Northern Gulf Coast, AL/FL/LA/MS 1 arc-second MHW DEM

The Northern Gulf Coast DEM integrates bathymetry and topography along the northern coast of the Gulf of Mexico. It extends from Louisiana's Mississippi River Delta to Cape San Blas in Florida. 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 December 2010 to support NOAA's VDatum Program.
