RCD Delivery Check

Found the following minor issues, which need to be addressed:

• Data quality remarks "Some cloud cover...": Doesn't follow on from previous paragraph. I would recommend changing this to something like "Some images are affected by cloud coverage but were not removed if there was less than approximately XX% cloud coverage. Some images were also affected by shadows due to this cloud coverage."
• Sample output from exiftool in Readme could start on page 4. Fix this by inserting the \newpage command before the \rule command.
• As above with "Image Collection" section.
• Images 1, 14 and 15, in my opinion, look overexposed - I would comment on these in the data quality remarks or remove the images and recreate the delivery.

Please address these issues, then resubmit for delivery checking.

[tec]

RCD
Fixed issues raised in delivery check. Ready for delivery check again.

[dap]

Rechecking RCD Delivery Quality

[dap]

RCD Delivery Check

Just a couple of issues:

• Images were overexposed as opposed to underexposed. Please change data quality remarks to reflect this.
• Please put latest .tex version of the readme in the processing/rcd delivery so that it can easily found and edited at a later date if necessary.

Once the above issues have been addressed, camera data will be ready for delivery.

[tec]

RCD
Done.

[dac]

Started processing Fenix data to test boresight values. Fenix wavelength scale in header files replaced (originals moved).

SCT values for lines 2, 3 and 4 ~ 0.94.

[tec]

Fenix
Starting from scratch testing new database scripts

[lah]

Fenix
Started processing with initial set of SCTs using initial boresight:

1	0.94
2	0.96
3	0.94
4	0.94
5	0.96
6	0.96*
7	0.96
9	0.95
10	0.94*

Lines 6 and 10 are still wobbly so need SCTs outside initial range. Others also don't look great in mosaic, so looking for new set.

[lah]

Fenix
Found final SCTs, making delivery.

1	0.98
2	0.94
3	0.94
4	0.94
5	0.94
6	0.04
7	0.96
8	0.96
9	0.95
10	-0.06

Fenix delivery created, ready for delivery check.

Hyperspectral Delivery Check
Starting DC

[tec]

Hyperspectral Delivery Check

• Logsheet notes fields are empty.
• Fixed a typo in readme.
• Fenix pixel size is too high in my opinion, can you send it though with a pixel size of 2.2

[lah]

Fenix

• Removed empty page from logsheet.
• Reprocessed with pixel size of 2.2 and recreated delivery.

[tec]

Hyperspectral Delivery Check

• flightlines/line_information missing f219a071b.xml
• logsheet notes fields are empty, (it needs regenerating run generateLogsheet)
• Readme missing, if it is the 20141013 one then the table listing the logsheet name vs file identifier, are you sure its in the right order?

Other than thats its done

[lah]

Fenix again

• Reprocessed line 7 to get xml file, no idea where that went to.
• Added notes to loghseet.
• Copied across ReadMe. Table is correct, lines nos. are backwards / line files start from the right.

[tec]

Hyperspectral Delivery Check
You didn't copy the new logsheet into the delivery, did that for you.

Delivery check complete. zip_mapped.sh currently running, once thats done it will be ready to be delivered to peter hunter.

[tec]

Hyperspectral Delivery Check
zip_mapped.sh finished. Ready for delivery

Beginning LiDAR Delivery Check

[dap]

LiDAR Delivery Check

• ASCII files in ascii/ need to be unix2dos'd
• Elevation differences seem to be very large and looks like there could still be roll/pitch errors between lines 09 and 10 especially. Speak to dac about this.
• There seems to be a lack of features usually used to check roll errors, which isn't mentioned in read me. Please add some remarks to that effect in the read me.
• In data quality remarks please make it clear what files you mean by "3, 4 and 5" by putting the leading zeros in, as the logsheet flight line names and the processed file names are similar.

Note, full waveform data has not yet been checked. Will run laszip overnight and check with Wave Viewer tomorrow.

[dap]

LiDAR Delivery Check

laszip produced 20 files, as expected. Wave Viewer showed that some waveforms in some of the flightlines had abnormally high peaks, possibly due to cloud coverage.

Delivery check complete. Please address issues in previous comment and resubmit for delivery check when finished.

[tec]

LiDAR
Ready for delivery check, delivery dir ending in 30

[dap]

Checking LiDAR data delivery

[dap]

LiDAR Delivery Check

Found the following problems:

• las1.2 ascii files need to have CRLF line endings - fixed with
  find -name "*.txt" | xargs unix2dos from the delivery directory.
• Roll/pitch errors look better but these data seem to have a considerably large height offset and should probably be commented on in the read me.
• No vectors screenshots - check with PI that delivery is ok to send before vector delivery if this hasn't been done already for this project.
• Multiple deliveries found in processing/delivery/, please delete old one when finished with.
• las1.3 files have some waveforms missing in the middle records (not at start or end) and some of the waveforms have abnormally high peaks. Assuming this is due to the fact that the flight lines were flown at low altitudes (c.f. 175b LiDAR 537) and large amounts of noise. May be worth noting in the data quality remarks in the read me. (Note, I looked at pre-classified las1.3 files in Wave Viewer and these showed the same issues).

[tec]

LiDAR
Done, all 3 datasets can be delivered but need to ask PI if they want vectors.

Delivery
RCD, Fenix and LiDAR delivered to Pete on 11/11/2014

[mark1]

Fenix
Fenix data needs reprocessing due to data being binned spectrally where processing used an incorrect algorithm.

Data have been reprocessed.

[stgo]

Fenix re-DC
Have checked the spectra against the example in the wiki, looks correct.

No issues with delivery, ready to deliver

[dac]

Fenix

Sent reprocessed data on USB hard drive to Peter Hunter on 31/07/2015
