Description

Digital elevation models (DEMs) of U.S. coasts 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. These models, built and distributed by NOAA?s National Geophysical Data Center (NGDC), utilize bathymetric, topographic, and shoreline data 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 (MHW) or North American Vertical Datum of 1988 (NAVD 88), and a horizontal datum of North American Datum of 1983 (NAD 83) or World Geodetic System 1984 (WGS84). DEM cell sizes range from high-resolution models (1/9 to 1/3 arc-second; ~3 to 10 meters) that support coastal inundation studies, to regional models (roughly 3 to 24 arc-seconds) that extend farther offshore, to global models (1 arc-minute; ~2 km).
