The study is aimed at the development of processing methods of remotely sensed data from satellite for extraction of the groundwater potential areas. Analyses of the existing operational wells for groundwater supply indicate that 81 % of them are related with lineaments and 51 % of them are located at the intersections of lineaments. Thus the features of lineaments are considered to be one of the most important parameters to extract a high potential area of groundwater. Taking into account features of lineaments and also information obtained from geographic information system, high potential points for groundwater were extracted from landsat TM data based on the theory developed in the research, then verifications were made through actual boring. The result of verification indicates that 9 out of 18 points yield more 200 cubic meter/day which is the amount required from economical point of view for an operational use. Since actual boring was made not on the recommended points for 4 points which did not yield enough output due to difficulty of approach to the exact points and approval for boring could not be obtained the result might have been improved if the exact points were bored and if boring had been made deeper since the maximum depth of boring was limited to 62 meters.
