[knpa]

France would like the flightlines divided into manageable chunks, 3 per flightline was suggested.

[stgo]

Beginning nav processing.

[benj]

Gary has confirmed that the PI would like FW LiDAR data for this flight (if we have any).

[stgo]

Nav processing complete, pitch and roll errors present of about 40 cm. Only one line of FW data, will process if it is a full line.

[stgo]

Found pitch and roll values for lines 155905 and 161200. Testing these against other lines.

pitch	0.00125316
roll	-0.004000414

[stgo]

There appears to be variable roll errors between lines 1703, 1650 and 1637. The worst appears on 1650, will attempt to fix this and see if it fixes the other lines.

[knpa]

Have created RCD tiffs.

These are affected by the same overexposure issue as here:
​http://arsf-dan.nerc.ac.uk/trac/ticket/513

France says:
"We are mainly interested in the lidar data. If the photos will be made available via NEODC, for us to access at a later stage, receiving good quality photography of a single sortie, say day 69, would be sufficient."

which suggests she is not that fussed about the photos but would still like to receive them. Since I've started processing these, I will carry on.

RCD delivery ready for checking at:

[knpa]

The photos aren't as bad as 068a, they only look mildly overexposed.

[stgo]

Changed roll value for line 165025 which appears to fix issues with the other two lines. Pitch and roll for 1650:

Pitch	0.00122316
Roll	-0.003099414

[tipo]

Checked delivery. No problems found.

Artefact in top right corner needs mentioning in readme.

[stgo]

lines 1612 and 1559 have variable roll value to other lines of 0.004001014 testing other lines.

[stgo]

roll error for line 162444 and 163738 is -0.003699414

[stgo]

roll error for line 163738 is -0.003959414

[stgo]

roll error for line 155025 is -0.003309414

[stgo]

Roll values for last three lines. Currently classifying points.

170333	-0.003809414
154612	-0.004010414
153318	-0.004272014

[stgo]

Lidar delivery created, ready for D/C. I have included comments in the readme about the splitting of lines, it would be worth checking these read ok/are correct.

[stgo]

A note on the split files: this was done with a 7.4 second overlap which should equal to roughly 500 metres of along track at 135 knots.

[tipo]

Checked LiDAR delivery, no problems found.

[stgo]

RCD and Lidar dispatched 20/06/2014

[mark1]

Edited KML file in-place in RCD delivery to correct data paths for rcd thumbnails.
