ABSTRACT: Remote Sensing (RS) and geographic information system (GIS) are now very
essential tools for efficient planning and management and handling a range of
data simultaneously in a time- and cost-efficient manner for targeting of
groundwater, which assists in measuring, monitoring, and conserving
groundwater resources. Survey of India toposheets, LISS-III and CARTOSAT
DEM satellite imageries are used to prepare various thematic layers viz., geology,
slope, lineament, drainage, and geomorphology, and were transformed to
raster data using feature to raster conversion tool in ArcGIS spatial analysis,
then we reclassify each raster map using reclassify tools. By using weight
overlay analysis, each weighted thematic layer is statistically computed to get
the ground water potential zones. Then, five different groundwater potential
zones were identified, namely “very good”, “good”, “moderate”, “poor”, and
“very poor”. The villages under poor groundwater potential zone and the villages
under very good groundwater potential zone are finding out. The above
study has clearly demonstrated the capabilities of Remote Sensing and GIS in
demarcation of the different groundwater potential zones in hard rock terrain.
