New Orleans, MS/LA 1/3 arc-second MHW DEM

The New Orleans DEM integrates bathymetry and topography in the area surrounding New Orleans, Louisiana. It covers Lake Pontchatrain and Lake Borgne, a portion of southwestern Mississippi, and extends out along the Mississippi River Delta. 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 April 2010 to support NOAA's VDatum Program.
