Starting eagle processing.
comment:4 Changed 14 years ago by knpa
Found eagle scts for most lines but a couple don't have sufficient wobbles.
Need LIDAR to correct.
comment:5 Changed 14 years ago by knpa
Taking LIDAR.

Processed LIDAR has gaps in the data over the high areas, presumably volcano. Could be due to smoke or ice but looks to me like a range issue. Need to investigate further. The range settings in alspp look fine but Mark1 says there is a separate 'range gate' that is set manually. A record of this is kept in flightlinelog in leica/logs but this seems to be missing. Will request this file from ops and investigate further.
Note, this also occured in the other sortie of the day, 259a.

This has also occurred on flight day 258 (Am updating the other ticket now).

Phone call from Phil:
This is indeed an issue with the range gate, the plane was flying lower than intended relative to the ground due to an out of date DTM (the volcano had caused the terrain to rise).
Can't do anything about these gaps, resuming processing.

Camera delivery has been checked.
It might be worth adding a sentence in data quality remarks about images 622-625,629-631,
705-712 saying that the images are correct but the high brightness reflected from the snow has
caused the lens' shape to appear in the recorded image.
Otherwise all is good and ready for delivery.

LIDAR QC:
Vertical and horizontally discrepancies OK. Doesn't appear to be any significant consistent roll.
Currently classifying. There is a LOT of noise on all flightlines (due to Ice I think, this would be consistent with previous projects).

Finished LIDAR - awaiting delivery check.

Delivery checking LIDAR
comment:13 Changed 14 years ago by anch
LIDAR delivery checked - all looks good to go except the file
dem/README_DEM_MAY_NOT_BE_ACCURATE.txt
Which mentions SRTM when ASTER data has been used to generate the DEM.
comment:14 Changed 14 years ago by knpa
Have fixed above, preparing lidar for delivery.
comment:15 Changed 14 years ago by knpa
LIDAR and Photography data sent to M. Kirkbride at Dundee on 11/01/11
