Data Report
Data report from the lidar acquisition contractor. This does not reflect processing done by NOAA OCM.
download
Aerial lidar collected over the Sycan Marsh in Lake and Klamath Counties, OR in 2020. The project area covers approximately 182 square miles. The project was flown with an Optech Galaxy PRIME lidar sensor at an approximate altitude of 5,249 feet above ground level (AGL). Lidar acquisition was planned with 60% side overlap and an aggregate point density of 8 points per square meter throughout the project area. The settings used for collection consisted of a pulse rate frequency (PRF) of 400 kHz, a scan frequency of 67.5 Hz, and a scan angle of +/- 20 degrees from the nadir position (full scan angle 40 degrees).
Meet the U.S. Forest Service need for monitoring and assessment.

Horizontal Positional Accuracy
Not tested.
Vertical Positional Accuracy
Using 120 validation points, the non-vegetated vertical accuracy (NVA) was 0.030 meters at the 95% confidence level.
Data were collected and processed by Aero-Graphics, Inc, for the U.S. Forest Service. The U.S. Forest Service transferred the data to NOAA for distribution on the Digital Coast.
LiDAR and imagery acquisition for the Sycan USFS R6 project was performed with an Optech Galaxy PRIME LiDAR sensor. The LiDAR sensor was placed in a customized mount to minimize error and increase accuracy. Aero-Graphics flew at an approximate altitude of 5,249 ft above ground level (AGL) and made appropriate adjustments to compensate for topographic relief over the projectâs over 71 flightlines. LiDAR acquisition was planned with 60% side overlap and an aggregate point density of 8 points per square meter throughout the project area. The settings used for collection consisted of a pulse rate frequency (PRF) of 400 kHz, a scan frequency of 67.5 Hz, and a scan angle of +/- 20 degrees from the nadir position (full scan angle 40 degrees).

The absolute sensor calibration was adjusted for the difference in roll, pitch, heading, and scale between the raw laser point cloud from the sensor and surveyed control points on the ground.
Differentially corrected the 1/5-second airborne GPS positions with ground base station; combined and refined the GPS positions with 1/200-second IMU (roll-pitch-yaw) data through development of a smoothed best estimate of trajectory (SBET).
SBET was combined with raw LiDAR range data and solved for real-world position for each laser point. Point cloud data was produced by flight strip in ASPRS v1.4 .LAS format and output in the local coordinate system.
Relative calibration was performed by correcting for roll, pitch, heading, and scale discrepancies between adjacent flightlines and the results were tested for accuracy.
Data was cut into project-specified tiles and grossly long and short returns were filtered out.
Classification algorithms were run on points in each tile, separating them into bare earth and unclassified points. Manually corrected areas that were not completely classified by the automated algorithms.
Data were received by NOAA Office for Coastal Management from the U.S. Forest Service in USFS region 6 Albers coordinates. Vertical coordinates were NAVD88 meters based on Geoid12b. The data were reprojected to geographic coordinates on the ellipsoid (EPSG:6319) for ingest into the NOAA Digital Coast system.
