These integrated bathymetric-topographic DEMs were developed for NOAA Coastal Survey Development Laboratory (CSDL) through the American Recovery and Reinvestment Act (ARRA) of 2009 to evaluate the utility of the Vertical Datum Transformation tool (VDatum), developed jointly by NOAA's Office of Coast Survey (OCS), National Geodetic Survey (NGS), and Center for Operational Oceanographic Products and Services (CO-OPS). Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including NGDC, the U.S. Coastal Services Center (CSC), the U.S. Office of Coast Survey (OCS), the U.S. Army Corps of Engineers (USACE), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to the vertical tidal datum of North American Vertical Datum of 1988 (NAVD 88) or Mean High Water (MHW) and horizontal datum of North American Datum of 1983 (NAD 83). Cell size ranges from 1/3 arc-second (~10 meters) to 1 arc-second (~30 meters). The NOAA VDatum DEM Project was funded by the American Recovery and Reinvestment Act (ARRA) of 2009 (http://www.recovery.gov/). Purpose: Developed for the Office of Coast Survey (OCS), NOAA Coastal Survey Development Laboratory (CSDL) in support of NOAA's Vertical Datum Transformation tool (VDatum).

Either individual DEMs or small subsets can be accessed through this service. Function: Online function code: search Role: Role code: publisher 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.

Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in DEM. CSC Lidar: 0.75 meters. Early 20th-century NOS hydrographic soundings are limited by sparseness of deep-water soundings, and potentially large position accuracy of pre-satellite (i.e., GPS) navigation: tens to several tens of meters. Morphologic change in inland rivers and along the coast also degrades the positional accuracy of DEM features.

Gridding interpolation to determine cell values between sparse NOS hydrographic soundings in deep water degrades the vertical accuracy of deep-water elevations. Result: missing Report: Completeness commission: Evaluation method description: NGDC made every effort to obtain all available digital topographic and bathymetric datasets in the region for use in building the DEM. Result: unknown Report: Conceptual consistency: Measure description: 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. Result: unknown Lineage: Lineage: Process step: Process Step: Description: All datasets obtained by NGDC were converted to common horizontal and vertical datums of NAD 83 geographic and NAVD 88, respectively, using FME, Proj4 and VDatum transformation tool.

Love Organisation name: NOAA National Centers for Environmental Information Role: Role code: pointOfContact Process step: Process Step: Description: Datasets were visually inspected with ArcGIS for identification and editing of data anomalies. Datasets were then compared with overlapping datasets to ensure data consistency. Date and time: 2009-09-10T00:00:00 Process step: Process Step: Description: Coastline datasets were merged and adjusted to fit satellite imagery. Date and time: 2009-10-24T00:00:00 Process step: Process Step: 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 10 meters along the coastline were also included to ensure that the bathymetric grid reached zero at the coast. The resulting Arc ASCII grid was clipped to the coastline to remove values over land. Date and time: 2009-11-14T00:00:00 Process step: Process Step: Description: 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. Gridding was performed with a 5% data buffer. Date and time: 2010-01-23T00:00:00 Process step: Process Step: Description: The NAVD 88 DEM was quantitatively evaluated by comparing with source datasets and with elevation values extracted from NGS geodetic monuments. It was visually evaluated by converting to UTM-zone coordinates (units of meters horizontally and vertically) and then creating a slope grid to identify gridding artifacts in the DEM. Date and time: 2010-02-10T00:00:00 Process step: Process Step: Description: A conversion grid that models the relationship between NAVD 88 and MHW was created using data points and the VDatum transformation tool. This conversion grid was added to the NAVD 88 DEM to generate the MHW DEM.
