Nantucket, MA 1/3 arc-second MHW DEM

The Nantucket DEM integrates bathymetry and topography in the area surrounding the town of Nantucket, Massachusetts. It spans Nantucket Sound, from Martha's Vineyard to Nantucket Island, then north to Cape Cod, and extending into the Atlantic Ocean. 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 October 2008 to support NOAA's Tsunami Program.
