NOAA's National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions in the Gulf of Mexico. These integrated bathymetric-topographic DEMs were developed for NOAA Coast Survey Development Laboratory (CSDL) through the American Recovery and Reinvestment Act (ARRA) of 2009 to evaluate the utility of the Vertical Datum Transformation tool (VDatum), developed jointly by NOAA's Office of Coast Survey (OCS), National Geodetic Survey (NGS), and Center for Operational Oceanographic Products and Services (CO-OPS). Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including NGDC, the U.S. Coastal Services Center (CSC), the U.S. Office of Coast Survey (OCS), the U.S. Army Corps of Engineers (USACE), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to the vertical tidal datum of North American Vertical Datum of 1988 (NAVD 88) or Mean High Water (MHW) and horizontal datum of North American Datum of 1983 (NAD 83). Cell size ranges from 1/3 arc-second (~10 meters) to 1 arc-second (~30 meters). Developed for the Office of Coast Survey (OCS), NOAA Coast Survey Development Laboratory (CSDL) in support of NOAA's Vertical Datum Transformation tool (VDatum). underDevelopment DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce DEM Information dem.info@noaa.gov pointOfContact asNeeded Earth Science > Oceans > Bathymetry/Seafloor Topography > Seafloor Topography Earth Science > Oceans > Bathymetry/Seafloor Topography > Bathymetry Earth Science > Oceans > Bathymetry/Seafloor Topography > Water Depth Earth Science > Land Surface > Topography > Terrain Elevation Earth Science > Land Surface > Topography > Topographical Relief Earth Science > Oceans > Coastal Processes > Coastal Elevation theme NASA/GCMD Earth Science Keywords DEM > Digital Elevation Model theme NASA/GCMD Platform Keywords DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce WDC/MGG, BOULDER > World Data Center for Marine Geology and Geophysics, Boulder theme NASA/GCMD Data Center Keywords H: 1 meter - < 30 meters V: < 1 meter theme NASA/GCMD Data Resolution Keywords Coastal Relief Gridded elevations Integrated bathymetry and topography theme Uncontrolled Continent > North America > United States of America Ocean > Atlantic Ocean > North Atlantic Ocean Ocean > Atlantic Ocean > North Atlantic Ocean > Gulf of Mexico Vertical Location > Land Surface Vertical Location > Sea Floor place NASA/GCMD Location Keywords Not to be used for navigation.

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. They can be used for modeling of coastal processes (tsunami inundation, storm surge, sea-level rise, contaminant dispersal, etc.), ecosystems management and habitat research, coastal and marine spatial planning, and hazard mitigation and community preparedness. DEMs included in this visualization: High-resolution DEMs of select U.S. coastal communities and surrounding areas. Most are at a resolution of 1/3 to 1 arc-second (approx 10-30 m); U.S. Coastal Relief Model: A 3 arc-second (approx 90 m) comprehensive view of the conterminous U.S. coastal zone, Puerto Rico, and Hawaii; Southern Alaska Coastal Relief Model: A 24 arc-second (approx. 500 m) model of Southern Alaska, spanning the Bering Sea, Aleutian Islands, and Gulf of Alaska. This map service can be used as a basemap. It has a transparent background, so it can also be shown as a layer on top of a different basemap.

Vertical Positional Accuracy Report The vertical accuracy of bathymetric and topographic features in the DEM is dependent upon DEM cell size and the accuracy of input datasets used to determine corresponding cell values. Gridding interpolation to determine values between sparse NOS hydrographic soundings in deep water degrades the vertical accuracy of deep-water elevations. NGDC makes every effort to obtain all available digital topographic and bathymetric datasets in each region for use in building the DEMs. Datasets are visually compared internally and externally (with other overlapping datasets and satellite images and maps) in ESRI ArcGIS for identification of anomalous elevations or data inconsistencies. Where elevation inconsistencies occurred, the most recent and/or highest resolution data set are selected for use in that region. Elevations in the older and/or lower-resolution datasets are deleted prior to building the DEMs. All datasets obtained by NGDC are converted to common horizontal and vertical datums of NAD 83 geographic and NAVD 88, respectively, using FME and VDatum transformation tool. They are also converted to common file format, ESRI point shapefiles, for visualization and inspection. 2009-12-01T00:00:00 Matthew R. Love DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Matthew.Love@noaa.gov pointOfContact Datasets are visually inspected with ArcGIS for identification and editing of data anomalies. Datasets are then compared with overlapping datasets to ensure data consistency. 2009-12-01T00:00:00 xyz files of the bathymetric data are surfaced using GMT's 'surface' tool onto a 1 arc-second grid that is interpolated to fill empty cells. Points extracted every 10 meters along the coastline are also included to ensure that the bathymetric grid reaches zero at the coast. The resulting Arc ASCII grid is imported into ArcGIS and clipped to the coastline to remove values over land. 2009-12-01T00:00:00 xyz files for each input dataset are gridded using MB-System's 'mbgrid' tool, which utilizes a high-tension spline interpolation method to fill grid cells with no input elevation values. Preferential weighting is given to more recent, higher-accuracy datasets. Gridding is typically performed in quadrants, each with a 5% data buffer. The grids are imported in ArcGIS and seamlessly merged to create an NAVD 88 DEM. 2009-12-01T00:00:00 The DEMs are quantitatively evaluated by comparing with source datasets and with elevation values extracted from NGS geodetic monuments. They are visually evaluated by converting to UTM-zone coordinates (units of meters horizontally and vertically) and then creating a slope grid to identify gridding artifacts in the DEMs. 2009-12-01T00:00:00 NOAA's VDatum transformation tool is used to derive an NAVD 88-to-MHW conversion grid. This grid is then added to the NAVD 88 DEM to create a MHW DEM. 2009-12-01T00:00:00 annually This metadata was automatically generated from the Content Standard for Digital Geospatial Metadata: Extensions for Remote Sensing Metadata standard (version FGDC-STD-012-2002) using the 2012-08-07 version of the FGDC RSE to ISO 19115-2 transform for DEMs. Translated from FGDC 2012-08-08T17:16:57.569-06:00 Kelly Carignan DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce kelly.carignan@noaa.gov pointOfContact
