Galveston, TX 1/3 arc-second MHW DEM

The Galveston DEM integrates bathymetry and topography in the area surrounding the city of Galveston, Texas. It covers the Galveston Bay estuarine system and its tributaries, and includes the communities of Texas City, Dickinson, La Porte, Baytown and Gilchrist. 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 May 2007 to support NOAA's Tsunami Program.
