[knpa]

Data location: /users/rsg/arsf/arsf_data/2012/flight_data/uk/RG12_10-2012_250_Luton_Bedford

Data arrived from ARSF via SATA disk on 24/09/2012

RG12/10 Scientific objective:

RG12/10 Priority: a4h

PI: Karen Anderson

Notes: Lidar (incl. FW) is of the higest priority, followed by RCD, followed by HS)

Sensors:

Camera (30/01/2013)
Eagle (30/01/2013)
Hawk (30/01/2013)
LiDAR (30/01/2013)
FW Lidar (30/01/2013)

Base station data has been resent by Ops - original appeared to be corrupt - this one may be better

[besm]

Navigation has been processed. I have completed two versions:

• Navigation data as usual (good quality solution)
• Navigation data based on basestation data at a 30 second interval (good quality solution)

This is to attempt processing with each and see whether there is a big difference between data processing with the full basestation data and the 30-second basestation data. Relevant folders in the posatt/ subdirectory are basestation_30s/ and ipas_honeywell_30s/.

[besm]

Started LiDAR processing and found these pitch and roll errors:

Pitch: -0.003054378596439879
Roll: 0.0003787571920568071

[besm]

Completed RCD processing and readme. Ready to delivery check.

[besm]

Finished classification of discrete LiDAR points. Could now go on to create delivery with discrete LiDAR data, or wait for full-waveform processing to become viable. Suspending LiDAR processing until decision is made.

[edfi]

Starting RCD check

[edfi]

RCD check complete all ok

[besm]

Started processing LiDAR FWD.

[besm]

While checking FWD, found pitch+roll values to mismatch wildly. It turns out the first and second group of flightlines seem to have radically differing pitch+roll values. Correcting now.

[knpa]

Renamed Eagle and Hawk raws so they match and are sequential (and got rid of .1 bits caused by crash).

Eagle 8 is missing (the file numbered 8 is just 30 seconds captured in-between flightlines).

Hawk 19 and 20 are missing (from Hawk dying for this period - see logsheet)

Eagle 17 did not have any nav information

[besm]

Found pitch and roll to vary a few times. Found estimations as follows.

[edfi]

Hyperspectral delivery check completed

[besm]

Completed LiDAR which should be ready to delivery check now.

[anhi]

LiDAR Delivery Check:

• Moved FW document into delivery.

No other problems found.

[besm]

Delivered all sensors to Karen Anderson+Antoine Cottin on 30/01/2013 on disks 148+150.

[edfi]

Starting vector check for LiDAR and hyperspectral

[edfi]

Vector check complete ready for re-check

[anhi]

LiDAR vector delivery check:

• Needs to be a FW LiDAR readme.
• Needs to have a vector accuracy estimate so the readme knows the screenshots are vector overlaid.

Screenshots look good

[anhi]

HS vector delivery check:

No problems found.

[besm]

Ammended the issues discussed:

• replaced .trj files
• remade readme with vectors

[anhi]

FW LiDAR Deliver check:

"An initial QC of your data shows that it agrees with the Ordance Survey vectors on average to
within 0-2 meters." repeated in the readme under Data quality and remarks heading.

No other problems.

[besm]

Should be fixed now.

[anhi]

FW LiDAR Delivery check:

No Problems

[emca]

Archiving this project

Removed *bil + *bil.hdr files (lines 01-05) from delivery directory - they were there in addition to the zipped files.

[emca]

As mentioned above base station data was processed twice.
Not sure which base station data was used to process the lidar so leaving them both. There are two reg files pointing to different base station solutions.

[emca]

Dem has incorrect name (aster.dem). Leaving as is, to avoid confusion later.

Ready for archiving

Email sent to Wendy 15/01/2014

[dac]

Reprocessed LiDAR lines 23 and 27 in ALSPP for Steve Hancock, exporting AGC in Flight ID field and sent via FTP on 12/02/2015

[dac]

Reprocessed all LiDAR lines for Steve Hancock, exporting AGC. Sent via FTP on 06/02/2014

Archiving

Started uploading data to NEODC

[dac]

Archiving

Archived data available at NEODC - looks like old version without AGC value saved in full waveform LAS files. Will notify Wendy but marking as closed.

Archiving

Reprocessed LiDAR data has been uploaded. JSON files created and uploaded as well and CEDA has been notified (31/01/2018).
