NOAA Tsunami Inundation DEMs
Port Alberni, Canada 1/3 arc-second DEM
NOAA's National Centers for Environmental Information 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 warning 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.
Developed for the Pacific Marine Environmental Laboratory (PMEL), NOAA Center for Tsunami Research program in support of NOAA's tsunami forecasting and warning efforts.

NOAA Coastal Inundation DEMs
Named by primary coastal city, state in DEM.
NOAA's National Centers for Environmental Information (NCEI) is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions to support inundation modeling and community mitigation and resiliency efforts. These integrated bathymetric-topographic DEMs support tsunami forecast and warning from NOAA's Tsunami Warning Centers. The DEMs are used in the MOST (Method of Splitting Tsunami) model developed by NOAA's Pacific Marine Environmental Laboratory (PMEL) to simulate tsunami generation, propagation, and inundation. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including federal and academia data archived at NCEI, 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). Depending on the user requirements and available data, grid spacings for the DEMs range from 1/3 arc-second (~10 meters) to 3 arc-seconds (~90 meters).

The DEM Global Mosaic is an image service providing a global, seamless bathymetry/topography mosaic that includes NCEI's ETOPO 2022, NCEI's Continuously Updated DEM (CUDEM), and other NCEI-stewarded DEMs, along with regional grids such as IBCAO, IBCSO and the Hawaiian Island Multibeam Synthesis (University of Hawaii). This service provides elevation/depth values in meters; for a visualization of the data, please see the related DEM Global Mosaic (Color Shaded Relief) service. There are 5 related image services providing access to Digital Elevation Models: DEM Mosaic (Individual DEMs), DEM Global Mosaic (Elevation Values), DEM Global Mosaic (Color Shaded Relief), CUDEM Mosaic (Elevation Values), and CUDEM Mosaic (Color Shaded Relief). NCEI 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. This service is a general-purpose global, seamless bathymetry/topography mosaic. It combines DEMs from a variety of near sea-level vertical datums, such as mean high water (MHW), mean sea level (MSL), and North American Vertical Datum of 1988 (NAVD88). No conversion/harmonization of vertical datums was performed. Because the mosaic contains 'overviews' for performance, individual DEMs cannot be separated from the others. Individual DEMs, or smaller subsets, are available in the companion DEM Mosaic (Individual DEMs) image service. By default, the DEMs are drawn in order of cell size, with higher-resolution grids displayed on top of lower-resolution grids. If overlapping DEMs have the same resolution, the newer one is shown. Please see NCEI's corresponding DEM Footprints feature service for polygon footprints and more information about the individual DEMs used to create this composite view.

NOAA National Centers for Environmental Information
NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.

Horizontal Positional Accuracy Report
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. CDSM topography: 30 meters, Lidar: less than 1 meter. Bathymetry: less than 1 meter to a few kilometers. Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in DEM. Multibeam data: ranging from less than 1 meter to 10 meters .
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: 9 cm to 1 meter. Vertical accuracy of input topographic datasets limits accuracy of corresponding cells in DEM. Bathymetry: less than 1 meter to 5% of water depth. Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cells in DEM. Gridding interpolation to determine cell values between sparse soundings in deep water degrades the vertical accuracy of corresponding elevations.
NCEI 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 superceded prior to building the DEM.
All datasets obtained by NCEI were transformed to common horizontal and vertical datums of WGS 84 geographic and NAVD88, respectively, using constant offsets and transformation parameters in NOAAs VDatum software. They were also converted to common file format 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.
2015-10-28T00:00:00
Older and low-resolution data were clipped to newer and high-resolution data where inconsistencies occured in overlap areas of the datasets.
2015-10-28T00:00:00
Topographic data was filtered to remove water surface points where they existed
2015-10-28T00:00:00
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 5 meters along the coastline were also included to ensure that the bathymetric grid reached zero at the coast. The resulting Arc ASCII grid was clipped to the coastline to remove values over land using GDAL.
2015-10-30T00:00:00
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.
2015-11-12T00:00:00
The DEM was quantitatively evaluated by comparing with source datasets.
