Data cover the entire area specified for this project.
These raw LAS data files include all data points collected. No points have been removed or excluded. A visual qualitative assessment was performed to ensure data completeness. No void areas or missing data exist. The raw point cloud is of good quality and data passes Fundamental Vertical Accuracy specifications.
The specifications require that only Nonvegetated Vertical Accuracy (NVA) can be computed for raw lidar point cloud swath files. The vertical accuracy was tested with 37 independent surveys located in open terrain. The survey check points were distributed throughout the project. Specifications for this project require that the NVA be 18.2 cm or better AccuracyZ at 95 percent confidence level.
The RMSEz was computed to be 0.092 meters. AccuracyZ has been compiled to meet 9.25 cm Fundamental Vertical Accuracy at 95 Percent confidence level using RMSE(z) x 1.9600 as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASRPS Guidelines.
0.014 meters AccuracyZ at 95 percent Confidence Interval
This data source was used (along with the airborne GPS/IMU Data) to georeferencing of the lidar point cloud data.

Airborne GPS and IMU data were merged to develop a Smoothed Best Estimate (SBET) of the lidar system trajectory for each lift. Lidar ranging data were initially calibrated using previous best parameters for this instrument and aircraft. Using Optech\s LiDAR Mapping Suite 4.1 software, relative calibration was evaluated using advanced plane-matching analysis and parameter corrections were derived. This relative calibration was repeated iteratively until residual errors between overlapping swaths, across all project lifts, was reduced to 3 cm or less. Data were then block adjusted to match surveyed calibration control.

Lidar Post-Processing: After generation of the calibrated point cloud data in LAS format from Leica's ALS Post-Processor software, the data is imported into the TerraSolid software suite (running under Bentley\’s MicroStation) for matching and classification. Upon import, the data is divided into tiles for the purpose of creating more manageable data. Once imported to TerraSolid, blocks of data containing overlapping flight lines are selected. The data in these blocks is analyzed by TerraMatch and adjustments to the roll, pitch, heading, and scale that minimize any data misalignment between the flight lines are computed. These adjustments are then applied to the entire mission’s worth of data. Data across the mission is then manually reviewed to ensure proper alignment between flightlines has been achieved. This process is then repeated for each mission; once complete, intra-sortie alignment is verified.
