The PGC provides Digital Elevation Models (DEM) derived from DigitalGlobe, Inc. optical imagery to United States federally-funded polar researchers. These guides will introduce stereoscopic imagery, explain eligibility and license restrictions and workflow for requesting existing or newly-created DEMs through the PGC.
