The Desert Research Institute (DRI) is developing strategies that integrate various data types to characterize groundwater resources for the identification of candidate well locations in central Ghana, West Africa. Study areas were selected over which remote sensing data of various scales were assembled along with all available hydrogeologic information. Water samples for chemical analysis were collected and numerous field observations were recorded during the survey of 200 wet and dry boreholes using Global Positioning System (GPS) receivers. All data collected were processed and integrated into a Geographic Information System (GIS). Relationships between features identified in remote sensing data, borehole records and other hydrogeologic characteristics are being examined to maximize water development efficiencies. The GIS modeling results are being tested with an ongoing drilling project. Preliminary results indicate a high correlation between drilling success and proximity to Landsat- derived lineaments
