The Virginia Beach DEM integrates bathymetry and topography in the area surrounding the town of Virginia Beach, Virginia. It covers coastal areas south to North Carolina, the city of Norfolk, the mouth of Chesapeake Bay and the southern tip of the Delmarva peninsula. 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 January 2007 to support NOAA's Tsunami Program.
