We've got Lidar data for three flightlines but IPAS for only the first two. Logsheet only has two lines recorded (and an IPAS problem mentioned) so presumably the third line was aborted and re-flown on one of the other days (218 or 219).

Turns out the first two lidar lines we have are test lines. Have downloaded the remaining three lines from Thelma (of which I think the last two are test lines again.
Also, the IPAS problem was because of a break in the data. We actually do have IPAS data for the whole flight.

The two lidar lines do appear to have an offset between them (order ~50cm in places, though it's hard to pin down). Unfortunately they only have a very small overlap region and that's at an angle (over a glacier, which obviously is neither flat nor smooth), which means I can't tell which of the potential error sources is causing it.

Photography data tagged using log file since keep getting error that IPAS data does not overlap with photo time stamps.
