The obtained RMSEh value is multiplied by a conversion factor of 1.7308 to yield the horizontal(radial) component at the 95% confidence level 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). Absolute accuracy was assessed using Non-Vegetated Vertical Accuracy (NVA) survey methods. Survey check points were evenly distributed as feasible throughout the project area. NVA compares known ground check point data that were withheld from the calibration and post-processing of the lidar point cloud to the triangulated surface generated by the ground classified lidar point cloud. NVA is a measure of the accuracy of lidar point data in open areas with level slope (less than 20°) where the lidar system has a high probability of measuring the ground surface and is evaluated at the 95% confidence interval (1.96*RMSE). Non-Vegetated Vertical Accuracy (NVA) was evaluated at the 95% confidence interval (1.96*RMSE). result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Horizontal Positional Accuracy evaluationMethodDescription: Based on a flying altitude of 400 meters, an IMU pitch/roll error of 0.002 decimal degrees, an IMU heading error of 0.003 decimal degrees, and a GNSS positional error of 0.005 meters, the RMSEh value for the Leica Chiroptera shallow green and NIR sensor data for the NOAA Chesapeake Topobathymetric Lidar project area is 0.029 meters, with an ACCr of 0.049 meters at the 95% confidence level. The RMSEh value for the Leica Hawkeye deep green sensor data in the NOAA Chesapeake Topobathymetric Lidar project area is 0.034 meters, with a ACCr of 0.059 meters at the 95% confidence level based on a flying altitude of 400 meters, an IMU pitch/roll error of 0.002 decimal degrees, an IMU heading error of 0.004 decimal degrees, and a GNSS positional error of 0.008 meters.

Project specifications require NVA meet 0.196 m accuracy at the 95% confidence interval. Bathymetric topography points were tested separately. In the project area, 258 survey checkpoints were used to assess the bathymetric topography accuracy. Project specifications require bathymetric topography shall meet a vertical RMSE of QL2b specified in the Draft National Coastal Mapping strategy 1.0 which is equivalent to 0.30 m RMSE at a depth of 1 m. Non-Vegetated Vertical Accuracy tested 0.056 m vertical accuracy at the 95% confidence level against the ground classified lidar point cloud in open terrain using 35 ground check points, based on RMSEz (0.028 m) x 1.9600. Bathymetric topography accuracy tested 0.094 m vertical accuracy at the 95% confidence level against the classified points cloud using 258 bathymetric check points, based on RMSEz (0.048 m) x 1.9600. These checkpoints usually occur in depths up to 1m.

All derived LAS data is referenced to: Horizontal Datum-NAD83(2011) epoch: 2010.00 Projection-UTM Zone 18N Horizontal Units-meters Vertical Datum-GRS80 Ellipsoid Vertical Units-meters NOAA provided NV5 with a project boundary for the NOAA Chesapeake Topobathymetric Lidar project. Using a 100 meter buffered boundary, NV5 created an airborne lidar acquisition plan. The collected lidar data were immediately processed in the field by NV5 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 using Waypoint Inertial Explorer 8.90, and the raw data were extracted into geo-referenced LAS files using Lidar Survey Studio 3.0 with pre-calculated scanner misalignment angles determined through a boresight protocol. These files were inspected for errors and then passed through an automated workflow, producing rasters to develop an initial assessment of bathymetric coverage. NV5 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 - 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. dateTime: DateTime: 2025-10-21T00:00:00 processor: (CI_ResponsibleParty) organisationName: Anchor: National Geodetic Survey role: (CI_RoleCode) processor processStep: (LI_ProcessStep) description: NV5 resolved kinematic corrections for the aircraft Global Navigation Satellite System (GNSS) data using static GPS data from Continuously Operating Reference Stations (CORS) utilizing the Online Positioning User Service (OPUS) for precise positioning. This data was used to correct the continuous on board measurements of the aircraft position recorded throughout the flight. Smoothed best estimate trajectories (SBET) were developed incorporating post-processed aircraft positionings with IMU and when present, gyrostabilized mount 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 Inertial Explorer v8.9 were used for final SBET creation. dateTime: DateTime: 2025-10-21T00:00:00 processor: (CI_ResponsibleParty) organisationName: Anchor: National Geodetic Survey role: (CI_RoleCode) processor processStep: (LI_ProcessStep) description: Following final SBET creation, NV5 used Leica's Lidar Survey Studio (LSS) to calculate laser point positioning by associating SBET positions to each laser point return time, scan angle, and intensity. LSS was used to derive a synthetic water surface to create a water surface model for refraction correction. 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 submerged green laser lidar data. All lidar data below water surface models were classified as water column to correct for refraction. Using raster-based QC methods, the output data is verified to ensure the refraction correction operated properly. dateTime: DateTime: 2025-10-21T00:00:00 processor: (CI_ResponsibleParty) organisationName: Anchor: National Geodetic Survey role: (CI_RoleCode) processor processStep: (LI_ProcessStep) description: Once all data was refracted by flight line, the lidar data was exported to LAS 1.4 files (point format 6) and delineated into 500 m x 500 m tiles. Data were then further calibrated using StripAlign and TerraMatch. NV5 used custom algorithms in TerraScan to classify the initial ground/bathymetric bottom points. Relative accuracy of overlapping swaths was compared and verified through the use of Delta-Z (DZ) orthos created using NV5's proprietary software Las Product Creator (LPC). Absolute vertical accuracy of the calibrated data was assessed using ground survey data. dateTime: DateTime: 2025-10-21T00:00:00 processor: (CI_ResponsibleParty) organisationName: Anchor: National Geodetic Survey role: (CI_RoleCode) processor processStep: (LI_ProcessStep) description: Post automated classification, NV5 performed manual reviews and editing to finalize all classification and improve the final topobathymetric surface.
