GB2007/05, flight day 116a/2007, Windermere

[mggr]

Data location: ~arsf/arsf_data/in_progress/2007/flight_data/uk/GB2007_05-2007_116a_Windermere

Data arrived from ARSF via initial SATA disk transfer in June.

Scientific details: Data to inform models of potentially toxic cyanobacterial blooms in lakes. See ~arsf/arsf_data/in_progress/2007/ARSF_Applications-GB_2007/GB07-05_*pdf

Sensors

• ATM (Delivered 23/April/2008)
• Eagle (Delivered 19/March/2008)
• Hawk (Delivered 23/April/2008)

[mggr]

Corrected summary text.

[mggr]

Note that I've guessed which of 116a & 116b is Windermere and which is Esthwaite - when we process, we need to check to make sure and rename if required.

[anee]

There appear to be no satellites tracked between GPS time 381300 – 385800. This is in the important part of the flight path at the observation site.

[anee]

1st eagle nav file 0 bytes. No other eagle nav files present. Using hawk nav files in place of eagle.

[anee]

not all eagle raw and hdr files present

[anee]

Windermere and Esthwaite data are taken over one site.

[anee]

All hawk and atm data processed, some timing offsets probably required.

[anee]

GTPOFF for atm line 3, ~1.

[anee]

All atm and hawk data processed, no eagle lines processed because much of the required data is not present in the eagle directory.

[mggr]

Can't get access to daphne (ARSF fileserver) over several days, so sending an email asking.

Sidenote for the record: the gap in the applanix was actually due to the plane landing and didn't affect the relevant parts of the flightline for processing.

[mggr]

ARSF confirm that flightline 1 of Eagle is destroyed (possibly happened during QC?) and that the hdr files they have are also 0 bytes - we'll have to try and figure out how to work around this. I believe Bill has outlined a method in the azspec processing guide, but we may need an updated azspec program to do it - need to test.

For now, suspend this job. We'll reevaluate in a few weeks once we've gone through the 'easy' jobs and have the boresight sorted. At that point, we may just deliver the data we have and come back to the Eagle later.

[mggr]

Vectors available at ~arsf/vectors/from_akw/windermere

[mggr]

Could you reprocess the ATM with the updated boresight and ensure the DEM is used? Peter Hunter asked if we could deliver this soon.

[anee]

All ATM lines processed.

[mggr]

Holding while we complete the 2007 ATM radiometric calibration..

[mggr]

Please confirm status of Eagle reconstruction to Andrew Tyler in two weeks time.

[anee]

Successfully processed lines 2 and 3 using hdr files produced by taking Eagle files for the equivalent lines on flight 116b and editing the GPS time fields to match the Hawk hdr fields for day 116a. The lines and autodarkstartline fields were also corrected.

[anee]

Eagle line 3 GPTOFF ~ -0.2

[anee]

Processed Eagle flight data (lines 2 and 3 only) located in: /users/rsg/anee/scratch_space/GB2007_05-2007_116a_Windermere

Delivery directory created and filled

[anee]

directory renamed to /users/rsg/anee/scratch_space/GB2007_05-2007_116a_Windermere_Esthwaite needs to be updated in arsf directory too

[benj]

Not entirely happy with Eagle imagery (roads are too blue, rest of image seems too dark and too green), but checking as best I can against ATM, Eagle from other flights and processing through Caligeo doesn't show up anything wrong with it so I can't say it's actually wrong.

Rsynced to ~arsf/arsf_data/in_progress/2007/flight_data/uk/GB2007_05-2007_116a_Windermere_Esthwaite

Eagle data sent to Andrew Tyler on disk 5.

[benj]

Checked and rsynced to ~arsf/arsf_data/in_progress/2007/flight_data/uk/GB2007_05-2007_116a_Windermere_Esthwaite

[anee]

Processed Hawk data located in: /users/rsg/anee/scratch_space/GB2007_05-2007_116a_Windermere_Esthwaite

Delivery directory created (20080410)

[mark1]

Has been checked with some minor corrections made to Read_me.txt (using bands 30 15 7 not 5 3 2). Example commands have been checked (without a DEM) and look ok. Data has been copied over to ~arsf/arsf_data/in_progress/2007/flight_data/uk/GB2007_05-2007_116a_Windermere_Esthwaite/

Ready to deliver.

[anee]

ATM and Hawk data sent to PI.

[mggr]

Prepared for archiving (DTG, NEODC), moved to archive area (~arsf/arsf_data/complete-ready_to_archive/).

[benj]

Eagle lines 1-3 seem to be missing dark frames, see #218

[mggr]

Data already sent to NEODC for archiving.. oh dear.

[mggr]

Belay that, line 3 has dark frames. Lines 1 & 2 are zero bytes, so obviously won't have any. The .hdr files were missing, hence being detected as not having dark frames.

[mggr]

Specim lines reprocessed for internal testing with new azspec, azimport and azgcorr. Timing offsets for line 3 are SCT 1.5 for Eagle, SCT 0.0 for Hawk.

Missing Eagle line 3 hdr file should be:
