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).

report: (DQ_AbsoluteExternalPositionalAccuracy)
nameOfMeasure: Horizontal Positional Accuracy Report
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: 1 to 2 meters. Positional accuracy of input topographic datasets limits accuracy of corresponding cell values in DEM. SRTM topography: 20 meters. Bathymetry: less than 1 meter to a few kilometers. Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in DEM. Multibeam and single survey data: ranging from less than 1 meter to 10 meters.
result: (missing)
report: (DQ_AbsoluteExternalPositionalAccuracy)
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: 0.1 to +/- 10 meters. Vertical accuracy of input topographic datasets limits accuracy of corresponding cells in DEM. SRTM topography: +/- 10 meters. Bathymetry: less than 1 meter to 5% of water depth. Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cells in DEM. Multibeam and singlebeam surveys: about 1% of water depth. Gridding interpolation to determine cell values between sparse soundings in deep water degrades the vertical accuracy of corresponding elevations.
result: (missing)
report: (DQ_CompletenessCommission)
evaluationMethodDescription: NCEI made every effort to obtain all available digital topographic and bathymetric datasets in the region for use in building the DEM.
result: (unknown)
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 deleted prior to building the DEM.
