Range Offset A4: -0.011
Range Offset B1: 0.000
Range Offset B2: 0.002

Have computed scanner offsets and most (all) flightlines are way off the scan correct value given by leica (-10340) averaging them all has resulted in 16640 as a potential value.
There is however one flightline that carries a value of -172016 which is considerably above the other values given, removing this from the averaging results in a value of 10310. I will try to run the calibration using both values to see differences.

Pitch roll and heading values found as:
roll | -0.003918414 |
pitch | 0.00113716 |
heading | 0.00056484 |
The roll error is an average of the best values for high and low alt lines being:
high | −0.003991482 |
low | −0.003845345 |

Range calibration completed using averaged roll error.
Lascontrol gave a result of -1.58854 which was used with RangeCardCal to get the following values:
A1 | -1.58854 | B1 | -1.589 |
A2 | -1.582 | B2 | -1.587 |
A3 | -1.548 | B3 | -1.591 |
A4 | -1.599 | B4 | -1.569 |
Lascontrol gave an average dz of 0.0164776 with std dev of 0.0206099 on low altitude
0.0683441 with std dev of 0.0197977 on mid altitude and
0.0525533 with std dev of 0.0377199 on high altitude.

The full wave form files were not present so this has not been calibrated.

Beginning hyperspectral boresight.

Second attempt at LiDAR calibration, based on the results of the first one but trying to convert to using torsion and pitch error slope (pes) rather than forward laser angle (FLA). Fiddled with boresight parameters and range correction after changing over to torsion and pes.

I've moved the original processing for the hyperspectral boresight to processing/original_hyperspectral, will move back when dap is finished learning some hyperspectral processing.

Moved hyperspectral processing back.
Nav data processed, good solution achieved
