Strait of Juan de Fuca 1/3 arc-second NAVD 88 Coastal Digital Elevation Model |
NOAA?s National Centers for Environmental Information (NCEI) 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: NOAA; the U.S. Geological
Survey (USGS); and other federal, state, and local government agencies, academic institutions,
and private companies. DEMs are referenced to the vertical datum of NAVD 88 and horizontal
datum of World Geodetic System 1984 geographic (WGS 84). Grid spacing for the DEM
is 1/3 arc-second (~10 meters). |
