Stereoscopy is the science of using overlapping Imagery acquired from different locations to produce a 3D model that emulates true binocular vision. The main applications of photogrammetric stereo techniques are the identification, measurement, and manual digitization of 3D features from properly triangulated stereo model.
Stereo mapping consists of preparing vector or topographic data from stereo aerial or satellite Images based on specification and demand of the public and private administrative tasks. Specification for mapping of topographic and thematic features depends on the client’s requirements that may vary with individual countries and projects.
Grameentech uses world class photogrammetric workstations, SUMMIT EVOLUTION, of DAT/EM systems international for 3D feature collections with ArcEnterprise and AutoCAD plugin.
