The Puerto Rico DEM integrates bathymetry and topography over the entire island of Puerto Rico, extending from 65° to 68° W and 17° to 19° N. 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 June 2007 to support NOAA's Tsunami Program. NGDC has built six separate, higher-resolution DEMs that cover the coastal communities of Arecibo, Fajardo, Guayama, Mayaguez, Ponce, and San Juan.
