        abstract:  NOAA's National Centers for Environmental Information (NCEI) is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions. These integrated bathymetric-topographic DEMs are used to support individual coastal States as part of the National Tsunami Hazard Mitigation Program's (NTHMP) efforts to improve community preparedness and hazard mitigation. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources including: NOAA; the U.S. Geological Survey (USGS); and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to the vertical datum of NAVD 88 and horizontal datum of World Geodetic System 1984 geographic (WGS 84). Grid spacing for the DEM is 1/3 arc-second (~10 meters).
        purpose:  Developed for the National Tsunami Hazard Mitigation Program in support of NOAA's tsunami forecasting and warning efforts.

DEMs are referenced to various vertical and horizontal datums depending on the specific modeling requirements of each State. For specific datum information on each DEM, refer to the appropriate DEM documentation. Cell sizes also vary depending on the specification required by modelers in each State, but typically range from 8/15 arc-second (~16 meters) to 8 arc-seconds (~240 meters).

        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.

        abstract:  A map service showing the location and coverage of land and seafloor digital elevation models (DEMs) available from NOAA's National Centers for Environmental Information (NCEI). 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. Layers available in the map service: Layers 1-4: DEMs by Category (includes various DEMs, both hosted at NCEI, and elsewhere on the web); Layers 6-11: NCEI DEM Projects (DEMs hosted at NCEI, color-coded by project); Layer 12: All NCEI Bathymetry DEMs (All bathymetry or bathy-topo DEMs hosted at NCEI).

            evaluationMethodDescription:  The horizontal accuracy of bathymetric and topographic features in the DEM is dependent upon DEM cell size and the accuracy of the input datasets used to determine corresponding cell values. Topography: 10 meters. Positional accuracy of input topographic datasets limits accuracy of corresponding cell values in DEM. NED topography: 10 meters, Lidar: less than 1 meter. DEM cell-value relative-contribution factors: Lidar: 1000 to 10, Topographic DEM: 10, NED: 1. Bathymetry: less than 1 meter to a few kilometers. Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in DEM. USACE: ~ 5 meters, Multibeam data: ranging from less than 1 meter to 10 meters .

            nameOfMeasure:  Vertical Positional Accuracy Report
            evaluationMethodDescription:  The vertical accuracy of bathymetric and topographic features in the DEM is dependent upon the accuracy of the input datasets used to determine corresponding cell values. Topography: 9 cm to 1 meter. Vertical accuracy of input topographic datasets limits accuracy of corresponding cells in DEM. DEM cell-value relative-contribution factors: Lidar: 1000 to 10, Topographic DEM: 10, NED: 1. Bathymetry: less than 1 meter to 5% of water depth. Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cells in DEM. NOS hydrographic surveys: about 1% of water depth. DEM cell-value relative-contribution factors: USACE and NOS hydrographic surveys: 100, Multibeam: 1, Bathymetric lidar: 10, Bathymetric pre-surface: 1. Gridding interpolation to determine cell values between sparse soundings in deep water degrades the vertical accuracy of corresponding elevations.

        report:  (DQ_ConceptualConsistency)
            measureDescription:  Datasets were 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 was selected for use in that region. Elevations in the older and/or lower-resolution datasets were superceded prior to building the DEM.

                description:  All datasets obtained by NCEI were converted to common horizontal and vertical datums of WGS 84 geographic and NAVD 88, respectively, using VDatum. They were also converted to common file format for visualization and inspection.

                description:  xyz files of the bathymetric data were surfaced using GMT's 'surface' tool onto a 1/3 arc-second grid that interpolated to fill empty cells. Points extracted every 5 meters along the coastline were also included to ensure that the bathymetric grid reached zero at the coast. The resulting Arc ASCII grid was imported into ArcGIS and clipped to the coastline to remove values over land.
