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.

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

comment:8 Changed 7 months ago by wja

Ibis Processing

Still doing boresight.

SCT errors on lines 11 & 14 (possible due to frames being dropped).

comment:9 Changed 6 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 6 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 4 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 4 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 4 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 4 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 3 months ago by asm

Fenix1k atmospheric correction

Delivery created and ready to be checked.

comment:20 Changed 3 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 3 months ago by asm

Fenix1k atmospheric correction

This delivery has been checked and it is ready to be delivered.

Note: See TracTickets for help on using tickets.
