These integrated bathymetric-topographic DEMs are used to support tsunami and coastal inundation mapping. 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 various vertical and horizontal datums depending on the specific modeling requirements of each State. For specific datum information on each DEM, refer to the appropriate DEM documentation. Cell sizes also vary depending on the specification required by modelers in each State, but typically range from 8/15 arc-second (~16 meters) to 8 arc-seconds (~240 meters).\r\n \r\n \r\n Developed for the University of Alaska at Fairbanks (UAF), Geophysical Institute for tsunami and coastal inundation modeling efforts for the State of Alaska.\r\n \r\n \r\n completed\r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n \r\n \r\n \r\n \r\n ncei.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/contact\r\n \r\n \r\n NCEI Contact Information\r\n \r\n \r\n Information for contacts at NCEI.\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n DEM Information\r\n \r\n \r\n \r\n \r\n \r\n \r\n dem.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n notPlanned\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/themes/custom/ncei/logo.svg\r\n \r\n \r\n NOAA logo\r\n \r\n \r\n SVG\r\n \r\n \r\n \r\n \r\n \r\n \r\n Earth Science > Oceans > Bathymetry/Seafloor Topography > Seafloor Topography\r\n \r\n \r\n Earth Science > Oceans > Bathymetry/Seafloor Topography > Bathymetry\r\n \r\n \r\n Earth Science > Oceans > Bathymetry/Seafloor Topography > Water Depth\r\n \r\n \r\n Earth Science > Oceans > Coastal Processes > Coastal Elevation\r\n \r\n \r\n {{Add other GCMD science ketywords}}\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Science Keywords\r\n \r\n \r\n \r\n \r\n 2024\r\n \r\n \r\n revision\r\n \r\n \r\n \r\n \r\n 19\r\n \r\n \r\n \r\n \r\n Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA)\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords\r\n \r\n \r\n GCMD Keyword Forum Page\r\n \r\n \r\n Global Change Master Directory (GCMD). 2024.

Points extracted every 2 meters along the coastline were also included to ensure that the bathymetric grid reached zero at the coast. The resulting grid was clipped to the coastline to remove values over land.\r\n \r\n \r\n 2019-04-20T00:00:00\r\n \r\n \r\n \r\n \r\n \r\n \r\n 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.
