I would suggest adding a data quality remark about the blue 'tinge' that is around the edges of the photographs in to the read me as this is probably due to overexposure.

Once done, the dataset will be ready for delivery.

• Screenshots weren't named correctly - I renamed them.
• Mapped bil and header file names for line 2 still had "_p_" in - renamed these files.

Just some minor problems left to fix in the read me and log sheet:

• Data Quality Remarks section is a LaTeX section but Underflows and Overflows is a subsubsection - I would suggest changing the Underflows and Overflows section to a subsection.
• The logsheet has the legacy empty page that we used to use for the Hawk and Eagle line information - probably no point in keeping it since it's just an empty table.

Please could you also delete the previous delivery if it is no longer needed.

Dataset RG13_06-289-hyperspectral-20150220 ready for delivery when the above issues have been addressed and the SWIR offset found as a result of the calibration has been investigated.

• Have removed surplus Eagle & Hawk pages from logsheet

LiDAR Delivery Check

• Logsheet
  • No need for the Eagle/Hawk page - this should be removed.
  • Might be useful for the PI to have the #XXXX line number?
• Delivery Contents
  • Spurious temp file in ascii/ directory - probably left over from the DEM/screenshots generation? I haven't removed this as it seems to be an ASCII flight line, so unsure if needed or not.
  • Have renamed las1.2 directory to las1.0.
  • Read me document missing
  • DEM and DEM header incorrectly named - haven't renamed these as they will need to be regenerated when the LAS files have been reclassified.
  • DEM screenshot incorrectly named
• Readme
  • Unable to check as it hasn't been generated - needs to be generated before delivery (as noted above and in comment:25)
• LAS files
  • Line 11 is smaller in size and shorter in length - logsheet indicates that this flight line was aborted due to towering cumulus clouds, hence the shorter size so no problem here.
  • LAS 1.3 files open fine in Wave Viewer with no error messages produced.
• Roll and Pitch Corrections
  • Good across all flight lines (though something should be noted in the read me that there is a lack of buildings making corrections difficult).
• Classifications
  • 01 - 08 and 10 - 11 are OK
  • 11: Missed cloud at the south-westerly end of the line
  • 12: Too many points around the two big cloud patches have been falsely classified as noise.
  • DEM shows that cloud has been missed, so worth re-classifiying the above files.
• Other notes:
  • LAS files don't have a projection when lasinfo is ran (Dan looking at this).
  • Haven't run demcompare.py yet - I will run this on the new DEMs after re-classification.

Reprocessing again with bad pixels list from all flight lines (and 290's lines).

Fenix ready for DC
Same issue as with 290 creating readme - latex won't use thumbnail so used original mosaic screenshot

Converted thumbnail using convert -density 300 -thumbnail 1024 fenix_mosaic.jpg fenix_mosaic.jpg and remade readme.

Overflows and underflows are wrong I think, flight line 1 looks fine, line 2 has underflows from 530-535 and 590-621. I think the autoQC script's threshold needs to be tweaked.

Other than that it looks ok.

LiDAR Delivery Check

• Logsheet
  • No need for the Eagle/Hawk page - this still needs to be removed (copying the one from the hyperspectral delivery would suffice).
• Delivery Contents
  • Converted ASCII files to DOS line endings
• Readme
  • Mention in the data quality remarks the lack of features for roll/pitch error correction.
  • Mention in the data quality remarks the cloud coverage
  • Elevation differences are in the wrong units - convert these to centimetres.
• Classifications
  • Much better, all cloud seems to have been classified.
• Other notes:
  • LAS files still don't have a projection when lasinfo is ran but this is not a reason to justify holding back the delivery. I have checked the projection used in the ALSPP config file, which shows UTM50N was used.
  • demcompare.py returned a result of greater than 12.
  • DEM screenshot doesn't open in eog but opens in Windows image viewer so the delivery is not worth holding back over this.

Just corrections to make to the read me and logsheet then it'll be ready to go.

[dac]

Replying to dap:

• DEM screenshot doesn't open in eog but opens in Windows image viewer so the delivery is not worth holding back over this.

Fenix DC complete

Looks fine, I made a few corrections:

• Fixed typo in the name of the fenix mosaic screenshot
• Replaced instances of 'Danum Valley' in all xml files using

  find . -name "*.xml" -exec sed -i 's/Danum Valley/SAFE Area/g' {} \;
  

from delivery directory

Please change the read me site location before delivery.

Changed Readme and renamed logsheet to SAFE Area.
Other deliveries probably have Danum Valley in xml files...

• renamed screenshots
• just looking at the project.xml (and line xml) file, it's weird that it says "This is provided with the data:true" Why is the ":true" bit needed?
• I believe the lidar dem was used to process this data. Is that ok?
• Should probably mention cloud in data quality section of report, as was mentioned in previous delivery.
• All spectra look good.
• Under/overflows still fine.

Just a few things to check before delivering (with updated data quality report)

[dac]

Fenix

• The data:true isn't in the XML file, it is added by the stylesheet. It shouldn't be there - will make a note to fix. As the actual XML metadata is OK should be fine to deliver though.
• Have added sentence on cloud cover from previous readme.
• The files were processed with a LiDAR DSM by mistake - not sure why this was left in the config file (might have been me testing). Started reprocessing lines with ASTER for consistency and will replace mapped files and metadata in delivery.

[dac]

Fenix

• Reprocessed lines using ASTER DEM and replaced files in delivery.
• Check spectra against 6S - look good.
• Started zipping files.

Delivered to PI via FTP (arsf1) 21/10/2015

Owl tidying

• Removed processing/owl/* as only used in script testing, not operational processing.
• Renamed David_Coomes_Safe_0135 to OWL289-14-7 to match the rest of the files. This line appears to have been aborted according to the logsheet so was probably previously ignored. There is also no header file so it cannot be processed. Timestamp also confirms that this was collected after line 6.
