Navigation Processing
Processing navigation data.
FSF provided their basestation data. I also downloaded the following stations from OS:
- AMER
- ARDL
- CHIO
- HARD
- HART
- NEWR
- PRIS
- SANO
- SHOE
- SNEO
- SOTN
- STEE
- STRA
- TEDD
- WEIW
These basestations should cover a conclusive area between Duxford and Alice Holts.

Navigation Processing
Completed processing in POSPac using the SmartBase (multi basestation) method.
Basestations used:
- AMER
- CHIO
- HARD
- NEWR
- PRIS
- SANO
- SNEO
- SOTN
- STEE
- STRA
- TEDD
ARDL, SHOE and WEIW were not needed due to distance, HART had incomplete temporal coverage.
Lever arms were estimated as: 0.427 -0.497 -1.48
Have exported with angular offset of Z: 180 (IMU is backwards relative to Ibis and Fenix1k for this flight).

Hyperspectral & Ibis Processing
Processed Fenix1k data with three bands using boresight values from flight 2023 198 (ticket #704). Geoaccuracy looks good.
Need to calculate Ibis boresight. There is no data from flight 2023 190 (Alconbury) so will have to use 2023 143 (Siena).

Fenix1k Processing
Mapping all bands

Ibis Processing
Still doing boresight.
SCT errors on lines 11 & 14 (possible due to frames being dropped).
comment:9 Changed 12 months ago by wja
Ibis Processing
Calculated boresight from Siena (flight 2023 143, ticket #702) but the values are wrong for this flight. The sensor must have moved sometime between these flights.
Will do my best to estimate boresight from this flight's flightlines.

Felix Delivery
Ready for checking.
Note, this is just the standard delivery. Level 2 data has been requested but Ibis l1b will be prioritised first.
comment:11 Changed 11 months ago by wja
Ibis Processing
Have painstakingly found what I think is the best boresight we can do without the proper flightline configuration. Spatial offset is a few pixels (~3m) and does not seem consistant. Unfortunately I think this the best we can do without a proper boresight flight.
Processing all bands.

Ibis Delivery
Created. Ready for checking.
comment:13 Changed 10 months ago by wja
Fenix1k delivery check
Undertaken by anla.
- check_apl_cmd didn't run properly
- No project information XML
- Line 11 too large for fastQC
Zipping mapped files.

Ibis Delivery Check
Started
comment:15 Changed 10 months ago by asm
Ibis Delivery Check
-Data looks good as far as I can tell. The oxygen absorption at 760 nm is clearly visible through all data.
-There is no underflows or overflows.
-There were two screenshots for each line. Deleted duplicates labelled as UTM.
-Check_apl_cmd needs updating. I will recheck after that.
comment:16 Changed 9 months ago by asm
Ibis Delivery Check
-Mark updated check_apl_cmd, all running good.
-There is quite a bit of cloud shadows in the data, it might be good to capture that in the data quality section of the readme but it is rather obvious in the data.
-Started zipping files and will mark as delivered once completed and checked as all other checks were done and the delivery passed all.
comment:17 Changed 9 months ago by asm
Ibis Delivery Check
-Mapped files have been zipped successfully. Marking this project then as ready to go.

Deliveries Sent
Fenix1K and Ibis deliveries placed on FTP slot 17. PI notified. Deliveries finalised.
comment:19 Changed 8 months ago by asm
Fenix1k atmospheric correction
Delivery created and ready to be checked.
comment:20 Changed 8 months ago by asm
Ibis Delivery
Just noting here that IBIS flightline 12 could not be processed and delivered because there were no dark frames collected for this flightline.
comment:21 Changed 8 months ago by asm
Fenix1k atmospheric correction
This delivery has been checked and it is ready to be delivered.

LiDAR Processing
Continuing development work on this dataset.
comment:23 Changed 3 months ago by wja
LiDAR Processing
Note there is no fullwaveform for this flight, there is a Digitizer directory within the raw directory but it is empty.
Note that the presence of this file might obligate the LMS software to "try" and process fullwaveform.
comment:24 Changed 3 months ago by wja
LiDAR Processing
The LMS standard discrete data processing steps have completed. Exporting to ASCCI and LAS1.2.
Data unpacked
There are 16 IBIS lines.
Fenix1k crashed collecting 1 line and did not collected the following one resulting on 14 usable lines. Moved 1 line to a "crashed dir".
Basestation collected by NERC-FSF has been also download and added to the project.
Ibis and Fenix1k files have been renamed. Project is ready for processing.
