GPS basestation data acquired via ftp 17/12/12

[tipo]

Started Hyperspectral Processing.
used ppp for navigation.

[tipo]

Finished Hyperspectral Processing

[anhi]

Hyperspectral Delivery check:

• Two xml files in the project information folder, named differently but look the same.
• Line e11 join with e12 don't line up.
• Mention in Read Me the holes in the lines caused by cloud.

[edfi]

Navigation Re-processed using the new files and LiDAR started

[anhi]

RCD Delivery Created.

[edfi]

LiDAR delivery created awaiting D/C

[tipo]

Checked over lines e11 and e12 again, They don't line up with each other exactly, but there doesn't seem to be an sct value that matches up the join any better without causing distortion.

[tipo]

Checked camera delivery, no problems found.

[knpa]

Beginning LiDAR DC

[anhi]

Second Hyperspectral Delivery check

No problems found in changes made.

[edfi]

Checking single point PPP for Nav

[edfi]

Single point PPP needed to be adjusted. Reprocessed Nav and re-ran delivery. Will update ReadMe once complete

[edfi]

ReadMe adjusted. Ready for re-check

[knpa]

LiDAR delivery check complete

Looks good apart from the following:

1. In ReadMe, elevation difference between lines should have the line names from logsheet. Also appears to be one missing.

2. Minor thing but should be gap between comma and Z in "Min X,Y,Z:" in flightline statistics in ReadMe. Can fix with a find and replace in the tex file (someone should also check the script that inserts this).

3. Should probably mention that line 12 in particular has almost no data (due to cloud?)

4. Too many false positives on the classification on the lines I checked (4 & 9). Try running las_classify with less strict -isolated setting or omit entirely

[edfi]

starting to make adjustments

[edfi]

Adjustments made:

Renamed flightlines to reflect logsheet.

Had a look at X,Y,Z in latex script but it is consistent between letters (i.e. no odd spaces). Tried adding a space before z but made the reverse problem.

Added comment about line 12

Loosened use for -isolated

Created new delivery to update DEM, classification statistics etc

Ready for re-check

[knpa]

Re-checked and looks good, ready to delivery.

PI has requested that this flight be processed using the December 2012 calibration - please process the hyperspectral data accordingly.

[anhi]

Delivered LiDAR and rcd data on 05/03/2013 on disk 152 to David Pyle, University of Oxford.
