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.
PGC DEM Products – ArcticDEM, REMA, and EarthDEM
PGC's DEM products are collaborative projects to produce 2-meter resolution Digital Elevation Models across the Arctic, Antarctic, and mid-latitudes.
Introduction to Stereoscopic Imagery
Explore the differences between monoscopic and stereoscopic satellite imagery.
PGC uses open-source libraries such as SETSM and ASP to generate stereo-derived elevation models.
Important information about license, acknowledgement and use in academic journals or the web.
