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 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce DEM Information dem.info@noaa.gov pointOfContact asNeeded http://www.ngdc.noaa.gov/mgg/image/inundation/pers/tigp/elfin_cove_ak.jpg Perspective view of DEM JPEG 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 > Land Surface > Topography > Terrain Elevation Earth Science > Land Surface > Topography > Topographical Relief Earth Science > Oceans > Coastal Processes > Coastal Elevation theme NASA/GCMD Earth Science Keywords DEM > Digital Elevation Model theme NASA/GCMD Platform Keywords DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce WDC/MGG, BOULDER > World Data Center for Marine Geology and Geophysics, Boulder theme NASA/GCMD Data Center Keywords V: < 1 meter theme NASA/GCMD Data Resolution Keywords Coastal Relief Gridded elevations Integrated bathymetry and topography theme Uncontrolled Continent > North America > United States of America > Alaska Ocean > Pacific Ocean > North Pacific Ocean Ocean > Pacific Ocean > North Pacific Ocean > Gulf of Alaska Vertical Location > Land Surface Vertical Location > Sea Floor place NASA/GCMD Location Keywords Southeast Alaska place Uncontrolled Not to be used for navigation.

Positional accuracy of input topographic datasets limits accuracy of corresponding cell values in DEM. USGS SRTM DEM: 15 to 30 meters. ASTER DEM: 30 meters. DEM cell-value relative-contribution factors: SRTM: 1. ASTER: 1. Bathymetry: several hundred meters. Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in DEM. NOS hydrographic surveys, NOS BAGs, NOS ASCII grids, and USACE surveys (primarily in dredged shipping channels): about 1 meter. Early 20th- century NOS hydrographic soundings are limited by sparseness of deep-water soundings, and potentially large position accuracy of pre- satellite (i.e., GPS) navigation: tens to several hundreds of meters. Morphologic change in inland rivers and along the coast also degrades the positional accuracy of NOS soundings. Where present, NOS BAGs, NOS ASCII grids, and USACE survey data supplant NOS hydrographic sounding data values in the DEM. DEM cell-value relative-contribution factors: ENC soundings: 100, USACE surveys: 100, NOS BAGs: 100, NOS ASCII grid: 100, NGDC multibeam sonar surveys: 100, NOS hydrographic soundings: 10, City of Juneau harbor surveys: 10, CHS gridded bathymetry: 1, Trackline soundings: 0.1. 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. Topography: 15 to 20 meters. Vertical accuracy of input topographic datasets limits accuracy of corresponding cells in DEM. SRTM DEM: 16 meters. ASTER DEM: 20 meters. DEM cell relative-contribution factors: SRTM: 1 ASTER: 1. Bathymetry: 2 meters to 5% of water depth. Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cells in DEM. GPS-navigated NOS, NOS BAG and ASCII; and USACE surveys (primarily in dredged shipping channels): about 0.1 meter. Early 20th-century NOS hydrographic soundings are limited by sparseness of deep-water soundings, and potentially large positional accuracy of pre-satellite (i.e., GPS) navigation: several meters. Where present, USACE survey data supersede NOS hydrographic sounding data values in DEM. DEM cell-value relative-contribution factors: ENC soundings: 100, USACE surveys: 100, NOS BAGs: 100, NOS ASCII grid: 100, NGDC multibeam sonar surveys: 100, NOS hydrographic soundings: 10, City of Juneau harbor surveys: 10, CHS gridded bathymetry: 1, Trackline soundings: 0.1. 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 Higher High Water, respectively, using Proj4, and GDAL. They were also converted to common file formats, ESRI point shapefiles or xyz, for visualization and inspection. 2012-07-04T00:00:00 Barry W.

