These integrated bathymetric-topographic DEMs were developed for NOAA Coastal 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), Mean High Water (MHW) or Mean Lower Low Water (MLLW) 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). The NOAA VDatum DEM Project was funded by the American Recovery and Reinvestment Act (ARRA) of 2009 (http://www.recovery.gov/). purpose: Developed for the Office of Coast Survey (OCS), NOAA Coastal Survey Development Laboratory (CSDL) in support of NOAA's Vertical Datum Transformation tool (VDatum). status: (MD_ProgressCode) completed status: (MD_ProgressCode) historicalArchive pointOfContact: (CI_ResponsibleParty) organisationName: NOAA National Centers for Environmental Information contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: ncei.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://www.ncei.noaa.gov/contact name: NCEI Contact Information description: Information for contacts at NCEI. function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) pointOfContact pointOfContact: (CI_ResponsibleParty) organisationName: NOAA National Centers for Environmental Information positionName: DEM Information contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: dem.info@noaa.gov role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded graphicOverview: (MD_BrowseGraphic) fileName: https://maps.ngdc.noaa.gov/thumbnails/DEM/720.png fileDescription: Thumbnail of DEM fileType: PNG descriptiveKeywords: (MD_Keywords) keyword: Earth Science > Oceans > Bathymetry/Seafloor Topography > Seafloor Topography keyword: Earth Science > Oceans > Bathymetry/Seafloor Topography > Bathymetry keyword: Earth Science > Oceans > Bathymetry/Seafloor Topography > Water Depth keyword: Earth Science > Land Surface > Topography > Terrain Elevation keyword: Earth Science > Land Surface > Topography > Terrain Elevation > Topographical Relief Maps keyword: Earth Science > Oceans > Coastal Processes > Coastal Elevation type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Science Keywords date: (CI_Date) date: 2020-01-09 dateType: (CI_DateTypeCode) publication edition: 9.1 citedResponsibleParty: (CI_ResponsibleParty) organisationName: NASA Goddard Space Flight Center, Earth Science Data and Information System contactInfo: (CI_Contact) onlineResource: (CI_OnlineResource) linkage: https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords name: Global Change Master Directory (GCMD) Keywords description: The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

Either individual DEMs or small subsets can be accessed through this service. function: (CI_OnLineFunctionCode) search role: (CI_RoleCode) publisher abstract: The DEM Global Mosaic is an image service providing a global, seamless bathymetry/topography mosaic that includes NCEI's ETOPO 2022, NCEI's Continuously Updated DEM (CUDEM), and other NCEI-stewarded DEMs, along with regional grids such as IBCAO, IBCSO and the Hawaiian Island Multibeam Synthesis (University of Hawaii). This service provides elevation/depth values in meters; for a visualization of the data, please see the related DEM Global Mosaic (Color Shaded Relief) service. There are 5 related image services providing access to Digital Elevation Models: DEM Mosaic (Individual DEMs), DEM Global Mosaic (Elevation Values), DEM Global Mosaic (Color Shaded Relief), CUDEM Mosaic (Elevation Values), and CUDEM Mosaic (Color Shaded Relief). NCEI 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. This service is a general-purpose global, seamless bathymetry/topography mosaic. It combines DEMs from a variety of near sea-level vertical datums, such as mean high water (MHW), mean sea level (MSL), and North American Vertical Datum of 1988 (NAVD88). No conversion/harmonization of vertical datums was performed. Because the mosaic contains 'overviews' for performance, individual DEMs cannot be separated from the others. Individual DEMs, or smaller subsets, are available in the companion DEM Mosaic (Individual DEMs) image service. By default, the DEMs are drawn in order of cell size, with higher-resolution grids displayed on top of lower-resolution grids. If overlapping DEMs have the same resolution, the newer one is shown. Please see NCEI's corresponding DEM Footprints feature service for polygon footprints and more information about the individual DEMs used to create this composite view. pointOfContact: (CI_ResponsibleParty) individualName: NCEI GIS Team organisationName: NOAA National Centers for Environmental Information contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: ncei.gis@noaa.gov role: (CI_RoleCode) pointOfContact descriptiveKeywords: (MD_Keywords) keyword: DATA ANALYSIS AND VISUALIZATION > GEOGRAPHIC INFORMATION SYSTEMS > WEB-BASED GEOGRAPHIC INFORMATION SYSTEMS keyword: DATA MANAGEMENT/DATA HANDLING > DATA SEARCH AND RETRIEVAL keyword: DATA ANALYSIS AND VISUALIZATION > VISUALIZATION/IMAGE PROCESSING type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Service Keywords date: (CI_Date) date: 2020-01-09 dateType: (CI_DateTypeCode) publication edition: 9.1 citedResponsibleParty: (CI_ResponsibleParty) organisationName: NASA Goddard Space Flight Center, Earth Science Data and Information System contactInfo: (CI_Contact) onlineResource: (CI_OnlineResource) linkage: https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords name: Global Change Master Directory (GCMD) Keywords description: The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

NCEI 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. This service provides data from many individual DEMs combined together as a mosaic. By default, the rasters are drawn in order of cell size, with higher-resolution grids displayed on top of lower-resolution grids. If overlapping DEMs have the same resolution, the newer one is shown. Alternatively, a single DEM or group of DEMs can be isolated using a filter/definition query or using the "Lock Raster" mosaic method in ArcMap. This is one of three services displaying collections of DEMs that are referenced to common vertical datums: North American Vertical Datum of 1988 (NAVD88): http://noaa.maps.arcgis.com/home/item.html?id=e9ba2e7afb7d46cd878b34aa3bfce042, Mean High Water (MHW): http://noaa.maps.arcgis.com/home/item.html?id=3bc7611c1d904a5eaf90ecbec88fa799, and Mean Higher High Water: http://noaa.maps.arcgis.com/home/item.html?id=9471f8d4f43e48109de6275522856696. In addition, the DEM Global Mosaic is a general-purpose global, seamless bathymetry/topography mosaic containing all the DEMs together. Two services are available: http://noaa.maps.arcgis.com/home/item.html?id=c876e3c96a8642ab8557646a3b4fa0ff Elevation Values: http://noaa.maps.arcgis.com/home/item.html?id=c876e3c96a8642ab8557646a3b4fa0ff and Color Shaded Relief: http://noaa.maps.arcgis.com/home/item.html?id=feb3c625dc094112bb5281c17679c769.

Points extracted every 10 meters along the coastline were also included to ensure that the bathymetric grid reached zero at the coast. The resulting Arc ASCII grid was clipped to the coastline to remove values over land. dateTime: DateTime: 2010-11-14T00:00:00 processStep: (LE_ProcessStep) description: xyz files for each input dataset were 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 was given to more recent, higher-accuracy datasets. Gridding was performed with a 5% data buffer. dateTime: DateTime: 2010-11-23T00:00:00 processStep: (LE_ProcessStep) description: The NAVD 88 DEM was quantitatively evaluated by comparing with source datasets and with elevation values extracted from NGS geodetic monuments.
