In February 2012, USACE, Contracting Division contracted with The Atlantic Group to provide acquisition of Light Detection and Ranging (LiDAR) elevation data in the Hurricane and Storm Damage Risk Reduction System, St. Charles, Jefferson, Orleans, St. Bernard and Plaquemines Parishes, LA. This data will be used to support interior drainage modeling. LiDAR data should be collected to fully capture the total interior of the HSDRRS, including floodwalls, structures, and levees, and 200 feet outside of the HSDRRS to water's edge as appropriate. The project shall include capture of LiDAR data and the creation of digital elevation models (DEMs) derived from the LiDAR. The project area is approximately 418.4 sq. miles, including a 200' buffer. The purpose of the survey is to obtain measurements of the bare ground surface, as well as top surface feature elevation data for providing geometry input to USACE hydrodynamic and other numerical models as well as for performing economic related assessments. In addition to this 2 ft bare earth DEM data, the lidar point data, that these DEMs were created from are also available. These data are available for download here: https://coast.noaa.gov/dataviewer/#/lidar/search/where:ID=6350 Breaklines created from the lidar are also available for download in shp format at: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid12b/6350/breaklines The DEM and breakline products have not been reviewed by the NOAA Office for Coastal Management (OCM) and any conclusions drawn from the analysis of this information are not the responsibility of NOAA, OCM or its partners. purpose: The purpose of the survey is to obtain measurements of the bare ground surface, as well as top surface feature elevation data for providing geometry input to USACE hydrodynamic and other numerical models as well as for performing economic related assessments. credit: Paul Weyant, Patrick Robinson, Josh Hester status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: NOAA Office for Coastal Management Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) pointOfContact pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: NOAA Office for Coastal Management Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) custodian resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded graphicOverview: (MD_BrowseGraphic) fileName: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid12b/6350/supplemental/la2012_usace_new_orleans_m6350.kmz fileDescription: This graphic shows the lidar footprint for the 2012 USACE HSDRRS New Orleans project area. fileType: kmz descriptiveKeywords: (MD_Keywords) 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 Keywords date: (missing) edition: 17.0 descriptiveKeywords: (MD_Keywords) keyword: CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > LOUISIANA type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Location Keywords date: (missing) edition: 20.8 descriptiveKeywords: (MD_Keywords) keyword: ArcMap keyword: DEM keyword: ESRI keyword: HSDRRS keyword: Hurricane keyword: New Orleans District, Corps of Engineers keyword: Risk Reduction System keyword: bare earth type: (MD_KeywordTypeCode) theme descriptiveKeywords: (MD_Keywords) keyword: DEMs - partner (no harvest) type: (MD_KeywordTypeCode) project thesaurusName: (CI_Citation) title: InPort date: (inapplicable) resourceConstraints: (MD_LegalConstraints) useConstraints: (MD_RestrictionCode) otherRestrictions otherConstraints: Cite As: OCM Partners, [Date of Access]: 2012 USACE HSDRRS Lidar DEM: New Orleans [Data Date Range], https://www.fisheries.noaa.gov/inport/item/49431. resourceConstraints: (MD_Constraints) useLimitation: NOAA provides no warranty, nor accepts any liability occurring from any incomplete, incorrect, or misleading data, or from any incorrect, incomplete, or misleading use of the data.

