Geologic lineament mapping is considered as a very important issue for the problem solving in Ground water, especially in selecting the site for construction (dams, bridges and road.), minerals exploration and hydrological research. The regional study and automated extraction of linear features such as faults, joints, folds, dikes, crustal fracturing, and lithological contacts from remotely sensed imagery has been the subject of extensive research over several decade. The structural information is represented on the map using different symbols. The symbols are shown as fixed part of the legend given at. The main structural features that control the occurrence and movement of ground water are faults, fractures, joints, dykes, etc .Availability of ground water along fractures and faults is better as compared to its immediate surroundings. The dykes work as a barrier for the flow of ground water. Thus in up slope front of a dyke ground water availability is better as compared to the down slope side. Soil covers the major part of the area under study that makes the job of identification of structural elements a difficult problem However, the drainage map prepared from the topographical map and the satellite data reflect the linears to a great extent....
