[GD10-4] Stereoscopy and orthoimagery

A stereoscopy acquisition mode collects remotely sensed data where each location on the ground (or the imaged objects) is covered multiple times (at least twice), from different perspectives. Stereopairs and stereoscopic coverage enable the extraction of 3D representations of the environment from remotely sensed imagery.
