EU10/03, flight day 234c/2010, Lake Balaton East Area A

[iopa]

Data location: ~arsf/workspace/EU10_03-2010_234c_Lake_Balaton_East_Area_A

Data arrived from ARSF via SATA disk Q on 15/09/2010.

Scientific objective: Lake Balaton provides an ideal area for testing emerging algorithms on retrieval of in-water constituents and on mapping bloom-forming cyanobacteria using in-situ radiometric, airborne and satellite data.

Priority: a5

PI: Andrew Tyler

Note: Data is currently symlinked from ~arsf/arsf_data/2010/flight_data/archive_overflow and when this is resolved the symlinks will need to be re-directed.

Sensors:

• Eagle (27/10/2010)
• Hawk (04/01/2011)
• Leica LIDAR (Requested but low priority)
• Digital Photography (27/10/2010)

Started eagle processing.

[iopa]

Applanix and IPAS have been done. The applanix data currently in the workspace covers both this project and also 234b.
For IPAS, there is processed IPAS in 234a in the workspace that covers 234a,234b,234c.
The proc directory from there could be entirely copied over to 234c or just symlinked, your choice.

Taken camera processing.

Camera ready for checking.

All images were processed, the test images were taken earlier in the day.

Delivery checked camera imagery:
~airborne/workspace/EU10_03-2010_234c_Lake_Balaton_East_Area_A/delivery/20101008/EU10_03

All data looks good. Ready to deliver.

Found Eagle and Hawk SCTs:

	eagle	hawk
1	0.03	-0.01
2	0.05	0.00
3	0.00	0.00
4	0.04	0.00
5	0.00	-0.01
6	-0.01	-0.02

Appears to be an issue with the bandset labels in the header files; they start at 900nm which is lower than it should be. Possibly incorrect bandset selected or none specified. Will leave this until end of the year and new Hawk calibration.

Eagle awaiting delivery check.

[iopa]

Eagle has been delivery checked;
the only issue found was that fastQC gives a header-filesize error when opening e234c061.bil
but everything seems to be in order between the header values and the filesize.

Moved .tex and .cfg files out of the delivery directory.

Eagle is ready to deliver.

Eagle and Camera dispatched to PI 27/10/2010

Started preparing hawk for delivery.

Line six is coming out with strange data values in level 1 and level 3. The line looks looks similar to the lines that were processed before (i.e. it has the wrong bandset). Reprocessing did not help and can not find any reason.

[knpa]

benj and I have decided that though line 6 looks strange, there is nothing obviously wrong with it and it seems to have processed correctly (it is different from the previously processed - incorrect bandset - line 6).

Will deliver but with a warning included in Readme.

[benj]

Just to elaborate on that comment, looking at the new and old versions of line 6, there is a consistent offset in values from one to the other and bad pixels are removed in the old version (they're not in the new version because we decided it wasn't getting all of them) - if it was somehow picking up the old calibration they wouldn't be. The offset is comparable to that for line 5, as are the magnitudes.

In other words, it looks funny when we look at it in gtviewer, but I suspect this is down to scaling and possibly sun angle, the data itself looks fine to me.

[knpa]

Hawk ready for delivery check.

[knpa]

Recreating level 1's due to calibration error.

[knpa]

Level 1's put in delivery, ready to be checked.

[iopa]

Hawk delivery has been checked;

lev1's show significant underflows which is to be expected.

The data & delivery seem in order, ready to go.

[knpa]

Hawk delivered on 04/01/11 to Andrew Tyler, Stirling.
