NOAA Tsunami Inundation DEMs
Astoria, Washington - MHW - Version 2
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).
Developed for the Pacific Marine Environmental Laboratory (PMEL), NOAA Center for Tsunami Research program in support of NOAA's
tsunami forecasting and warning efforts.

publisher
This is a tiled map 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.

dataset
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: Positional accuracy of input topographic datasets limits accuracy
of corresponding cell values in DEM.
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. Vertical accuracy of input topographic datasets limits accuracy of corresponding
cells in DEM. Gridding interpolation to determine cell values between sparse NOS hydrographic soundings in deep water degrades
the vertical accuracy of deep-water elevations.
NGDC made every effort to obtain all available digital topographic and bathymetric datasets in the region for use in building
the DEM.
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.
All datasets obtained by NGDC were converted to common horizontal and vertical datums of WGS84 geographic and Mean High Water,
respectively, using proj4, gdal and VDatum. They were also converted to common file format, ESRI point shapefiles, for visualization
and inspection.

Datasets were visually inspected with ArcGIS for identification and editing of data anomalies. Datasets were then compared
with overlapping datasets to ensure data consistency.
2012-04-15T00:00:00
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 imported into ArcGIS and clipped to the coastline to remove values
over land.

xyz files of the topographic 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 imported into ArcGIS and clipped to the coastline to remove values
over water.
2012-04-16T00:00:00
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.
2012-04-17T00:00:00
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.
