Satellite survey WV2 case history for oil and gas client in Ghadames, Libya From August to November of 2010 PhotoSat produced a 3,962 km2 1m survey grid from 50cm WorldView-2 stereo satellite photos for a project in Ghadames, Libya. The client hoped that by utilizing stereo satellite elevations during and after a highly accurate seismic survey they could improve the efficiency of their project. The stereo satellite elevation surveying was initially referenced to 19 ground survey targets and 85,000 seismic source points with precise GPS elevations, as shown in Figure 1. The resulting horizontal match between the targets and the 50cm resolution stereo WorldView-2 satellite photos was approximately 25cm. Following the completion of the DEM processing an additional 86,000 seismic source point
