Stereo Elevation Models

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.

Guides

• Introduction to Stereoscopic Imagery

  Explore the differences between monoscopic and stereoscopic satellite imagery.

• Processing Algorithms

  PGC uses open-source libraries such as SETSM and ASP to generate stereo-derived elevation models.

• Usage Guidelines

  Important information about acknowledgement and use in academic journals or the web.

• Requesting Existing DEMs

  Detailed workflow for searching for pre-produced DEMs and requesting them from the PGC.

• Requesting New DEMs

  Detailed workflow for searching for stereo satellite imagery and requesting a custom-created DEM from PGC.
