Pago Pago, AS 3 arc-second MHW DEM

The Pago Pago DEM integrates bathymetry and topography around American Samoa. It spans the American Samoa islands of Tutuila, Ofu, Olosega and Tau, including the capitol city of Pago Pago on Tutuila, and surrounding deep ocean floor. The DEM has a 3 arc-second (~90 meter) cell size, and is referenced to a vertical datum of mean high water. A smaller, 1/3 arc-second (~10 meter) DEM was also developed. They were built in September 2009 to support NOAA's Tsunami Program.
