Starting navigation processing.

[knpa]

Navigation complete.

Created sol, camera sol, and sbet.

[knpa]

Eagle 17 has a nonsense gps end point:

GPS Ending point = {209.578064, 113.273148}

[knpa]

Starting HS boresight.

Processing LiDAR calibration

Initial comparison to ground control points shows an elevation offset of ~20cm

[emca]

LiDAR Calibration:

Reprocessed navigation, improved solution but result not great. Reprocessed the LAS files and they still differs from ground control points, but less than before. Compared to ground points using lascontrol, not TScan. Will check on TScan when windows machine is free. Possibly elevation differences are due to navigation problems.

PRH values look okay - not great but reasonable.

[knpa]

Processed hyperspectral lines with previous boresight and they look fine after sct correction.

e1 (South), e2 (West), e3 (East) checked. A couple of pixels movement at edges but no worse than result of previous boresight (a bit better in fact - possibly due to a bad DEM being used last time).

h6 (South), h7 (East), h8 (West) checked - same as eagle.

[emca]

Due to the elevation differences the LiDAR calibration has been reflown on day 301 - see ticket #424

Have prepared project for archiving.
