The Ocean City DEM integrates bathymetry and topography in the area surrounding the town of Ocean City, Maryland. It spans the dynamic barrier islands of Fenwick and Assateague, located off the Delaware, Maryland and Virginia coasts. 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 2009 to support NOAA's Tsunami Program.
