- 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). Cell size ranges from 1/3 arc-second (~10 meters) to 36 arc-seconds (~1 km). DEMs built by PMEL's NOAA
Center for Tsunami Research (formerly NOAA Center for Tsunami Inundation Mapping Efforts) are available for download from
the web site.
- Purpose:

- Data Quality Information:
-
- Logical Consistency Report:
- Datasets are 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 are selected for use in that region. Elevations in the older and/or lower-resolution
datasets are deleted prior to building the DEMs.
- Completeness Report:
- NGDC makes every effort to obtain all available digital topographic and bathymetric datasets in each region for use in building
the DEMs.
- Positional Accuracy:
-
- Horizontal Positional Accuracy:
-
- Horizontal Positional Accuracy Report:
- The horizontal accuracy of bathymetric and topographic features in the DEMs are dependent upon DEM cell size and the accuracy
of input datasets used to determine corresponding cell values.
- Vertical Positional Accuracy:
-
- Vertical Positional Accuracy Report:
- The vertical accuracy of bathymetric and topographic features in the DEM is dependent upon DEM cell size and the accuracy
of input datasets used to determine corresponding cell values. Gridding interpolation to determine 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 are converted to common horizontal and vertical datums of WGS84 geographic and Mean High Water,
respectively, using FME. They are also converted to common file format, ESRI point shapefiles, for visualization and inspection.

- Process Step:
-
- Process Description:
- Datasets are visually inspected with ArcGIS for identification and editing of data anomalies. Datasets are then compared with
overlapping datasets to ensure data consistency.
- Process Date:
- 20081031
- Process Step:
-
- Process Description:
- xyz files of the bathymetric data are surfaced using GMT's 'surface' tool onto a 1 arc-second grid that is interpolated to
fill empty cells. Points extracted every 10 meters along the coastline are also included to ensure that the bathymetric grid
reaches zero at the coast. The resulting Arc ASCII grid is imported into ArcGIS and clipped to the coastline to remove values
over land.
- Process Date:
- 20081031
- Process Step:
-
- Process Description:
- xyz files for each input dataset are 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 is given to more recent, higher-accuracy
datasets. Gridding is typically performed in quadrants, each with a 5% data buffer. The grids are imported in ArcGIS and seamlessly
merged to create the final DEM.
- Process Date:
- 20081031
- Process Step:
-
- Process Description:
- The DEMs are quantitatively evaluated by comparing with source datasets and with elevation values extracted from NGS geodetic
monuments. They are 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 DEMs.
