LiDAR data will support hydrologic modeling activities associated with the FederalEmergency Management Agency (FEMA), and in the creation of Digital Flood Insurance Rate Maps(DFIRM). The LiDAR data will support the creation of Federal Emergency Management AgencyFlood Insurance Rate Maps (FEMA FIRM) and an integrated ground and surface water model for Pasco County. The data were classified into 7 classifications; (1) unclassified, (2) ground, (6) buildings, (9) water, (11) wetlands, (23) bridges, (30) ground within 10 ft of a breakline, and (31) overlap. Cooner & Associates performed the vertical accuracy and horizontal accuracy QA/QC analysis. The purpose of this project is to provide professional surveying and LiDAR services to the SWFWMD for the creation of a high-resolution digital elevation model for a 72.81 Square mile area of interest (AOI) in Pasco County, Florida(based on a 5,000-ft by 5,000-ft tiling scheme). The project area is shown in the graphic above and required 106 flight lines flown at 5,500' ASL. completed NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information pointOfContact NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information custodian asNeeded https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/4697/supplemental/fl2011_swfwmd_pasco_m4697.kmz This graphic shows the coverage of the 2011 Pasco County (FL) lidar collection. kmz swfwmd theme 2011 February January temporal Lidar - partner (no harvest) project InPort otherRestrictions Cite As: OCM Partners, [Date of Access]: 2011 SWFWMD Topographic Lidar: Pasco County [Data Date Range], https://www.fisheries.noaa.gov/inport/item/49700.

Horizontal Positional Accuracy The scope stated that horizontal accuracies for the LiDAR data sets should meet or exceed a verified horizontal accuracy of 1.158 meters at the 95% confidence interval (0.671 meters RMSE) as specified in the FGDC Geospatial Positioning Accuracy Standards, Part 3: National Standard for Spatial Data Accuracy (NSSDA). A minimum of thirty independent checkpoints within the project area were used for verification.; Quantitative Value: 1.158 meters, Test that produced the value: +/- 115.8 cm, 2 sigma Vertical Positional Accuracy The scope also defined the Fundamental Vertical Accuracy (FVA) at meeting or exceeding 0.183 meters at 95% confidence level (0.0914 meter RMSE) in open well defined terrain. A minimum of thirty check points for each land cover category will be checked (Urban; Bare Ground/Short Grass; and Brush). Supplemental Vertical Accuracy (SVA) shall meet or exceed 0.363 meters (0.192 meter RMSE) with a minimum of thirty check points in the following land cover types, (Wet Prairies and Pine Flatwoods). Finally the Consolidated Vertical Accuracy (CVA) shall not exceed the above accuracy requirements when all the values are tested as a combined QC check.; Quantitative Value: 0.061 meters, Test that produced the value: 6.1 cm RMSEz Completeness Report This data set covers the spatial extent of topographic lidar data obtained during this survey. Conceptual Consistency Data covers the tile scheme provided for the county and was verified for correct topology. Hydro connectivity, monotonicity and vertical consistency of the breaklines was validated. All flights for the project were accomplished with two customized single-engine Cessna 206s' which provide an ideal, stable aerial base for LiDAR acquisition. This platform has relatively fast cruise speeds that are beneficial for project mobilization I demobilization while maintaining relatively slow stall speeds which can prove ideal for collection of a high-density, consistent data posting. Photo Science utilized two Optech Gemini scanners on this project (Serial Numbers 246 and 247). The systems are capable of collecting data at a maximum frequency of 167kHz, which affords elevation data collection of up to 167,000 points per second. The system utilizes a Multi-Pulse in the Air Option (MPIA). This sensor is also equipped with the ability to measure up to 4 returns per outgoing pulse from the laser and these come in the form of 151, 2nd, 3rd, and last returns. The intensity of the first three returns is also captured during the aerial acquisition. Optech DASHmap software was used in the post-processing of the airborne GPS and inertial data. This software suite includes the Applanix POSPac and Waypoint's GrafNav solutions. POSPac provides the smoothed best estimate of trajectory (SBET) that is necessary for Optech's post processor to develop the point cloud from the Lidar missions. The point cloud was created using Optech's Post Processor software. GeoCue's TerraScan was used in the creation of files needed in downstream processing, as well as in the tiling of the dataset into more manageable file sizes. The TerraScan and TerraModeler software packages are then used for the automated data classification, manual cleanup, and bare earth generation from this data. Project specific macros were used to classify the ground and to remove the side overlap between parallel flight lines. All data were manually reviewed and any remaining artifacts removed using TerraScan and TerraModeler. QT Modeler was used as a final check of the bare earth dataset. GeoCue was then used to create the deliverable LAS 1.2 files for both the All Point Cloud Data and the Bare Earth. In-house software was then used to perform final statistical analysis of the classes in the LAS files. 2009-01-01T00:00:00 The NOAA Office for Coastal Management (OCM) received the topographic lidar files in LAS format from SWFWMD. The files contained lidar easting, northing, elevation, intensity, return number, etc. The data was received in Florida State Plane West 0902 (US ft) and NAVD88 (US ft). OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The files were reviewed and erroneous elevations were removed. 2. Files were converted to geographic coordinates and vertically transformed to ellipsoid heights. 2014-09-24T00:00:00
