Resource Abstract:
NOAA's National Centers for Environmental Information (NCEI) is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions. These integrated bathymetric-topographic DEMs are used to support individual coastal States as part of the Pacific Marine Environmental Laboratory's (PMEL) efforts to support NOAA's tsunami forecast system and for tsunami inundation modeling, improve community preparedness and hazard mitigation. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources including: NOAA; the U.S. Geological Survey (USGS); and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to the vertical datum of MHW and horizontal datum of World Geodetic System 1984 geographic (WGS 84). Grid spacing for the DEM is 1/3 arc-second (~10 meters).

Resource Abstract:
This is an ArcGIS image 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.

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description  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: 10 meters. Positional accuracy of input topographic datasets limits accuracy of corresponding cell values in DEM. NED topography: 10 meters, Lidar: less than 1 meter. DEM cell-value relative-contribution factors: Lidar: 1000 to 10, Topographic DEM: 10, NED: 1. Bathymetry: less than 1 meter to a few kilometers. Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in DEM. USACE: ~ 5 meters, Multibeam data: ranging from less than 1 meter to 10 meters . DEM cell-value relative-contribution factors: USACE and NOS hydrographic surveys: 100, Multibeam: 1, Bathymetric lidar: 10, Bathymetric pre-surface: 1.
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description  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: 9 cm to 1 meter. Vertical accuracy of input topographic datasets limits accuracy of corresponding cells in DEM. DEM cell-value relative-contribution factors: Lidar: 1000 to 10, Topographic DEM: 10, NED: 1. Bathymetry: less than 1 meter to 5% of water depth. Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cells in DEM. NOS hydrographic surveys: about 1% of water depth. DEM cell-value relative-contribution factors: USACE and NOS hydrographic surveys: 100, Multibeam: 1, Bathymetric lidar: 10, Bathymetric pre-surface: 1. Gridding interpolation to determine cell values between sparse soundings in deep water degrades the vertical accuracy of corresponding elevations.
Completeness Commission
evaluation Method Description  NCEI made every effort to obtain all available digital topographic and bathymetric datasets in the region for use in building the DEM.
ConceptualConsistency
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 superceded prior to building the DEM.
