The 2006 LiDAR dataset is comprised of 3-D masspoints delivered in the LAS file format based on the District's 5,000' by 5,000' grid (1,356 cells). The other DTM component is 2-D and 3-D breakline features in the ESRI ArcGIS Personal Geodatabase format. In accordance with the 2006 SWFWMD Topographic Database Design, the following breakline features are contained within the database: closed water bodies (lakes, reservoirs, etc) as 3-D polygons; linear hydrographic features (streams, canals, swales, embankments, etc) as 3-D breaklines; coastal shorelines as 3-D linear features; edge of pavement road features as 3-D breakines; soft features (ridges, valleys, etc.) as 3-D breaklines; obscured vegetation polygons as 2-D polygons; overpasses and bridges as 3-D breaklines; 1-foot contours for visualization purposes; and island features as 3-D polygons. This data falls in Citrus and Sumter Counties. Intensity values, or the measure of reflectance of the laser are also captured. Breakline features were captured to develop a hydrologically correct DTM. Contours (1-foot) were generated from the DTM that meet the National Map Accuracy Standards for 2-foot contours (FEMA specifications). Bare earth LiDAR masspoint data display a vertical accuracy of at least 0.3-feet root mean square error (RMSE) in open unobscured areas purpose: The DTM was developed to support the DISTRICT's regulatory, land management and acquisition, planning, engineering, and habitat restoration projects status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) individualName: Mapping and GIS Section organisationName: Southwest Florida Water Management District contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 352.796.7211 facsimile: 352.540.6018 address: (CI_Address) deliveryPoint: 2379 Broad Street city: Brooksville administrativeArea: Florida postalCode: 34604 country: USA hoursOfService: 8:00 am - 5:00 pm role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded descriptiveKeywords: (MD_Keywords) keyword: Topography/Bathymetry keyword: laser keyword: Terrain keyword: Model keyword: Elevation keyword: Surface keyword: LiDAR type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: none date: descriptiveKeywords: (MD_Keywords) keyword: United States keyword: Florida keyword: Citrus County keyword: Sumter County 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.

The DTM is intended to support 2-foot contours, and the vertical accuracy of ground points in unobscured areas is 0.3-feet RMSE. result: lineage: (LI_Lineage) processStep: (LE_ProcessStep) description: The LiDAR data was acquired using a Leica ALS50 from an altitude of 2,400' above ground level to provide an nominal ground sample distance of 2.4-feet. The scanner field of view was 28-degrees, and the scan rate was 46-hertz. First and last return data was collected along with the signal return intensity. A total of 278 flights of LiDAR data were acquired. Flight lines were flown with a 30% sidelap, providing a line-to-line swath width of 957-feet. Thirty (30) Two redundant airborne GPS bases stations were utilized during the data acquisition with maximum line-of-sight distance between the base station and aircraft of 20-km. The LiDAR data was reduced using Grafnav (Waypoint Consulting) for GPS post-processing, PosProc (Applanix Crop) for IMU processing, ALS50 Post Processor (LH Systems) to initial LiDAR processing, TerraScan (Terrasolid) for initial point classification, and proprietary Woolpert developed software for refining the point classification and QC. The LAS files contain 5 classifications: 1 = unclassified; 2 = ground; 9 = water; and 10 = photogrammetric mass points and 11=swamp/wetland points. The class 1 consists of all points not on the ground. Class 2 consists of bare earth points. Class 9 points are those points falling within lake/pond polygons. Class 10 consists of supplementary mass points that were photogrametrically compiled on points features suchs as peaks or pits, and they were created to maintain the accuracy of the DTM. Class 11 consists of points within swamps and/or wetlands polygons classified as ground.

The files contained Lidar elevation measurements. The data was in Florida State Plane Projection and NAVD88 vertical datum. CSC performed the following processing to the data to make it available within the LDART Retrieval Tool (LDART): 1. The data were converted from Florida State Plane West coordinates to geographic coordinates. 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid03. 3. The LAS data were sorted by latitude and the headers were updated. dateTime: DateTime: 2008-01-01T00:00:00 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: 2009-07-14T00:00:00 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 return to top metadataMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) annually dateOfNextUpdate: 2014-06-11 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 2013-06-11T09:44:04.132-06:00 maintenanceNote: Last Metadata Review Date: 2011-11-19 |
