Though the production of thematic data does not always require having a 3D view, the development of StereoSatTM has allowed us to acquire unique expertise in producing thematic data via the photo-interpretation of real or synthetic stereo satellite images.
During the data production process, one of our thematic specialists (geomorphologist, forest expert or geologist) extracts the information directly from digital photogrammetric workstations. That makes it possible to have a 3D view and has significant advantages, such as consideration of the topographical context, which helps more accurately delineate the features to be mapped, along with faster execution.
