Groundwater Potential Mapping
Flow chart showing the methodology
3D Visualization of surface cover – FCC over DEM This visual, shows the aerial view of the area. Perspective view of the terrain was generated using Digital elevation model was superimposed with the IRS false color image and the road network and drainage layers, generated using GIS.

Map showing the ground water sites for exploitation Various terrain layers (geology, geomorphology, structure, drainage, road network and settlements) were integrated using GIS. The probability ground water potential is very high at the intersection of fracture patterns in this hard rock area.
