Processing the LiDAR calibration.

Started with the navigation data but had some problems getting an adequate solution. Emailed Leica support to see if they can help.

[emca]

Ops are going to attempt to fly another calibration over Little Riss on Saturday (12/05/2012) so if that is sucessful then won't proceed any further with this data.

[emca]

Leica got back about the nav data and have been able to get an improved solution - contuinuing with the LiDAR calibration.

[knpa]

Proceeding with HS calibration.

[knpa]

Found SCTs for lines to be used in boresight:

	E	H
1	-0.03	-0.03
2	1.86	-0.06
3	0.01	-0.06
5	0.00	-0.03
6	0.00	-0.06
7	-0.02	1.82

Lines E2 and H2 have no sync messages.

Boresights found: (P,R,H)

E: -0.30 0.22 0
H: -0.33 0.28 0

[emca]

Processed the LiDAR calibration

Couple of points to note:

• the roll error is still evident in this data - emailed Leica support but not heard back from them yet
• due to lack of ground control points at nadir the range correction needs to be verified against another dataset (a cal flight over little riss)
• data that is processed using this calibration should be checked carefully for any boresight errors

[emca]

Processed the day 082 data and found a slight height offset (~15cm) from the GCPs - redid the range correction using the little riss data

Camera delivery had been finalised. Had a quick look at all OK so marking as finished on the status page.
