        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:  This is a tiled map service showing color shaded relief visualizations of high-resolution digital elevation models (DEMs) of U.S. coastal regions. 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. Please see NGDC's corresponding DEM Footprints map 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 Geophysical Data Center. 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. Layers available in the map service: Layers 1-4: DEMs by Category (includes various DEMs, both hosted at NGDC, and elsewhere on the web); Layers 6-11: NGDC DEM Projects (DEMs hosted at NGDC, color-coded by project); Layer 12: All NGDC Bathymetry DEMs (All bathymetry or bathy-topo DEMs hosted at NGDC).

        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            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:
        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:
        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:
        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.

                description:  The data were visually inspected with Fledermaus and ArcGIS for identification and editing of data anomalies. Datasets were compared with overlapping datasets to ensure data consistency. In some cases, overlapping data were edited to ensure a smooth transition between adjacent datasets.

                  DateTime:  2012-12-15T00:00:00
            processStep:  (LE_ProcessStep)
                description:  ASCII 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.

            processStep:  (LE_ProcessStep)
                description:  The DEM was reviewed qualitatively for any noticeable artifacts introduced during the gridding process using imagery and other ancillary data. If necessary, problematic source data were edited and the an updated grid was created.
