The Cordova, Alaska DEM covers eastern portions of Prince William Sound, including the community of Cordova. Larger DEMs of Prince William Sound were also developed. 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.
