Count Component Title Abstract
1 Continuously Updated Digital Elevation Model (CUDEM) - 1/9 Arc-Second Resolution Bathymetric-Topographic Tiles 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, 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.

        1 2015-04-22T00:00:00 NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
        1 2018-02-01T00:00:00 Common horizontal reference frames and vertical datums are established among disparate data and data are converted to a common data format, ASCII xyz, prior to gridding/interpolating. A variety of software can be used for projection/datum transformations and format conversions, including (but not limited to) Geospatial Data Abstraction Library (GDAL) software utilities, VDatum, ArcGIS, LAStools, etc. Once consistency among the input source data is established, the DEM surface is created through gridding and interpolation. Elevations in grid-cells constrained by source measurements are assigned a value according to a weighted average of all samples located within the particular cell, while elevations in unconstrained grid-cells are estimated through interpolation. Please see the DEM technical reports for a more detailed explanation of specific processing steps.
