Remote Sensing (RS) and Geographic Information System (GIS) are essential tools for mapping & integration of geology, geomorphology, slope, soil, drainage, lineament, landuse/cover and other related features that help in assessing the ground water resources of a region. This paper aims to integrate RS and GIS techniques to delineate groundwater potential zones in the typical hard rock terrain of a region in Karnataka, South India. Efforts have been made to evaluate the groundwater potential zones using the False Colour Composite (FCC) images of IRS-1D (PAN+LISS-III). Slope map was prepared by using Survey of India (SoI) toposheets (year-2001) of 1:50,000 scale. Thematic maps have been prepared by adopting visual interpretation techniques and were integrated by using Arc Info GIS v3.2. The resultant composite coverage was used to classify the area into excellent, good, moderate and poor groundwater potential zones based on certain weightages. The final results highlight the favorable conditions of groundwater potential zones in the hard rock terrain around Kollegal Shear Zone (KSZ) of South India, which is a suitable model for application to similar geological conditions.
