Regional Coastal Digital Elevation Models from NOAA/NGDC
NOAA’s National Geophysical Data Center (NGDC) builds and distributes high-resolution, coastal digital elevation models (DEMs) that integrate ocean bathymetry and land topography to support NOAA’s mission to understand and predict changes in Earth’s environment, and conserve and manage coastal and marine resources to meet our Nation’s economic, social, and environmental needs. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including NGDC, the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to a variety of vertical tidal datums, generally Mean High Water, and horizontal datum of World Geodetic System 1984 (WGS84). Cell size is based on user requirements and generally range from 1 arc-second (~30 meters) to 24 arc-seconds.
