The Montauk DEM integrates bathymetry and topography in the area surrounding the town of Montauk, New York. It covers the easternmost area of Long Island, including Long Island Sound, the communities of Easthampton and Southampton on Long Island, and the coastal communities of Mystic and Old Saybrook, CT. 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 2007 to support NOAA's Tsunami Program.
