Quantum Spatial collected the OLC Wallowa LiDAR data between 07/04/15 and 07/15/15. The survey used a Leica ALS70 laser system mounted in a Cessna Caravan. Data was collected using multi pulse flight plan. Near nadir scan angles were used to increase penetration of vegetation to ground surfaces. Ground level GPS and aircraft IMU were collected during the flight.
Leica ALS70 Instrument Parameters:
Beam diameter: 32 cm,
Pulse rate: 198 kHz,
Maximum returns: 4,
Speed: 110 knots,
Overlap: 60 %,
Laser power: 71 %,
Field of view (FOV): 28°,
Beam wavelength: 1064 nm,
Frequency of GPS sampling: 2 Hz,
Frequency of IMU sampling: 200 Hz,
Swath width: 750 m,
AGL: 1400 m,
Average pulse density: 8ppms2015-07-15T00:00:00For the real time kinetic (RTK) check point data collection, a Trimble R7 base unit was positioned at a nearby monument to broadcast a kinematic correction to a roving Trimble R8 and R10 receiver. All RTK measurements were made during periods with a Position Dilution of Precision (PDOP) of 3.0 or less with at least six satellites in view of the stationary and roving receivers. When collecting RTK data, the rover would record data while stationary for five seconds, then calculate the pseudorange position using at least three one-second epochs. Relative error for the RTK check point must be less than 1.5 cm horizontal and 2.0 cm vertical in order to be accepted. 293 land class points were collected and utilized in the assesment of the vertical accuracy of the LiDAR data point cloud.The distribution of land class points depended on ground access constraints and may not be equitably distributed throughout the study area.