Datasets were then compared with overlapping datasets to ensure data consistency. 2012-07-05T00:00:00 xyz files of the bathymetric data were surfaced using GMT's 'surface' tool onto a 8 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 using GDAL to remove values over land. 2012-08-02T00:00:00 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 with a 5% data buffer. The grid was imported in ArcGIS to create the final DEM. 2012-08-03T00:00:00 Source Contribution: hydrographic surveys downloaded from web site. ; Source Type: online NOS Hydrographic Surveys 2009-01-01 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 1883-01-01 2009-01-01 Source Contribution: Hydrographic surveys downloaded from web site. ; Source Type: online USACE Hydrographic Surveys 2010-01-01 publication U.S. Army Corps of Engineers, Alaska District originator Citation URL http://www.poa.usace.army.mil/ USACE Alaska District Hydrographic Surveys Digital database of hydrographic surveys in Alaska download 1999-01-01 2008-01-01 Source Contribution: Extracted hydrographic soundings ; Source Type: online Electronic Navigational Charts 2009-01-01 publication DOC/NOAA/NOS/OCS > Office of Coast Survey, National Ocean Service, NOAA, U.S. Department of Commerce originator Citation URL http://www.nauticalcharts.noaa.gov/mcd/enc/index.htm OCS Electronic Navigational Charts Digital database of NOAA nautical chart information. download 1977-01-01 2009-01-01 Source Contribution: multibeam surveys downloaded from web site. ; Source Type: online NGDC Multibeam Surveys 2009-01-01 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/multibeam.html NGDC Multibeam Survey Database Digital database of NGDC multibeam surveys. download 1994-01-01 2009-01-01 Source Contribution: gridded topographic data downloaded from web site. ; Source Type: on web Shuttle Radar Topography Mission (SRTM) 2009-01-01 publication NASA > National Aeronautics and Space Administration originator Citation URL http://srtm.usgs.gov/ Shuttle Radar Topography Mission global topography download 2000-01-01 Source Contribution: gridded topographic data downloaded from web site. ; Source Type: on web Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) 2009-01-01 publication NASA > National Aeronautics and Space Administration originator Citation URL lpdaac.usgs.gov Advanced Spaceborne Thermal Emission and Reflection Radiometer global topography download 2009-01-01 Source Contribution: tidal information table from which vertical datum adjustment information are interpreted; Source Type: online Bench Mark Data Sheets with Tidal Datum References 2010-01-01 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 Sheets information documentDigital 1983-01-01 2001-01-01 Source Contribution: Canadian Hydrographic Service tide station datums ; Source Type: digital files via email CHS Tidal Datum References 2010-01-01 publication Canadian Hydrographic Service originator Citation URL http://chs-shc.gc.ca/ Canadian Hydrographic Service Tidal Datums Tidal datum references for Canadian tide stations download 2010-01-01 Source Contribution: gps survey data obtained from UAF ; Source Type: online UAF Elfin Cove GPS 2012-01-01 publication University of Alaska at Fairbanks originator 2012-01-01 2012-01-01 Source Contribution: Hydrographic surveys downloaded from web site. ; Source Type: online USACE Hydrographic Surveys 2011-01-01 publication U.S. Army Corps of Engineers, Alaska District originator Citation URL http://www.poa.usace.army.mil/ USACE Alaska District Hydrographic Surveys Digital database of hydrographic navigation chanel surveys in Alaska download 2011-01-01 2011-01-01 annually 2013-08-03 This metadata was automatically generated from the Content Standard for Digital Geospatial Metadata: Extensions for Remote Sensing Metadata standard (version FGDC-STD-012-2002) using the 2012-08-07. f version of the FGDC RSE to ISO 19115-2 transform for DEMs. Last Translation from FGDC 2012-08-07T15:55:51.441-06:00 Last Metadata Review Date: 2012-08-03 Kelly Carignan DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce kelly.carignan@noaa.gov pointOfContact Light Detection and Ranging Multibeam Swath Bathymetry System Sound Navigation and Ranging Tsunami Inundation Gridding Project Digital Elevation Model
