Cordova, AK 1/3 arc-second MHW DEM

The Cordova, Alaska DEM covers eastern portions of Prince William Sound, including the community of Cordova. The DEM has a 1/3 arc-second (~10 meter) cell size, and is referenced to a vertical datum of mean high water. A larger, 3 arc-second (~90 meter) DEM was also developed. The DEMs were built in February 2010 to support NOAA's Tsunami Program.
