High Resolution Satellite Imagery DTMs and GeoEye

GeoEye-1 stereo satellite imagery is capable of producing Digital Terrain Models (DTM) with better then 0.5m vertical accuracy. AAMHatch tasked the GeoEye-1 satellite to capture stereo data over a 270sqkm area in Eastern Australia. The application was an engineering study for the energy sector with the client requiring a 0.5m ortho-image with 2m contours.

GeoEye-1's unsurpassed agility and maneuverability assists in rapid stereo capture. This image was cloud-free, and delivered to AAMHatch for processing within 48 hours of capture. Survey accurate ground control points, distributed evenly across the area, were used in the image processing. These points enabled consistent accuracies to be derived throughout the project area.
