Geoimage is introducing the use of Tri-Stereo; an acquisition method designed to produce a more accurate elevation model than seen with stereo image pairs. Tri-Stereo is composed of three near-simultaneously acquired images that are merged to present a precise and detailed digital elevation model (DEM). The target area is scanned from three different directions (backwards, forwards, and near-nadir), allowing better retrieval of elevation values over terrains without the risk of overlooking hidden items. The stability of Tri-Stereo modelling provides added accuracy and detail to the produced DEM by reducing occlusions caused by limitations such as high roughness, steep slopes and shadows.
