Finished nav. processing, started hyperspectral processing.

SCTs for hyperspectral processing. The navigation was only valid for eagle lines 12, 13 and 15.

Eagle line 14 appeared to be positioned incorrectly, so doing its SCT would be impossible. It is not being processed, and eagle line 15 will be renamed to eagle line 14.

Flightline	Eagle SCT	Hawk SCT

LiDAR pitch and roll errors

roll: -0.001132
pitch: -0.003185

These result in good results in many cases, but in the worst cases still results in ~40cm displacement between projections. I chose these pitch and roll errors because they tend to produce good results throughout the flight with the worse results evenly spread with projection displacements roughly balanced on either side of zero. Getting better results would require assigning unique pitch and roll values to every flightline, and the loss in accuracy is probably not worth it.

RCD delivery ready for delivery check. (Forgot to note when RCD processing was started. Last Friday I think.)

[anhi]

RCD Delivery check:

No problems found.

[besm]

Completed LiDAR delivery - ready for delivery check.

[besm]

Completed hyperspectral delivery. Found that line 1 for both eagle and hawk was a (pretty useless) test line and seemed to interfere with making a good mosaic image, so I removed it based on Mark's advice.

The removed line can be found in the processing/line1/ folder, if needed.

[besm]

Started copying LiDAR and RCD data to disk 162.

[anhi]

Hyperspectral Delivery check:

• Move the logsheet in.
• Hawk line 13 sct looks like it could be improved.
• Mention the hawk level one files have some underflow - mostly on the latter bands.

It seems that I miscalculated the SCT for hawk line 13. Here's the updated SCT table.

Flightline	Eagle SCT	Hawk SCT
1	2.05	1.73
2	1.20	0.87
3	2.82	2.42
4	2.04	-0.37
5	1.98	-0.41
6	2.68	0.28
7	3.03	0.67
8	3.00	0.68
9	2.41	0.02
10	3.79	1.41
11	2.63	0.23
12	-0.04	0.71
13	-0.05	-0.68
14	?	19.42
15	-0.01

[edfi]

LiDAR D/C complete. All looks fine, ready to deliver. I agree with your previous comments about the Pitch and Roll values.

[besm]

Created new delivery with updated SCT values. Ready for hyperspectral delivery check.

[anhi]

Hyperspectral Delivery check:

• Screenshots still have the SCT values in the names.

No other problems

[besm]

Fixed. Please delivery check. (Do not run zip_mapped.sh, my machine is doing that already.)

[anhi]

Hyperspectral Delivery recheck:

No problems found

[besm]

Copying hyperspectral data to disk 161.

[besm]

Sent hyperspectral data on disk 161, and camera and LiDAR on disk 162. Delivered to France Gerard at the Centre of Ecology Hydrology at OX108BB. 17 July 2013.
