NOAA NCEI Coastal Digital Elevation Model - 1/9 Arc-Second Resolution Bathymetric-Topographic Tiles

Metadata Updated: February 27, 2019

NOAA's National Centers for Environmental Information (NCEI) is developing a suite of digital elevation models (DEMs) for the U.S. coast to support a variety of NOAA missions, including improved inundation modeling and mapping, habitat characterization, and visualization of Earth's surface.

      The DEMs are being developed according to a 0.25 degree tiling scheme. The spatial resolution
      of the tiles "telescopes" from the coastal zone to the deep ocean floor at 1/9, 1/3, 1 and 3 arc-second grid resolution.
      Only the 1/9 arc-second DEM tiles integrate both bathymetric and topographic data; all other resolutions map bathymetry only.
      The tiling of the DEMs facilitates targeted, rapid updates as new coastal and marine elevation data are acquired and become available.
      Bathymetric and topographic data utilized for DEM creation originate from a variety of sources, including (but not limited to) the NOAA Office
      of Coast Survey, NOAA National Geodetic Survey, NOAA Office for Coastal Management, U.S. Geological Survey, and the U.S. Army Corps of Engineers.

      The DEMs are referenced vertically to the North American Vertical Datum of 1988. The vertical units of the DEMs are meters. The DEMs are referenced horizontally to the North
      American Datum of 1983. The horizontal units of the data are decimal degrees.
