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). Developed for the University of Alaska at Fairbanks (UAF), Geophysical Institute for tsunami and coastal inundation modeling efforts for the State of Alaska. completed NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact NOAA National Centers for Environmental Information DEM Information dem.info@noaa.gov pointOfContact notPlanned https://www.ncei.noaa.gov/themes/custom/ncei/logo.svg NOAA logo SVG Earth Science > Oceans > Bathymetry/Seafloor Topography > Seafloor Topography Earth Science > Oceans > Bathymetry/Seafloor Topography > Bathymetry Earth Science > Oceans > Bathymetry/Seafloor Topography > Water Depth Earth Science > Oceans > Coastal Processes > Coastal Elevation {{Add other GCMD science ketywords}} theme Global Change Master Directory (GCMD) Science Keywords 2024 revision 19 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2024.

DEM cell-value relative-contribution factors: Topographic Lidar:1000 or 100, USACE:100, USGS NED:10, NCEI DEMs:1000, Bathymetric surface:10, NOS:1, SRTM: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. DEM cell-value relative-contribution factors: Topographic Lidar:1000 or 100, USACE:100, USGS NED:10, NCEI DEMs:1000, Bathymetric surface:10, NOS:1, SRTM:1.. Gridding interpolation to determine cell values between sparse data points 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) 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 NCEI were converted to common horizontal and vertical datums of WGS 84 geographic and Mean Higher High Water, respectively, based on tide station information. They were also converted to common file format, ESRI point shapefiles, for visualization and inspection. 2020-07-01T00:00:00 NOAA National Centers for Environmental Information DEM Information dem.info@noaa.gov processor ENC soundings Electronic Navigational Chart (ENC) digital soundings 2017-04-13 distribution OCS > NOAA Office of Coast Survey originator http://www.nauticalcharts.noaa.gov/mcd/enc/index.htm Electronic Navigational Chart (ENC) soundings ENC soundings extracted from NOS charts download 2018-12-01 2020-01-01 NOS hydrographic survey data NOS Hydrographic Surveys 2008-01-01 publication DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce originator Citation URL http://www.ngdc.noaa.gov/mgg/bathymetry/hydro.html NOS Hydrographic Survey Database Digital database of NOS hydrographic surveys that date back to the late 19th century. download 2007-01-01 2009-01-01 Tidal information table from which vertical datum adjustment information are interpreted Bench Mark Data Sheet with Tidal Datum References 2018-02-16 publication DOC/NOAA/NOS National Ocean Service, NOAA, U.S. Department of Commerce originator Citation URL http://tidesandcurrents.noaa.gov/station_retrieve.shtml Tides and Currents Station Selection Bench Mark Data Sheet for stations #9455963, #9455934, #9455920, #9455912, #9455866, #9455869, #9455777, #9455760, #9455735, #9455711, #9455732, #9455653, #9455606, #9455558, #9455595, #9455517, #9455500, #9456717, #9455145, #9455146, #9455204, #9455159, #9455151, #9455128, #9455120, #9455090 information documentDigital 1983-01-01 2018-11-01 Topographic Lidar DEM 2015 Lidar DEM: Municipality of Anchorage, AK 2017-12-14 publication Municipality of Anchorage, AK; Merrick Co; McElhanney originator Citation URL https://elevation.alaska.gov/ DGGS Elevation Portal Alaska Department of Natural Resources, Divison of Geological and Geophysical Surveys, Data Download and Visualization Services download 2015-05-10 2015-05-31 Gridded smoothsheet bathymetry AFSC/RACE/GAP/Zimmermann: Cook Inlet bathymetry of Alaska Grid 2014-04-01 publication National Marine Fisheries Service - Alaska Fisheries Science Center originator Harbor condition survey Harbor condition survey for Anchorage and Cook Inlet 2012-01-01 publication US Army Corp of Engineers (USACE) Alaska District originator http://www.poa.usace.army.mil/Home.aspx Survey data of Anchorage and Cook Inlet Hydrographic Sounding at intervals and topographic data points along Project design lines spaced at specific intervals. download 2012-01-01 2020-01-01 Digital Elevation Models (DEMs) 1/3rd and 1 arc-second Digital Elevation Models (DEMs) - USGS National Map 3DEP Downloadable Data Collection 2020-01-01 publication USGS originator Citation URL https://www.usgs.gov/core-science-systems/ngp/tnm-delivery USGS The National Map The National Map Data Download and Visualization Services download 2013-01-01 2019-01-01 Topographic Lidar DTM MatSu Matanuska Area Point Clouds 2012-06-27 publication Alaska Dept. of Natural Resources originator Citation URL https://elevation.alaska.gov/ DGGS Elevation Portal Alaska Department of Natural Resources, Divison of Geological and Geophysical Surveys, Data Download and Visualization Services download 2011-05-10 2011-10-10 repository 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.
