PhotoSat has completed digital elevation mapping of Concordia's Providencia Ag-Cu deposit in northwestern Argentina using stereo satellite photos from GeoEye-1, the world's highest resolution commercial imaging satellite. The GeoEye-1 satellite is owned by GeoEye of Herndon, Virginia, one of the world's largest commercial high resolution satellite companies. The PhotoSat digital elevation map consists of an elevation point every metre and contours with 1m elevation intervals. Based on comparisons between the stereo satellite elevation mapping and thousands of ground survey points on similar projects, the accuracy of the stereo satellite elevation mapping is expected to be better than 50cm in elevation. The stereo satellite elevation mapping will be used for planning and engineering studies for the Providencia Ag-Cu deposit...
