        abstract:  NOAA's National Centers for Environmental Information is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions. These integrated bathymetric-topographic DEMs are used to support tsunami forecasting and warning efforts at the NOAA Center for Tsunami Research, Pacific Marine Environmental Laboratory (PMEL). The DEMs are part of the tsunami forecast system SIFT (Short-term Inundation Forecasting for Tsunamis) currently being developed by PMEL for the NOAA Tsunami Warning Centers, and are used in the MOST (Method of Splitting Tsunami) model developed by PMEL to simulate tsunami generation, propagation, and inundation.
        purpose:  Developed for the Pacific Marine Environmental Laboratory (PMEL), NOAA Center for Tsunami Research program in support of NOAA's tsunami forecasting and warning efforts.

                        description:  An image service providing access to bathymetric/topographic digital elevation models stewarded at NOAA's National Centers for Environmental Information. Either individual DEMs or small subsets can be accessed through this service.
                        function:  (CI_OnLineFunctionCode) search

        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).

            measureDescription:  Datasets were visually compared internally and externally (with other overlapping datasets and satellite images and nautical charts) in ESRI ArcGIS, QT Modeler and MB-System 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.

        lineage:  (LI_Lineage)
            processStep:  (LE_ProcessStep)
                description:  Datasets were visually inspected with ArcGIS, GlobalMapper and MB-System for identification and editing of data anomalies, including but not limited to inconsistencies between overlapping or adjacent datasets, 'noisy' data, etc.
                dateTime:
                  DateTime:  2016-04-01T00:00:00
            processStep:  (LE_ProcessStep)
                description:  All data were converted to ASCII XYZ files. A 3 arc-second bathymetric 'pre-surface' grid of bathymetric data (near- and far-shore multibeam and trackline soundings) was generated using a tensioned spline algorithm within GMT's 'surface' utility that interpolated depth values to areas where data were sparse and/or nonexistent. The bathymetric 'pre-surface' was then imported into ArcGIS and clipped to the coastline of Niue to remove values over land. The clipped 'pre-surface' was then converted to ASCII XYZ point data.

            processStep:  (LE_ProcessStep)
                description:  Seafloor contours (300, 600 and 900 meters) of Niue's fore-reef slope were digitized manually and converted to an ASCII XYZ file using ArcGIS.

            processStep:  (LE_ProcessStep)
                description:  The final integrated 3 arc-second topo-bathy DEM was created using MB-System's 'mbgrid' tool, which utilizes a high-tension spline interpolation method to fill grid cells with no input elevation values. The bathymetric surface points, digitized contours, GEBCO08 grid and topographic data were used as source datasets in the spline gridding algorithm. Preferential weighting was given to more recent, higher-accuracy datasets.
                dateTime:
                  DateTime:  2016-04-01T00:00:00
            processStep:  (LE_ProcessStep)
                description:  The DEM was qualitatively evaluated to identify any artifacts that may have been introduced during the gridding process. As necessary, the data were edited and the gridding routine was re-run. Once the DEM was deemed suitable, it was compared to nautical charts to ensure data consistency.
