Some modeling utilizes structured, square-cell DEMs, while others utilize unstructured grids that have no regular cell size or pattern. Usually, these different DEM types are developed independently, even though they are built from the same source bathymetric and topographic datasets. The National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), has developed two bathymetric-topographic square-celled DEMs and one bathymetric-topographic unstructured DEM of southern Louisiana. The DEMs were developed for the Hurricane Forecast Improvement Project (HFIP), with the purpose of developing a new methodology for unstructured grid production from structured square-celled grids. The 1/3 arc-second DEM referenced to North American Vertical Datum of 1988 (NAVD 88) was carefully developed and evaluated. A NAVD 88 to mean high water (MHW) 1/3 arc-second conversion grid derived from VDatum project areas was created to model the relationship between NAVD 88 and MHW in the southern Louisiana region. NGDC combined the NAVD 88 DEM and the conversion grid to develop a 1/3 arc-second MHW DEM. The NAVD 88 DEM was generated from diverse digital datasets in the region. The DEMs were developed to be used for storm surge inundation and sea level rise modeling. The source bathymetric and topographic datasets used in the development of the NAVD 88 DEM were utilized along with the NAVD 88 DEM and derivative grids to develop the NAVD 88 unstructured DEM. purpose: Developed for the Hurricane Forecast Improvement Project (HFIP) status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) organisationName: NOAA National Centers for Environmental Information positionName: DEM Information contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: dem.info@noaa.gov role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded graphicOverview: (MD_BrowseGraphic) fileName: https://maps.ngdc.noaa.gov/thumbnails/DEM/1521.png fileDescription: Thumbnail of DEM fileType: PNG descriptiveKeywords: (MD_Keywords) keyword: Earth Science > Oceans > Bathymetry/Seafloor Topography > Seafloor Topography keyword: Earth Science > Oceans > Bathymetry/Seafloor Topography > Bathymetry keyword: Earth Science > Oceans > Bathymetry/Seafloor Topography > Water Depth keyword: Earth Science > Land Surface > Topography > Terrain Elevation keyword: Earth Science > Land Surface > Topography > Terrain Elevation > Topographical Relief Maps keyword: Earth Science > Oceans > Coastal Processes > Coastal Elevation type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Science and Services Keywords date: (unknown) descriptiveKeywords: (MD_Keywords) keyword: Models/Analyses > DEM > Digital Elevation Model type: (MD_KeywordTypeCode) platform thesaurusName: (CI_Citation) title: NASA/GCMD Platform Keywords date: (unknown) descriptiveKeywords: (MD_Keywords) keyword: ICSU-WDS > International Council for Science - World Data System type: (MD_KeywordTypeCode) project thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Project Keywords date: (CI_Date) date: 2020-01-09 dateType: (CI_DateTypeCode) publication edition: 9.1 citedResponsibleParty: (CI_ResponsibleParty) organisationName: NASA Goddard Space Flight Center, Earth Science Data and Information System contactInfo: (CI_Contact) onlineResource: (CI_OnlineResource) linkage: https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords name: Global Change Master Directory (GCMD) Keywords description: The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

NCEI launched publicly on April 22, 2015. dateTime: DateTime: 2015-04-22T00:00:00 return to top dataQualityInfo: (DQ_DataQuality) scope: (DQ_Scope) level: (MD_ScopeCode) dataset report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Horizontal Positional Accuracy Report evaluationMethodDescription: 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: 10 meters due to cell size. Lidar: less than 5 meters. DEM cell-value relative-contribution factors: Louisiana Lidar, CSC Lidar: 100, Digitzed features: 1, Bathymetry: 5 to several tens of meters. Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in DEM. CSC Lidar: 0.75 meters. 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 tens of meters. Morphologic change in inland rivers and along the coast also degrades the positional accuracy of DEM features. DEM cell-value relative-contribution factors: CSC Coastal Lidar: 100, USACE hydrographic survey data: 5, NOS hydrographic soundings: 5, Digitized features: 1. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy Report evaluationMethodDescription: 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: 1 to 16 meters. Vertical accuracy of input topographic datasets limits accuracy of corresponding cells in DEM. Lidar: less than 1 meter. DEM cell relative-contribution factors: Louisiana Lidar, CSC Lidar: 100, Digitized features: 10. Bathymetry: 0.1 meters to 5% of water depth. Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cells in DEM. 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: several meters. DEM cell relative-contribution factors: CSC Coastal Lidar: 100, USACE hydrographic survey data: 5, NOS hydrographic soundings: 5, Digitized features: 1. Gridding interpolation to determine cell values between sparse NOS hydrographic soundings in deep water degrades the vertical accuracy of deep-water elevations. result: (missing) report: (DQ_CompletenessCommission) evaluationMethodDescription: NGDC made every effort to obtain all available digital topographic and bathymetric datasets in the region for use in building the DEM. result: (unknown) report: (DQ_ConceptualConsistency) measureDescription: 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. result: (unknown) lineage: (LI_Lineage) processStep: (LE_ProcessStep) description: All datasets obtained by NGDC were converted to common horizontal and vertical datums of NAD 83 geographic and NAVD 88, respectively, using Proj4 and VDatum transformation tool. They were also converted to common file format, ESRI point shapefiles, for visualization and inspection. dateTime: DateTime: 2010-08-28T00:00:00 processor: (CI_ResponsibleParty) individualName: Matthew R. Love organisationName: NOAA National Centers for Environmental Information role: (CI_RoleCode) pointOfContact processStep: (LE_ProcessStep) description: Datasets were visually inspected with ArcGIS for identification and editing of data anomalies. Datasets were then compared with overlapping datasets to ensure data consistency. dateTime: DateTime: 2010-09-01T00:00:00 processStep: (LE_ProcessStep) description: Coastline datasets were merged and adjusted to fit satellite imagery. dateTime: DateTime: 2010-09-24T00:00:00 processStep: (LE_ProcessStep) description: xyz files of the bathymetric data were surfaced using GMT's 'surface' tool onto a 1 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 netCDF grid was clipped to the coastline to remove values over land. dateTime: DateTime: 2010-09-30T00:00:00 processStep: (LE_ProcessStep) description: 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. dateTime: DateTime: 2010-10-20T00:00:00 processStep: (LE_ProcessStep) description: The NAVD 88 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. dateTime: DateTime: 2010-10-24T00:00:00 source: (LI_Source) description: Source Contribution: Hydrographic surveys provided to NGDC by CSDL ;
