The period of collection was between 3 October and 12 October 2006. This data set falls in Manatee County. The collection was performed by EarthData Aviation, using a Leica ALS-50 LiDAR system, including an inertial measuring unit (IMU) and a dual frequency GPS receiver. This project required six lifts of flight lines to be collected. The product generated consisted of LiDAR bare earth elevation models in LAS format. This data set is one component of a digital terrain model (DTM) for the Southwest Florida Water Management District's FY2005 Digital LiDAR Project (H048), encompassing approximately 291 square miles across Manatee County. The 2005 LiDAR dataset is comprised of 3-D mass points delivered in the LAS file format based on the District's 5,000' by 5,000' grid (325 cells). The other DTM component is 2-D and 3-D breakline features in the ESRI ArcGIS Personal Geodatabase format. In accordance with the 2005 SWFWMD Topographic Database Design, the following breakline 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 breaklines; 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. 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 mass point data display a vertical accuracy of at least 0.3-feet root mean square error (RMSE) in open unobscured areas. purpose: This project was designed to provide topographic information to the Southwest Florida Water Management District to support regulatory, land management and acquisition, planning, engineering and habitat restoration projects. credit: Southwest Florida Water Management District 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: Bathymetry/Topography keyword: LiDAR keyword: Bare Earth keyword: Terrain keyword: Model keyword: Elevation keyword: Surface type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: None date: descriptiveKeywords: (MD_Keywords) keyword: US keyword: Florida keyword: Southwest Florida keyword: Manatee County keyword: Upper Myakka 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.

EarthData Proprietary Software result: report: (DQ_ConceptualConsistency) measureDescription: Compliance with the accuracy standard was ensured by the collection of GPS ground control after the acquisition of aerial LiDAR and the establishment of a GPS base station at the Sarasota-Bradenton International Airport. The following checks were performed. 1. The ground control and airborne GPS data stream were validated through a fully analytical boresight adjustment. 2. The DTM (Digital Terrain Model) data were checked against the project control. 3. LiDAR elevation data was validated through an inspection of edge matching and visual inspection for quality (artifact removal). result: lineage: (LI_Lineage) processStep: (LE_ProcessStep) description: The airborne GPS data were processed and integrated with the IMU. The results were imported into the processing system for use in the LiDAR boresight. The raw LiDAR data was downloaded onto a production server. The ground control and airport GPS base station were used in conjunction with the processed ABGPS results for the LiDAR boresight. The properly formatted processing results were used for subsequent processing. dateTime: DateTime: 2006-11-15T00:00:00 processor: (CI_ResponsibleParty) individualName: Harold Rempel organisationName: EarthData International positionName: Director of Program Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 301-948-8550 facsimile: 301-963-2064 address: (CI_Address) deliveryPoint: 7320 Executive Way city: Frederick administrativeArea: Maryland postalCode: 21704 country: USA electronicMailAddress: hrempel@earthdata.com hoursOfService: Mon-Fri 9:00am to 5:00pm role: (CI_RoleCode) processor processStep: (LE_ProcessStep) description: EarthData has developed a unique method for processing LiDAR data to identify and remove elevation points falling on vegetation, buildings, and other aboveground structures. The algorithms for filtering data were utilized within EarthData's proprietary software and commercial software written by TerraSolid. This software suite of tools provides efficient processing for small to large-scale, projects and has been incorporated into ISO 9001 compliant production work flows. The following is a step-by-step breakdown of the process. 1. Using the LiDAR data set provided by EarthData Aviation, the technician performs calibrations on the data set. 2. The technician performed a visual inspection of the data to verify that the flight lines overlap correctly. The technician also verified that there were no voids, and that the data covered the project limits. The technician then selected a series of areas from the data set and inspected them where adjacent flight lines overlapped. These overlapping areas were merged and a process which utilizes 3-D Analyst and EarthData's proprietary software was run to detect and color code the differences in elevation values and profiles. The technician reviewed these plots and located the areas that contained systematic errors or distortions that were introduced by the LiDAR sensor. 3. Systematic distortions highlighted in step 2 were removed and the data was re-inspected. Corrections and adjustments can involve the application of angular deflection or compensation for curvature of the ground surface that can be introduced by crossing from one type of land cover to another. 4. The LiDAR data for each flight line was trimmed in batch for the removal of the overlap areas between flight lines. The data was checked against a control network to ensure that vertical requirements were maintained. Conversion to the client-specified datum and projections were then completed. The LiDAR flight line data sets were then segmented into adjoining tiles for batch processing and data management. 5. The initial batch-processing run removed 95% of points falling on vegetation. The algorithm also removed the points that fell on the edge of hard features such as structures, elevated roadways and bridges. 6. The operator interactively processed the data using LiDAR editing tools. During this final phase the operator generated a TIN based on a desired thematic layer to evaluate the automated classification performed in step 5. This allowed the operator to quickly re-classify points from one layer to another and recreate the TIN surface to see the effects of edits. Geo-referenced images were toggled on or off to aid the operator in identifying problem areas. The data was also examined with an automated profiling tool to aid the operator in the reclassification. 7. The point cloud data were delivered in LAS format. 10 - points in wetlands and ditches, 9 - points in water, 2 - ground points, and 1 - all other. dateTime: DateTime: 2007-01-15T00:00:00 processor: (CI_ResponsibleParty) individualName: Harold Rempel organisationName: EarthData International positionName: Director of Program Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 301-948-8550 facsimile: 301-963-2064 address: (CI_Address) deliveryPoint: 7320 Executive Way city: Frederick administrativeArea: Maryland postalCode: 21704 country: USA electronicMailAddress: hrempel@earthdata.com hoursOfService: Mon-Fri 9:00am to 5:00pm role: (CI_RoleCode) processor processStep: (LE_ProcessStep) description: The NOAA Coastal Services Center (CSC) received the files in LAS format.

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 Geoid 03. 3. The LAS data were sorted by latitude and the headers were updated. dateTime: DateTime: 2008-01-25T00:00:00 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 source: (LI_Source) description: Source Contribution: Aerial Acquisition.
