The 100 meter buffered project area consists of approximately 2,120,060 acres encompassing the Florida Panhandle and extending south to New Port Richey, Florida, and was collected between November 2019 - July 2020 using a Leica Chiroptera 4X system. The dataset includes topobathymetric data in a LAS format 1.4, point data record format 6. This data set also includes Lidar intensity values, number of returns, return number, time, and scan angle. LAS files were compiled into a total of 44,926 500 m x 500 m tiles. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: This lidar data are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping (IOCM) initiative to increase support for multiple uses of the data. It is not intended for mapping, charting, or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne lidar. credit: We request that you credit the National Oceanic and Atmospheric Administration (NOAA) when you use these data in a report, publication, or presentation., Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Geodetic Survey (NGS), Remote Sensing Division Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Office for Coastal Management (OCM) The custom download may be cited as National Oceanic and Atmospheric Administration (NOAA) Digital Coast Data Access Viewer.

The obtained RMSEr value is multiplied by a conversion factor of 1.7308 to yield the horizontal component of the National Standards for Spatial Data Accuracy (NSSDA) reporting standard where a theoretical point will fall within the obtained radius 95 percent of the time (ACCr). Based on a flying altitude of 400 meters, an IMU error of 0.004 decimal degrees, and a GNSS positional error of 0.008 meters, the RMSEr value for the Delivery 1 area is 0.05 meters, with a ACCr of 0.09 meters at the 95% confidence level. The project specification requires horizontal positions to be accurate to 1.0m(RMSE). Based on a flying altitude of 400 meters, an IMU error of 0.007 decimal degrees, and a GNSS positional error of 0.027 meters, the RMSEr value for the Delivery 2 area is 0.09 meters, with a ACCr of 0.16 meters at the 95% confidence level.

All derived LAS data was referenced to: Horizontal Datum-NAD83(2011) epoch: 2010.00 Projection-UTM Zone 16N and UTM17N Horizontal Units-meters Vertical Datum-GRS80 Ellipsoid Vertical Units-meters The collected Lidar data were immediately processed in the field by QSI to a level that will allow QA\QC measures to determine if the sensor is functioning properly and assess the coverage of submerged topography. An initial SBET was created in POSPAC MMS 8.3 SP3 and loaded into RiProcess which applies pre-calibrated angular misalignment corrections of scanner position to extract the raw point cloud into geo-referenced LAS files. These files were inspected for sensor malfunctions and then passed through automated raster generation using LAStools to develop an initial assessment of bathymetric coverage. QSI reviewed all acquired flight lines to ensure complete coverage and positional accuracy of the laser points. These rasters were also used to create an initial product in Quick Look Coverage Maps. These Quick Look files are not fully processed data or final products but provide rapid assessment of approximate coverage and depth penetration. QSI resolved kinematic corrections for aircraft position data using aircraft GNSS and Applanix's proprietary PP-RTX solution. When PP-RTX was not used QSI conducted static Global Navigation Satellite System (GNSS) ground surveys (1 Hz recording frequency) using base stations over known monument locations during flights. After the airborne survey, static GPS data were triangulated with nearby Continuously Operating Reference Stations (CORS) using the Online Positioning User Service (OPUS) for precise positioning. Multiple independent sessions over the same base station were performed to confirm antenna height measurements and to refine position accuracy. This data was used to correct the continuous on board measurements of the aircraft position recorded throughout the flight. A final smoothed best estimate trajectory (SBET) was developed that blends post-processed aircraft position with attitude data. Using the SBETs, sensor head position and attitude were then calculated throughout the survey. Trimble Business Center v.3.90, Blue Marble Geographic Calculator 2019, and PosPac MMS 8.3 SP3 were used for these processes. Following final SBET creation, QSI used Leica Lidar Survey Studio (LSS) to calculate laser point positioning by associating SBET positions to each laser point return time, scan angle, and intensity. Leica LSS was used to derive a synthetic water surface to create a water surface model. All LiDAR data below water surface models were classified as water column to correct for refraction. Light travels at different speeds in air versus water and its direction of travel or angle is changed or refracted when entering the water column. The refraction tool corrects for this difference by adjusting the depth (distance traveled) and horizontal positioning (change of angle/direction) of the LiDAR data. Using raster-based QC methods, the output data is verified to ensure the refraction tool functioned properly. Dewberry performed the calibration of the NOAA Michael Delivery 1 Lidar dataset in addition to the point cloud classification in order to create the final topobathymetric lidar deliverables which were subsequently reviewed by QSI. dateTime: DateTime: 2020-06-26T00:00:00 processStep: (LI_ProcessStep) description: Relative accuracy of the green swaths compared to overlapping and adjacent green swaths as well as the relative accuracy of green swaths compared to overlapping and adjacent NIR swaths was verified through the use of Delta-Z (DZ) orthos. Dewberry created DZ rasters using proprietary processing tools. The intraswath or within a swath accuracy were verified using GIS software. Profiles of elevated planar features, such as roofs, were used to verify horizontal alignment between overlapping swaths. All lidar data was peer-reviewed. QAQC also included creating void polygons for use during review. All necessary edits were applied to the dataset. NV5 Geospatial's proprietary software, LAS Monkey, was used to update LAS header information, including all projection and coordinate reference system information. The final lidar data is in LAS format 1.4 and point data record format 6. The contractor delivered classification scheme is as follows: 1- Unclassified 2- Ground 7- Noise 40- Bathymetric bottom or submerged topography 41- Water surface 43- Submerged object 45- water column 46- overlap bathy bottom - temporally different from a separate lift 71- unclassified associated with areas of overlap bathy bottom/temporal bathymetric differences 72- ground associated with areas of overlap bathy bottom/temporal bathymetric differences 81- water surface associated with areas of overlap bathy bottom/temporal bathymetric differences 85- water column associated with areas of overlap bathy bottom/temporal bathymetric differences 1Overlap- Edge clip 1Withheld- Green laser returns in topo only areas 42Synthetic- derived water surface All data was then verified by an Independent QC department. The independent QC was performed by separate analysts who did not perform manual classification or editing. The independent QC involved quantitative and qualitative reviews. processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received files in laz format. The files contained lidar elevation and intensity measurements. The data were in UTM Zone 16 & UTM 17 coordinates and ellipsoid elevations in meters. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Converted from UTM Zones to geographic coordinates 2. Sorted by gps time. 3. Moved data from class 71 to class 1, and moved points classed 46, 72. 81 & 85 to class 22. The final classification scheme is as follows: 1- Unclassified 2- Ground 7- Noise 22- Temporal Exclusion 40- Bathymetric bottom or submerged topography 41- Water surface 42- Synthetic - Derived Water surface 43- Submerged object 45- water column 46- overlap bathy bottom - temporally different from a separate lift 1Overlap- Edge clip 1Withheld- Green laser returns in topo only areas processor: (CI_ResponsibleParty) organisationName: Office for Coastal Management role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: Processed Lidar date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: NV5 role: (CI_RoleCode) originator processStep: (LI_ProcessStep) description: The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
