Pago Pago, AS 1/3 arc-second MHW DEM

The Pago Pago DEM integrates bathymetry and topography around Tutuila Island, the westernmost island of American Samoa. It covers the entire island, including the capitol city of Pago Pago, and extends onto the slopes of the volcanic pedestal. 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. They were built in September 2009 to support NOAA's Tsunami Program.
