Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) - The GDEM was created by processing and stereo-correlating the 1.3 million-scene ASTER archive of optical images, covering Earth's land surface between 83 degrees North and 83 degrees South latitudes. The GDEM is produced with 30-meter (98-feet) postings, and is formatted as 23,000 one-by-one- degree tiles. The GDEM is available for download from NASA's EOS data archive and Japan's Ground Data System.

Avalanche Mapping - This is a project to collect digital avalanche and snowpit data promote avalanche information sharing. It is the only project dedicated to building avalanche path atlases and GIS data for avalanche modeling and forecasting.