Existing breakline data sets shall be used to the furthest extent possible to minimize manual collection of additional break lines. The breaklines compiled for the FEMA 2001/2003 LIDAR as well as the 1998 land and water interface polylines shall be used along the HSDRRS levees as necessary to support creation of final DEMs. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Horizontal Positional Accuracy evaluationMethodDescription: The data must meet the NSSDA RMSEr of 2.2 ft (0.67 m) and the NSSDA Accuracyr of 95% confidence level is 3.80 ft (1.16 m). Horizontal point accuracy is a function of angular origination of the pulse; IMU orientation; the scanner encoder and ranging function and will vary depending on the proposed point density selected for the collection. Statistically, the error is roughly 1/3 of the illuminated foot print on the ground and is a function of the beam divergences. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy evaluationMethodDescription: Based on the vertical accuracy testing conducted by The Atlantic Group, LLC using NSSDA methodology, the dataset tested 12.2 cm for vertical accuracy at 95% confidence level in open terrain. LiDAR vertical data accuracy determination shall employ the National Standard for Spatial Data Accuracy (NSSDA). Contracted to meet 18cm (RMSE) or better. result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Measure evaluationMethodDescription: Cloud Cover: 0 result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: The creation of Triangular Irregular Network (TIN) elevation models and apply linear interpolation procedures to generate the gridded DEMs at uniform post spacing. TIN post spacing should be smaller than the gridded DEM post spacing. The TIN models should be hydro enforced with breaklines of significant hydro features (> 100ft width) such as bayous, stream banks, or lakeAll data is complete to standards as specified. result: (missing) report: (DQ_ConceptualConsistency) nameOfMeasure: Conceptual Consistency evaluationMethodDescription: QC/QA process shall include reviews of flight alignments and completeness of supporting data. The USACE New Orleans district or its designee may perform additional QC/QA testing. The root mean square error (RMSE) is used to estimate both horizontal and vertical accuracy. RMSE is the square root of the average of the set of squared differences between dataset coordinate values and coordinate values from an independent source of higher accuracy for identical points. If those differences are normally distributed and average zero, 95 percent of any sufficiently large sample should be less than 1.96 times the RMSE. Therefore 9-centimeter RMSE can be referred to as "18-centimeter accuracy at the 95-percent confidence level." Following that convention, the vertical accuracy of any DEM is defined as 1.96 times the RMSE of linearly interpolated elevations in the DEM, as compared with known elevations from high-accuracy test points. DEMs should have a maximum RMSE as specified to meet its required vertical accuracy. The contractor must field verify the vertical accuracy of this DEM to ensure that the RMSE requirement is satisfied for all land cover classes that predominate within the floodplain being studied. result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: The ABGPS, IMU, and raw Optech LiDAR data are integrated into the Optech post processor software. The resultant file is in a LAS binary file format. The LAS file version 1.2 format can be easily transferred from one file format to another. It is a binary file format that maintains information specific to the LiDAR data (return#, intensity value, xyz, etc.). The resultant points are produced in the geodetic coordinates referenced to the NAD83 horizontal datum and NAVD88 2004.65 vertical datum. dateTime: DateTime: 2012-01-01T00:00:00 processStep: (LI_ProcessStep) description: The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary filters is applied as appropriate for the production of bare earth digital terrain models (dtms). Interactive editing methods are applied to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces. The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.2 format. The header file for each dataset is complete as define by the LAS 1.2 specification. The data was classified as follows: Class 1 = Unclassified. This class includes all non-ground classified points. Class 2 = Ground. Class 7 = Low Points. Class 9 = water. Class 12 = Overlap. dateTime: DateTime: 2012-01-01T00:00:00 processStep: (LI_ProcessStep) description: Conversion from Geodetic coordinates NAD83 into Louisiana state plane zone 1702 using NAD83 and conversion from ellipsoid heights (meters) into orthometric heights using NAVD88 (US Survey Foot). Files are orthogonally tiled based to a 1500m x 1500m extent, and labeled with a "Tile_ID" attribute. dateTime: DateTime: 2012-01-01T00:00:00 processStep: (LI_ProcessStep) description: Breaklines are manually collected using a first return surface model of the designated project area. After the completion of breaklines they are encoded into the LiDAR surface and used to hydro-flatten all significant water bodies. Once this has been accomplished Digital Elevation Models (DEM's) are created and processed to meet all mapping standards stated within contract. dateTime: DateTime: 2012-04-20T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received 525 files in .tif format. The bare earth raster files were at a 2 ft grid spacing. The data were in LA State Plane South, Zone 1702 (NAD83 NA11) coordinates and NAVD88 elevations in feet. OCM converted to cloud optimized geotiffs and ingested the data into the Digital Coast Data Access Viewer. dateTime: DateTime: 2020-01-21T00:00:00 processor: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor source: (LI_Source) description: Source Contribution: Lidar | Source Geospatial Form: remote-sensing image | Type of Source Media: digital tape media sourceCitation: (CI_Citation) title: LiDAR Acquisition for the Hurricane and Storm Damage Risk Reduction System date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: The Atlantic Group role: (CI_RoleCode) originator sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimePeriod: beginPosition: 2012-03-04 endPosition: 2012-03-25 | |
