The dataset for Wakulla County, Florida satisfies the criteria: Countywide Lidar dataset tested 16.8 cm (0.55 ft) vertical accuracy at 95% confidence level in open terrain, based on open terrain RMSEz (8.5 cm (0.28 ft)) x 1.9600. Countywide Lidar dataset tested 0.20 cm (.64 ft) vertical accuracy at 95% confidence level in all land cover categories combined, based on consolidated RMSEz (10.1 cm (.33 ft)) x 1.9600. result: (DQ_QuantitativeResult) valueUnit: BaseUnit: identifier: meters unitsSystem: value: Record: 0.168 report: (DQ_CompletenessCommission) evaluationMethodDescription: A visual qualitative assessment was performed to ensure the data completeness against the intensity images derived from Lidar points. No void or missing data. result: report: (DQ_ConceptualConsistency) measureDescription: Data covers the tile scheme provided for the county. result: lineage: (LI_Lineage) processStep: (LE_ProcessStep) description: The ABGPS, IMU, and raw Optech 3100ea Lidar scans are integrated using Optech Incorporated's DASHMap, version 1.1 software, Terrascan software and Microstation software. The resultant file is in a LAS binary file format . The LAS file version 1.1 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 referenced to the NAD83 horizontal datum and GRS80 vertical datum. The date and time for each flight line can be determined using the Julian date and time. The Julian date is a continuous count of days and fractions since noon Universal Time on January 1, 4713 BCE on the Julian Calendar. dateTime: DateTime: 2008-01-01T00:00:00 processor: (CI_ResponsibleParty) organisationName: Terrapoint USA positionName: Lidar Manager contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 1-877-999-7687 facsimile: 1-281-296-0869 address: (CI_Address) deliveryPoint: 251216 Grogan's Park Drive city: The Woodlands administrativeArea: Texas postalCode: 77380 country: USA electronicMailAddress: peggy.cobb@terrapoint.com hoursOfService: Monday to Friday, 8 - 5, CST role: (CI_RoleCode) processor processStep: (LE_ProcessStep) description: The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary filters are 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 1.1 format. The header file for each dataset is complete as define by the LAS 1.1 specification. In addition the following fields are included (Precision reported in brackets): Class (Integer); GPS Week Time (0.0001 seconds); Easting (0.01 meter); Northing (0.01 meter); Elevation (0.01 meter); Echo Number (Integer 1 to 4); Echo (Integer 1 to 4); Intensity (8 Bit Integer); Flightline (Integer); Scan Angle (Integer Degree). The LAS files do not include overlap. The data was classified as follows: Class 1 = Unclassified. This class includes vegetation, buildings, noise etc. Class 2 = Ground Class 7= Noise Class 9 = Water dateTime: DateTime: 2008-01-01T00:00:00 processor: (CI_ResponsibleParty) organisationName: Terrapoint USA positionName: Lidar Manager contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 1-877-999-7687 facsimile: 1-281-296-0869 address: (CI_Address) deliveryPoint: 251216 Grogan's Park Drive city: The Woodlands administrativeArea: Texas postalCode: 77380 country: USA electronicMailAddress: peggy.cobb@terrapoint.com hoursOfService: Monday to Friday, 8 - 5, CST role: (CI_RoleCode) processor processStep: (LE_ProcessStep) description: The NOAA Coastal Services Center (CSC) received the files in las format. The files contained Lidar elevation and intensity measurements. The data were in projected in Florida State Plane Coordinates (North Zone, NAD83/HARN), and referenced to the orthometric datum of NAVD88 utilizing Geoid 03. CSC performed the following processing to the data to make it available within the Digital Coast: 1. The data were converted from State Plane Coordinates (NAD83/HARN) coordinates to geographic coordinates (NAD83). 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03. 3. The LAS data were sorted by latitude and the headers were updated. dateTime: DateTime: 2010-12-07T00:00:00 processor: (CI_ResponsibleParty) organisationName: DOC/NOAA/NOS/CSC > Coastal Services Center, National Ocean Service, National Oceanic and Atmospheric Administration, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 843-740-1200 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave. city: Charleston administrativeArea: SC postalCode: 29405-2413 electronicMailAddress: csc.info@noaa.gov role: (CI_RoleCode) processor processStep: (LE_ProcessStep) description: The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format. The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights. dateTime: DateTime: 2011-09-09T00:00:00 processor: (CI_ResponsibleParty) individualName: Pamela Grothe organisationName: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) contactInstructions: Contact Data Center role: (CI_RoleCode) processor source: (LI_Source) description: Source Contribution: Lidar dataset was used to create intensity stereopairs for 3D breakline compilation and for contour generation.Source Type: online sourceCitation: (CI_Citation) title: Lidar date: (CI_Date) date: 2007-01-01 dateType: (CI_DateTypeCode) publication citedResponsibleParty: (CI_ResponsibleParty) organisationName: Terrapoint USA role: (CI_RoleCode) originator presentationForm: (CI_PresentationFormCode) mapDigital otherCitationDetails: Lidar Survey of Wakulla County, Florida, conducted in 2007 in support of the Florida Division of Emergency Management (FDEM). sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimePeriod: beginPosition: 2007-05-04 endPosition: 2007-08-16 return to top metadataMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) annually dateOfNextUpdate: 2014-06-07 maintenanceNote: This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2013-01-04 version of the FGDC RSE to ISO 19115-2 for LiDAR transform. maintenanceNote: Translated from FGDC 2013-06-07T12:41:43.78-06:00 maintenanceNote: Last Metadata Review Date: 2011-11-19 |
