The U.S. Virgin Islands DEM integrates bathymetry and topography over the entire region of the U.S. Virgin Islands, including the British Virgin Islands. The DEM has a 1 arc-second (~30 meter) cell size, and is referenced to a vertical datum of mean high water. It was built in October 2010 to support NOAA's Tsunami Program. NGDC has built two separate, higher-resolution DEMs that cover the islands of St. Croix and St. Thomas-St. John.
