Taholah, WA 1/3 arc-second MHW DEM

The Taholah DEM integrates bathyemtry and topography along the southern to central coastline of Washington, from Grays Harbor to Kalaloch. The northern and southern part of the DEM overlaps NGDC's Astoria, Oregon and La Push, Washington DEMs by about 11 km. The Taholah 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 July 2009 to support NOAA's Tsunami Program.
