摘要：Ground water contributes to about 80% of the drinking water requirements in the rural areas, fifty percent of the urban water requirements and more than fifty percent of the irrigation requirements of the nation.The search for new groundwater resources is essential to sustained economic development in arid environment. The study area is around Bengaluru urban falling between latitude of 12° 58‘ N to 77° 38' E at Survey of India toposheets 57 G & H covering an area of 2,191 sq.km in Karnataka State, India. In the present paper, by methodological approach based on remote sensing &GIS, Topographical maps are to be prepared using the ARCGIS, and LISS IV data. The area is characterized by undulating terrain interspersed by low ranges of rocky hills. The elevation ranges from 883 to 940 m above MSL .Thus the different ground water potential zones are identified in to 4 classes namely ‘good’, ’moderate’ , ‘moderatepoor’ and ‘poor’.
