Prince William Sound, AK 8/3 arc-second MHHW DEM

The Prince William Sound 8/3 arc-second DEM covers all of Prince William Sound and the adjacent regions of the Gulf of Alaska, including the communities of Whittier, Cordova, and Valdez. Smaller DEMs of the communities of Whittier and Cordova were also developed, as well as a coarser, 3 arc-second DEM of Prince William Sound. The DEMs were built in April 2009 to support the State of Alaska's efforts to improve the resiliency of its coastal communities to tsunamis.
