Central California, CA 1 arc-second MHW DEM

The Central California DEM covers the coastal region north of Santa Cruz to Gualala Point and extends inland to the confluence of the Sacramento and San Joaquin Rivers and seaward past the Farallon Islands and the continental shelf. The DEM has a 1 arc-second (~30 meter) cell size, and is referenced to a vertical datum of mean high water. A smaller, 1/3 arc-second (~10 meter) DEM of San Francisco Bay was also developed. The DEMs were built in July 2010 to support NOAA's Tsunami Program.
