The data produced is satisfactory for the generation of both 1' and 2' contours. The average point spacing for all tiles is estimated to be 1 meter. purpose: LiDAR points depict the 'bald earth' within the project area. All points not specifically derived from the terrain are removed (tree canopy, buildings, etc.). As such, the file is useful for a variety of applications, such as aiding in contour generation and the production of orthophotos. status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) individualName: Kevin Willis organisationName: Lake County Board of County Commissioners, Department of Information Technology, GIS Division positionName: Interim GIS Director contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 352-343-9791 address: (CI_Address) deliveryPoint: 317 West Main Street, Historic Courthouse, 4th Floor city: Tavares administrativeArea: FL postalCode: 32778 country: U.S. electronicMailAddress: kwillis@lakecountyfl.gov role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded graphicOverview: (MD_BrowseGraphic) fileName: ftp://ftp.csc.noaa.gov/pub/crs/beachmap/qa_docs/fl/2007_LakeCounty_Florida/2007_LakeCounty_Florida.kmz fileDescription: This kmz file shows the extent of coverage for the 2007 Lake County, Florida lidar data set. fileType: kmz descriptiveKeywords: (MD_Keywords) keyword: Topography/Bathymetry keyword: Elevation keyword: Lidar keyword: LAS type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: None date: descriptiveKeywords: (MD_Keywords) keyword: Florida keyword: Lake County keyword: Tavares type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: None date: resourceConstraints: (MD_Constraints) useLimitation: These data depict the elevations at the time of the survey and are only accurate for that time.

Standard horizontal accuracy for LiDAR at this mapping scale is 1 meter (3.28'). result: report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Horizontal Positional Accuracy measureDescription: This value (in meters) is computed by comparing controls to an intensity based image derived from the classified LiDAR data and represents the RMSE of residuals on controls within the project area. result: (DQ_QuantitativeResult) valueUnit: BaseUnit: identifier: meters unitsSystem: value: Record: 1.0 report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy Report evaluationMethodDescription: Horizontal positional accuracy for LiDAR is dependent upon the quality of the GPS/INS solution, sensor calibration and ground conditions at the time of data capture. The vertical accuracy was tested with a result of a RMSE 0.062m (0.205'). result: report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy measureDescription: This value (in meters) is computed by comparing controls to the classified LiDAR ground surface and represents the RMSE of residuals on controls within the project area. result: (DQ_QuantitativeResult) valueUnit: BaseUnit: identifier: meters unitsSystem: value: Record: 0.062 report: (DQ_CompletenessCommission) evaluationMethodDescription: LiDAR data is collected within the project area, processed and verified against control. The bare earth surface will contain voids where insufficient energy was reflected from the surface to generate a valid return from the terrain. result: report: (DQ_ConceptualConsistency) measureDescription: Data was filtered using automated procedures followed by a manual review of the completed data set. result: lineage: (LI_Lineage) processStep: (LE_ProcessStep) description: At selected locations throughout the site, accurate GPS coordinates and elevations are surveyed and the points are marked with targets. dateTime: DateTime: 2007-01-01T00:00:00 processStep: (LE_ProcessStep) description: New LiDAR data is captured for the project area using a Leica ALS50 LiDAR instrument in conjunction with a POSAV Applanix GPS/INS system mounted within a Piper Navajo twin prop airplane. Base-station receivers are operated on the ground over known site points during the flyover to provide data necessary to reference the instrument position and orientation measurements to the terrain coordinate system. Altitude of flight was 6315' above mean sea level (AMSL). dateTime: DateTime: 2007-04-05T00:00:00 processStep: (LE_ProcessStep) description: The airborne GPS/INS data is processed, in both forward and reverse directions, together with the simultaneously recorded ground-based GPS base station data to determine the LiDAR sensor's angle and orientation in the terrain (project) coordinate datum during the survey. dateTime: DateTime: 2007-01-01T00:00:00 processStep: (LE_ProcessStep) description: LiDAR data is processed using the GPS/INS solution. Data is classified to produce a 'bald earth' surface and output to a LAS binary file format. dateTime: DateTime: 2007-01-01T00:00:00 processStep: (LE_ProcessStep) description: The NOAA Coastal Services Center (CSC) received topographic files in LAS format. The files contained lidar elevation and intensity measurements. The data were received in Florida State Plane East (Zone 0901) Coordinates and were vertically referenced to NAVD88 using the Geoid03 model. The vertical units of the data were survey feet. CSC performed the following processing for data storage and Digital Coast provisioning purposes: 1. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03. 2. The topographic las files were converted from Florida State Plane East (survey feet) to Geographic coordinates (decimal degrees). 3. The data were converted to LAZ format. dateTime: DateTime: 2013-01-01T00:00:00 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: 2013-04-25T00:00:00 processor: (CI_ResponsibleParty) individualName: Mike Sutherland organisationName: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 303-497-6120 facsimile: 303-497-6513 address: (CI_Address) deliveryPoint: NOAA/NESDIS/NGDC E/GC1 325 Broadway city: Boulder administrativeArea: CO postalCode: 80305-3328 country: USA electronicMailAddress: mike.sutherland@noaa.gov hoursOfService: 7:30am-5:00pm Mountain role: (CI_RoleCode) processor return to top metadataMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) annually dateOfNextUpdate: 2014-04-25 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 2013-04-25T14:11:13.643-06:00 |
