Navigation Processing
Navigation processing complete. Error about missing trajectory files in IPAS TC (had same error for most of Malaysia data), good result obtained in IPAS Pro using standard settings.

Fenix Boresight
Found final SCTs:
5 | 0.95 |
6 | -0.05 |
9 | 0.97 |
10 | 0.97 |
13 | 0.97 |
14 | 0.96 |
Found boresight values (using existing lever arms as no new plane survey):
Pitch: 0.14 Roll: 0.12 Heading: 0.20
Line 9 seems a little odd, checking required.

LiDAR Calibration
Used Leica scan angle correction of -12360
Found roll, pitch and heading:
Roll: -0.000965
Pitch: -0.00238
Heading: 3E-5
Calculated range offsets as:
Range Offset A1: -2.177
Range Offset A2: -2.139
Range Offset A3: -2.145
Range Offset A4: -2.193
Range Offset B1: -2.177
Range Offset B2: -2.244
Range Offset B3: -2.172
Range Offset B4: -2.138

LiDAR Calibration
Updated average (and standard deviation) absolute offsets with GCPs
750 m: 3.2 cm (3,0 cm)
1350 m: 5.8 cm (4.6 cm)
2500 m: 2.4 cm (2.3 cm)
Updated calibration files.

LiDAR Calibration
Redid calibration with the scan angle correction from Leica and updated ALSPP / alsproc calibration files.
Elevation offsets slighly larger than expected but otherwise fine.

Fenix
I'm using some fenix lines from this flight for Autoboresight. To do so I have moved the original processing to flightlines_original and updated the hdr files with the new calibration.
I have also updated the config files to point to the project directory's new location in 2015 not 2014.
