Stereo-Photogrammetric Digital Elevation Models (DEM)

The PGC distributes high-resolution elevation models from various processing methods, including the Surface Extraction with TIN-based Search-space Minimization (SETSM) and Ames Stereo Pipeline (ASP). The Digital Elevation Models (DEMs) provided are gridded surface elevation data constructed from overlapping pairs high-resolution (~0.5 m) images acquired by the DigitalGlobe, Inc. Worldview-1 and 2 satellites through the NGA EnhancedView license. The DEMs are built using photogrammetric techniques in which common features are identified in each image and are used to model the relative three dimensional position of the terrain.

Nepal Earthquake Elevation Model

These surface models are produced using the Surface Extraction with TIN-based Search-space Minimization (SETSM) algorithm from M.J. Noh and I. Howat at the Ohio State University. The Digital Elevation Models (DEM) provided here are gridded surface elevation data constructed from overlapping pairs of high-resolution (~0.5 m) images acquired by the DigitalGlobe, Inc. WorldView-1 and WorldView-2 satellites licensed through the NGA EnhancedView program. The elevation models can be freely distributed, but please read the FAQ for documentation and proper citation.

Antarctic LiDAR: McMurdo Dry Valleys & Ross Island

A LiDAR campaign was completed in 2001 by the U.S. Geological Society to cover areas of interest in Antarctica's McMurdo Dry Valleys and Ross Island. The data provided below are 32-bit elevation rasters (GeoTIFF) zipped for each area. For more information, visit the U.S. Antarctic Resource Center or read the Site Report.
