San Juan Islands, Washington Coastal Digital Elevation Model
browse graphicNOAA’s National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions. These integrated bathymetric-topographic DEMs are used to support individual coastal States as part of the National Tsunami Hazard Mitigation Program’s (NTHMP) efforts to improve community preparedness and hazard mitigation. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources including: NGDC; the U.S. Geological Survey (USGS); Naval Oceanographic Office (NAVOCEANO); NOAA’s Coastal Service Center; and other federal, state, and local government agencies, academic institutions, and private companies. The DEM is referenced to the vertical tidal datum of Mean High Water (MHW).
