The Oahu DEM covers the island of Oahu, Hawaii and incorporates all Oahu communities including the City of Honolulu, which is the largest settlement on the island of Oahu and in the State of Hawaii. 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 2011 to support NOAA's Tsunami Program.
