Summary
Abstract:
ABSTRACT: NOAA's National Geophysical Data Center (NGDC) 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 modeling 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. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including NGDC, the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to the vertical tidal datum of Mean High Water (MHW) and horizontal datum of World Geodetic System 1984 (WGS84). Grid spacings for the DEMs range from 1/3 arc-second (~10 meters) to 3 arc-seconds (~90 meters).

Quality
LOGICAL CONSISTENCY REPORT: 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.
COMPLETENESS REPORT: NGDC made every effort to obtain all available digital topographic and bathymetric datasets in the region for use in building the DEM.
HORIZONTAL POSITIONAL ACCURACY REPORT: The horizontal 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: 30 meters along the coast and greater inland. Positional accuracy of input topographic datasets limits accuracy of corresponding cell values in DEM. USGS NED DEM: 10 to 15 meters. SRTM DEM: 10 to 20 meters. Where present, SRTM data supplant NED data values in the DEM. DEM cell-value relative-contribution factors: NED: 1, SRTM: 10, OCS ENC land elevations: 100. Bathymetry: 30 to several tens of meters. Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in the DEM. NGDC multibeam sonar: about 10 meter. 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 NOS soundings. Where present, multibeam sonar supplant NOS hydrographic sounding data values in the DEM. DEM cell-value relative-contribution factors: multibeam swath sonar survey data: 10, NOS hydrographic soundings: 1.
VERTICAL POSITIONAL ACCURACY REPORT: 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: 10 to 15 meters. Vertical accuracy of input topographic datasets limits accuracy of corresponding cells in DEM. USGS NED DEM: 7 and 15 meters. SRTM DEM: 16 meters. DEM cell relative-contribution factors: SRTM: 10, NED: 1, OCS ENC land elevations: 100. Bathymetry: 0.3 meters to 5% of water depth. Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cells in DEM. GPS-navigated NOS soundings: about 0.1 meter. 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: several meters. DEM cell relative-contribution factors: NOS hydrographic soundings: 1, multibeam swath sonar survey data: 10. Gridding interpolation to determine cell values between sparse NOS hydrographic soundings in deep water degrades the vertical accuracy of deep-water elevations.
LINEAGE/PROCESS STEP:
PROCESS DESCRIPTION: All datasets obtained by NGDC were converted to common horizontal and vertical datums of WGS84 geographic and Mean High Water, respectively, using FME. They were also converted to common file format, ESRI point shapefiles, for visualization and inspection.
LINEAGE/PROCESS STEP:
PROCESS 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.
LINEAGE/PROCESS STEP:
PROCESS DESCRIPTION: xyz files of the bathymetric data were surfaced using GMT's 'surface' tool onto a 3 arc-second grid that interpolated to fill empty cells. Points extracted every 30 meters along the coastline were also included to ensure that the bathymetric grid reached zero at the coast. The resulting Arc ASCII grid was imported into ArcGIS and clipped to the coastline to remove values over land.
LINEAGE/PROCESS STEP:
PROCESS DESCRIPTION: NGDC multibeam swath sonar data were gridded at 1 arc-second using MB-System's 'mbgrid' tool; this pre-gridding permitted vertical datum conversion to MHW. The resulting Arc ASCII grid was converted to an Arc raster in ArcCatalog, then converted again to an ESRI shape file and shifted to MHW using FME. The resulting point data were consistent with overlapping NOS hydrographic soundings, though providing significantly greater seafloor resolution
LINEAGE/PROCESS STEP:
PROCESS 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.
LINEAGE/PROCESS STEP:
PROCESS DESCRIPTION: The 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.
