Key West, FL 1/3 arc-second MHW DEM

The Key West DEM integrates bathymetry and topography in the area surrounding the town of Key West, Florida. It emcompasses many of the lower Keys including Bahai Honda, Big Pine, Cudjow, Sugerloaf, and Boca Chica east of Key West, and Boca Grande and Marquesas Keys west of Key West. 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 September 2011 to support NOAA's Tsunami Program.
