Horizontal Positional Accuracy
Horizontal positional accuracy for LiDAR is dependent upon the quality ofthe GPS/INS solution, sensor calibration and ground conditions at the time of data capture.The standard system results for horizontal accuracy are less than 1 meter.Not reported, assumed as 1.0 m. Laser horizontal errors are a function of flight altitudeabove ground (i.e., +/- 1/3000th AGL flight altitude). Relative errors for the position mustbe less than 1.5 cm horizontal and 2.0 cm vertical in order to be accepted.; Quantitative Value: 1.0 meters, Test that produced the value: See Lidar report.
Vertical Positional Accuracy
Upon the LiDAR data's arrival to the office, WSI processing staff initiates a suite ofautomated and manual techniques to process the data into the requested deliverables.Processing tasks include GPS control computations, smoothed best estimate trajectory(SBET) calculations, kinematic corrections, calculation of laser point position,calibration for optimal relative and absolute accuracy, and classification ofground and non-ground points.; Quantitative Value: 0.054 meters, Test that produced the value: Vertical absolute accuracy was primarily assessed from RTK ground check point (GCP)data collected on open, bare earth surfaces with level slope (less than 20 degrees).Fundamental Vertical Accuracy (FVA) reporting is designed to meet guidelinespresented in the National Standard for Spatial Data Accuracy (FGDC, 1998). FVAcompares known RTK ground survey check points to the triangulated ground surfacegenerated by the LiDAR points. FVA is a measure of the accuracy of LiDAR point datain open areas where the LiDAR system has a "very high probability" of measuring theground surface and is evaluated at the 95% confidence interval (1.96 sigma).Vertical accuracy was calculated at 2-sigma to 0.178 ft (5.4 cm).
Completeness Report
LiDAR data has been collected and processed for all areas within the project study area.
Conceptual Consistency
The accuracy of the LiDAR data collection can be described in terms of absolute accuracy (the consistency ofthe data with external data sources) and relative accuracy (the consistency of the dataset with itself). SeeAppendix A in the lidar report for further information on sources of error and operational measures used toimprove relative accuracy.
Planning.In preparation for data collection, WSI reviewed the project area using Google Earth,and flightlines were developed using a combination of specialized software. Carefulplanning by acquisition staff entailed adapting the pulse rate, flight altitude, scanangle, and ground speed to ensure complete coverage of the study area at thetarget point density of 11.43 points per square meter (ground points only were calculated at0.83 points per square meter). Efforts are taken to optimize flight paths by minimizingflight times while meeting all accuracy specifications.Factors such as satellite constellation availability and weather windows mustbe considered during the planning stage. Any weather hazards or conditions affectingthe flight were continuously monitored due to their potential impact on the dailysuccess of airborne and ground operations. In addition, a variety of logisticalconsiderations required review including private property access, potential airspace restrictions, and availability of company resources (both staff andequipment).Special care was taken to acquire the tidal flats at low tide wherepossible.
LiDAR Processing Steps:1. Resolve kinematic corrections for aircraft position data using kinematic aircraft GPSand static ground GPS data.Software - Waypoint GPS v.8.3 Trimble Business Center v.3.00 Geographic Calculator 20132. Develop a smoothed best estimate of trajectory (SBET) file that blends post-processedaircraft position with attitude data. Sensor head position and attitude are calculatedthroughout the survey. The SBET data are used extensively for laser point processing.Software - IPAS TC v.3.13. Calculate laser point position by associating SBET position to each laser point returntime, scan angle, intensity, etc. Create raw laser point cloud data for the entire surveyin *.las (ASPRS v. 1.2) format. Data are converted to orthometric elevations (NAVD88) byapplying a Geoid12 correction.Software - ALS Post Processing Software v.2.744. Import raw laser points into manageable blocks (less than 500 MB) to perform manualrelative accuracy calibration and filter erroneous points. Ground points are thenclassified for individual flight lines (to be used for relative accuracy testingand calibration).Software - TerraScan v.13.0085. Using ground classified points per each flight line, the relative accuracy is tested.Automated line-to-line calibrations are then performed for system attitude parameters(pitch, roll, heading), mirror flex (scale) and GPS/IMU drift.Calibrations are calculated on ground classified points from paired flight lines andresults are applied to all points in a flight line. Every flight line is used forrelative accuracy calibration.Software - TerraMatch v.13.0026. Classify resulting data to ground and other client designated ASPRSclassifications (Table 7). Assess statistical absolute accuracy via direct comparisonsof ground classified points to ground RTK survey data.Software - TerraScan v.13.008 TerraModeler v.13.0027. Generate bare earth models as triangulated surfaces. Highest hit models were createdas a surface expression of all classified points (excluding the noise and withheldclasses). All surface models were exported as ESRI grids at a 3-foot pixel resolution.Software - TerraScan v.13.008 ArcMap v. 10.1 TerraModeler v.13.002
The NOAA Office for Coastal Management (OCM) downloaded topographic files in LAZ format from PSLC's website.The files contained lidar easting, northing, elevation, intensity, return number, class, scan angleand GPS time measurements. Entiat data were received in Washington State Plane North, 4601 (feet) andreferenced to NAVD88 (feet).OCM performed the following processing for data storage and Digital Coast provisioning purposes:1. The All-Return LAZ files were cleared of variable lengths records.2. The All-Return LAZ files were converted from a Projected Coordinate System (State Plane 4601)to a Geographic Coordinate system (NAD83).3. The All-Return LAZ files were converted from NAVD88 to ellipsoidal heights using Geoid03.

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.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
