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 (WGS 84). 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 and Applied Imagery QT Modeler 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 DEM cell size and the accuracy of the input datasets used to determine corresponding cell values. Topography, only one dataset was used: NASA SRTM DEM: 30 meters. DEM cell-value relative-contribution factors: SRTM: 10. Bathymetry: a few tens of meters to several hundreds of meters. Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in DEM. Recent NOS hydrogarphic data: about 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: tens to several hundreds of meters. NGDC multibeam sonar: about 10 meters. Trackline and ENC sounding data are limited by sparseness of deep-water soundings: a few hundreds of meters. Where present, recent NOS hydrographic survey data and NGDC multibeam supplant early 20th-centruy NOS hydrographic sounding data and NGDC marine trackline data values in the DEM. DEM cell-value relative-contribution factors: NOS hydrographic soundings: 0.1, NGDC Multibeam: 0.1, Trackline: 0.1.
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, only one dataset was used: NASA SRTM DEM: 10 to 16 meters. DEM cell relative-contribution factors: NED: 10. Bathymetry: 30 meters meters to 5% of water depth. Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cells in DEM. GPS-navigated NGDC multibeam sonar and marine trackline geophysics data: about 0.1 meter. Early 20th-century NOS hydrographic soundings and some NGDC marine trackline geophysics data are limited by sparseness of deep-water soundings, and potentially large position accuracy of pre-satellite (i.e., GPS) navigation: several tens of meters. NGDC multibeam sonar: about 0.1 meter. Where present, recent NOS hydrographic data and NGDC multibeam data supersede early 20th-centruy NOS hydrographic sounding data values and older NGDC marine trackline geophysics data in DEM. DEM cell relative-contribution factors: NOS hydrographic soundings: 0.1, NGDC trackline soundings: 0.1, NGDC multibeam: 0.1. Gridding interpolation to determine cell values between sparse NOS hydrographic soundings and between NGDC marine trackline geophysics data degrades the vertical accuracy of elevations.
LINEAGE/PROCESS STEP:
PROCESS DESCRIPTION: All datasets obtained by NGDC were converted to common horizontal and vertical datums of NAD 83/WGS 84 geographic and Mean High Water, respectively, using FME or ArcGIS. They were also converted to common file format, ESRI point shapefiles or digital rasters, for visualization and inspection.
LINEAGE/PROCESS STEP:
PROCESS DESCRIPTION: Datasets were visually inspected with ArcGIS and QT Modeler 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 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 imported into ArcGIS and clipped to the coastline to remove values over land.
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. Gridding was performed in quadrants, each with a 5% data buffer. The grids were imported in ArcGIS and seamlessly merged to create the final DEM.
LINEAGE/PROCESS STEP:
PROCESS DESCRIPTION: The DEM was quantitatively 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.
