[adbe]

Data location: /users/rsg/arsf/arsf_data/2011/flight_data/uk/GB11_05-2011_292_London

Data arrived from ARSF via network transfer on 18/11/2011

GB11/05 Scientific objective: Atmospheric flight over London.

GB11/05 Priority: not_required

PI: Benjamin Barratt

Notes: Atmospheric flight over London, no processing required. May be useful to some people though - specifically OS.

Sensors:

Camera (23/02/2012)
Eagle (23/02/2012)
Hawk (23/02/2012)
LiDAR (23/02/2012)

[emca]

Processing navigation data. No base station data available on smart net for this day. Used Download Service Data within GrafNav, got two base stations but they gave poor result, in fact no solution was found.

Processing using PPP which gave a surprisingly good result and is within the error threshold levels.

Going to process the LiDAR data (there is only one line) using the PPP results but will also check other sources for base station data.

[emca]

Didn't find any additional basestation data.

Only one LiDAR line, this line overlaps with data from day 285, 286 and 290 (#425, #426, #427) so checking against those lines as part of QC.

Also processing Camera and Hyperspectral data.

Camera ready for delivery check

Having difficulty processing the hyperspectral data as the line is very long and the resulting tif file doesn't open in gtviewer (seg fault)

Processing smaller sections of the line with different sct values, hopefully the same sct offset will be found for the entire line.

[emca]

Downloaded leica log files from Thelma, as they were missing.

Generated logsheet using these log files.

Starting camera delivery check.

[knpa]

Delivery check complete.

No problems found, camera ready to deliver.

[emca]

Processed LiDAR and Hyperspectral data. Preparing deliveries.

Hyperspectral SCT offsets:
Eagle +0.03
Hawk +0.01

Compared LiDAR data to overlapping parts of the other London data, this line was found to be ~25-30cm higher than the other lines. This is thought to be due to the navigation data.

Eagle/Hawk ready for delivery check

[adbe]

Delivery checking hyperspectral

[adbe]

Hyperspectral Delivery Check:

• Mention in ReadMe that eagle first and last bands are blank (0, 64)

Otherwise, ready to deliver.

[adbe]

Delivery checking LiDAR

[adbe]

LiDAR delivery check:

• There are some gaps between the full waveform data
• Everything else is ok

[emca]

reprocessed the fwf data so there are no gaps

[adbe]

Checked full waveform files, no problems
Ready to deliver
