Adak, AK 1 arc-second MHW DEM

The Adak DEM integrates bathymetry and topography in the area surrounding Adak Island, which is located in the Andreanof Islands on the Aleutian Islands Chain of Alaska. The DEM encompasses the eastern half of Kanaga Island, Adak Island, Kagalaska Island, Little Tanaga Island, Umak Island, Great Sitkin Island, and Igitkin Island. 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 April 2009 to support NOAA's Tsunami Program.
