        abstract:  NOAA's National Geophysical Data Center (NGDC) created a bathymetric digital elevation model (DEM) for the Mariana Trench and adjacent seafloor in the Western Pacific Ocean. Bathymetric data used in DEM compilation were obtained from various sources, including internation, federal and academic partners. The DEM is referenced to the horizontal datum of World Geodetic System 1984 (WGS 84) and the vertical datum of sea level. Grid spacings for the Mariana Trench DEM is 6 arc-seconds (~180 meters). Please note that while positive elevations (elevations greater than 0 meters) are present in the DEM over 'dry' land (i.e. islands such as Guam and the Northern Mariana Islands), they should be ignored as the focus of DEM development was solely in the bathymetric realm.
        purpose:  Developed for the Mississippi State University Geosystems Research Institute and NOAA National Marine Fisheries Service to support scientific visualization efforts.

        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).

            nameOfMeasure:  Horizontal Positional Accuracy Report
            evaluationMethodDescription:  No quantitative horizontal accuracy assessment was performed. The horizontal accuracy of bathymetric features in the DEM is dependent upon the accuracy of the input datasets used to determine corresponding cell values, the process of interpolation/extrapolation, and the resolution of the final output grid.

        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Vertical Positional Accuracy Report
            evaluationMethodDescription:  No quantitative horizontal accuracy assessment was performed. The vertical accuracy of the bathymetric in the DEM is dependent upon the accuracy of the input datasets used to determine corresponding cell values, the process of interpolation/extrapolation, and the resolution of the final output grid. Because of the coarse resolution of the DEM, depths are presented as integer values, as it is effectively impossible to report the values using higher precision.
            result: (missing)
        report:  (DQ_CompletenessCommission)
            evaluationMethodDescription:  NGDC made every effort to obtain best available digital 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 edited prior to building the DEM.
            result: (unknown)
        lineage:  (LI_Lineage)
            processStep:  (LE_ProcessStep)
                description:  All datasets obtained by NGDC were converted to a common ASCII XYZ file format. All data obtained were natively referenced to WGS84. No vertical datum transformations were performed, as any vertical datum offsets between datasets are assumed to be less than vertical accuracy associated with 6 arc-second grid, and are thus effectively equivalent.
