use and 'NDVI' are integrated using the Spatial Analyst Tool in Arc GIS 9.2 implying weighted overlaymethods to delineate the Ground Water Potential Zones in Kangshabati Irrigation Command Area (KICA). In weightedoverlay analysis rank value assigned for each class of all thematic data layers according to their influence on groundwater hydrology and factor weighted values are assigned according to analytical hierarchy process (AHP). Finally, anaccuracy study is being performed in ERDAS Imagine Software by ground truth verification of 30 training sites withGPS readings for major land use/ land cover information which states the overall classification accuracy of the presentstudy is 86.66%.
