Liu, H., K. Jezek, B. Li, and Z. Zhao. 2001. Radarsat Antarctic Mapping Project digital elevation model version 2. Boulder, CO, USA: National Snow and Ice Data Center. Digital media. Available at http://nsidc.org/data/nsidc-0082.html. 01 November 2006. Background: The high-resolution Radarsat Antarctic Mapping Project (RAMP) Digital Elevation Model (DEM) combines topographic data from a variety of sources to provide consistent coverage of all of Antarctica. Version 2 improves upon the original version by incorporating new topographic data, error corrections, extended coverage, and other modifications. The DEM incorporates topographic data from satellite radar altimetry, airborne radar surveys, the recently-updated Antarctic Digital Database (version 2), and large-scale topographic maps from the U.S. Geological Survey (USGS) and the Australian Antarctic Division. Data were collected between the 1940s and present, with most collected during the 1980s and 1990s. Although the RAMP DEM was created to aid in processing RAMP radar data, it does not utilize any RAMP radar data. The Atlas of the Cryosphere uses the RAMP DEM gridded at 1 km. NOTE: WCS requests include elevations below 100 m (despite the layer name) while WMS requests do not. Liu, H., K. Jezek, B. Li, and Z. Zhao. 2001.
