The Kachemak Bay DEM covers the entire Kachemak Bay of Alaska, and includes the towns of Homer and Seldovia. Kachemak Bay is located on the Kenai Peninsula, about 100 miles south of Anchorage. 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 December 2010 to support NOAA's Tsunami Program.
