San Francisco Bay, CA 1/3 arc-second MHW DEM

The San Francisco Bay DEM covers the region inland from the confluence of the Sacramento and San Joaquin Rivers offshore west to the Farallon Islands, extending north to the outlet of the Russian River, and south to San Gregorio Beach. 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, 1 arc-second (~30 meter) DEM of offshore Central California was also developed. The DEMs were built in July 2010 to support NOAA's Tsunami Program.
