RCD Delivery Check

Ready to deliver. Two minor comments:

• Needed to copy Readme into delivery directory.
• A lot of the images are cloudy (as noted in the Readme). I would say 106 and 291 fall into the 'significantly affected' by cloud coverage but they still have some usable pixels so OK to keep.

apl was returning the following error when processing line 12:

No navigation file found to match times in /users/rsg/arsf/arsf_data/2014/flight_data/malaysia/RG13_06-2014_291_Danum_Valley/hyperspectral/fenix/ for FENIX291-14-12

Solved this by adding

nav2_args_extra = -nav /users/rsg/arsf/arsf_data/2014/flight_data/malaysia/RG13_06-2014_291_Danum_Valley/hyperspectral/fenix/FENIX291-14-12.nav

Handing project over to tec. Best pitch and roll values found so far for first two lines:

Pitch: -0.00063
Roll: -0.006095

[dap]

Fenix Processing

Have looked at the raw flight lines (lines 1-7, 1131-1138) duplicated in flight 293 in FastQC in both flights. The ones collected in flight 293 are less affected by cloud so will not process lines 1 - 7 for flight 291.

Finished finding roll/pitch, was quite difficult, as there was no houses or decent structures but apart from the first two lines, the rest of the flight was rather consistent.

LiDAR Delivery Check

Beginning delivery check.

LiDAR Delivery Check

• Roll/pitch offsets seem good.
• Part of flight line 21 seems to have a kink in the end of the line. Dan suggested that this is to be trimmed off. I tried to process the hyperspectral flight line 21 and it didn't process (not a problem since it was a duplicate anyway). You'll also need to mention this in the data quality remarks.
  • Trim was done during delivery check, the new flight line looks fine.
• Classifications are good.
• Ran unix2dos on the ascii flight lines.
• Add cloud, lack of buildings and kink trimming (mentioned above) to data quality remarks.
• DEMs will need recreating due to the trimmed flight line (don't forget to also trim the resolution in the new DEM header).
• demcompare.py was not run as the DEM will need re-producing.
• Screenshots look fine, but I would suggest regenerating flight line 21's screenshot.
• laszip caused no errors on the full waveform files and they opened fine in Wave Viewer with no errors.

I'll recheck once the above issues have been seen to.

[dap]

LiDAR Delivery Check

• Renamed new read me so that it follows proj_tidy regex.
• New data quality remarks are fine.
• Trimmed the resolution in the UTM DEM header to 2.0

Looks fine, ready for delivery.
