Generated with Modern Processing Techniques using Geophysical Methods
High Definition elevation, roads and hydrography are constructed from high-resolution stereo satellite photos using robust geophysical processing methods. PhotoSat has recently made a significant technical breakthrough in the processing of detailed elevation maps from high-resolution stereo satellite photos. Geophysical processing methods and software are applied to map elevations from stereo satellite photos.

PhotoSat is producing elevation data with much better elevation accuracy and horizontal resolution than conventional stereo photo elevation mapping processes.
