Four sites were flown, covering a total of 177 acres. A fixed-wing PH Lancaster (revision 5) platform was used, carrying a Velodyne Puck VLP-16 based lidar system. The system provides 2 returns (strongest and last) with a pulse rate of 300 kHz using a 903 nm wavelength laser. Flights were conducted from May 9-11, 2017 and were flown at 50 meters above ground level. Specifications for the collection included 30 pulses per square meter and 0.10 meter RMSE vertical accuracy in non-vegetated areas. The average first return density was over 105 points per square meter with an average ground classified density of over 3 points per square meter. Deliverables included the lidar point cloud in LAS/LAZ format. Data were delivered in UTM zone 16 NAD83(2011) horizontally and NAVD88 (Geoid12b) meters vertically. Lidar point clouds were projected back to geographic coordinates for storage in the Digital Coast Data Access Viewer and the vertical datum was converted to the ellipsoid.

The statistical model compares known ground survey points (GSPs) to the closest laser point. Vertical accuracy statistical analysis uses ground survey points in open areas where the LiDAR system has a "very high probability" that the sensor will measure the ground surface and is evaluated at the 95th percentile. For the Grand Bay NERR area, NOAA and Grand Bay NERR collected 106 points in non-vegetated areas for comparison. Analysis indicated a vertical RMSE of 0.072 meters. Non-parametric examination of the errors showed a 95% confidence level of 0.145 meters. ; Quantitative Value: 0.072 meters, Test that produced the value: Tested to meet FVA at a 95 percent confidence level in meters. result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: LiDAR data has been collected and processed for all areas within the project study area. result: (missing) report: (DQ_ConceptualConsistency) nameOfMeasure: Conceptual Consistency evaluationMethodDescription: Upon receipt from vendor (Quantum Spatial), all LiDAR data was independently reviewed by staff from the NOAA Office for Coastal Management (OCM) to ensure project specifications were met. All data were inventoried for completeness and data were checked for quality, which included examining LiDAR data for errors associated with internal data consistency, model quality, and accuracy. result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: The LiDAR survey occurred between May 9, 2017 and May 11, 2017 using a Velodyne Puck VLP-16 laser system mounted in PrecisionHawk's Lancaster Rev 5 Dual-Frequency GPS UAS and flown by PrecisionHawk pilots. Upon completion of data acquisition, Precision Hawk processed SBETs and raw point data into geolocated swaths. Processing tasks included GPS control computations, smoothed best estimate trajectory (SBET) calculations, kinematic corrections, and calculation of laser point position. Ground control data was collected by Precision Hawk to be used in the post-processing and calibration of the LIDAR flights. Following calibration, QSI initiated a suite of automated and manual techniques to classify the LiDAR points and create the requested deliverables. Processing methodologies were tailored for the landscape. Classifications were as follows: Unclassified (class 1) - Laser returns that are not included in the ground class or other vegetation classes, retained in order to avoid false vegetation classing within roads or other bare ground surfaces. Ground (class 2) - Laser returns that are determined to be ground using automated and manual cleaning algorithms. Low Noise (class 7) - Laser returns that are determined to be artificial points below the ground surface. Water (class 9) - Laser returns that are determined to be water using manual cleaning techniques. Near Ground Noise (class 14) - Laser returns that are determined to be artificial points between 0 and 20 meters above the ground surface. High Noise (class 18) - Laser returns that are determined to be artificial points, equal to or greater than 20 meters above the ground surface. dateTime: DateTime: 2017-01-01T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received the files in laz format. The files contained Lidar elevation and intensity measurements. The data were in UTM zone 16 (NAD83 2011 Epoch 2010.0) and NAVD88 (Geoid12b) vertical meters. OCM performed the following processing to the data to make it available within the Digital Coast: 1. The data were converted from UTM to geographic coordinates. 2. The data were converted from NAVD88 (orthometric) heights to NAD83(2011) ellipsoid heights using Geoid12b grids. The data was received without a metadata record. This record was produced based on the data quality report. dateTime: DateTime: 2017-09-01T00:00:00 processor: (CI_ResponsibleParty) organisationName: Office for Coastal Management role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: Processed Lidar Data date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: Quantum Spatial, Inc 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.
