The Guayama DEM integrates bathymetry and topography in the area surrounding the town of Guayama on the island of Puerto Rico. The DEM has a 1/3 arc-second (~10 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 developed a separate 1 arc-second DEM covering the entire island of Puerto Rico within the coordinate boundaries 65° to 68° W and 17° to 19° N.
