[anch]

Data location: /users/rsg/arsf/arsf_data/2011/flight_data/sweden/EU10_01-2011_178_Norrunda

Data arrived from ARSF via network transfer on 13/07/2011

EU10/01 Scientific objective:

1. To provide better understanding of the key impact factors on CO2 and H2O fluxes of mixed forest stands

2. To reduce uncertainty in the upscaling of greenhouse gas fluxes to a regional or even global scale.

EU10/01 Priority: a5

PI: Natascha Kljun

Sensors:

Camera (26/07/11)
Eagle (09/09/11)
Hawk (09/09/11)
LiDAR (09/09/11)

[anch]

Starting navigation processing

[knpa]

Created binary dem for HS use at ~/dems/sweden_norrunda

[anch]

Finished navigation processing.

Created SOL file, camera.sol file and sbet

[knpa]

.las files created

[adbe]

Started hyperspectral processing.

Renamed hyperspectral RAW files (Added VNIR and SWIR) to generate runscripts.

[jaho]

Removed camera images 1 - 12 (taken before the flights).

[adbe]

Processing Hyperspectral-found heading offset in flightline 34

[knpa]

Correct PI name (Klujn to Kljun)

[jaho]

Camera is ready for delivery check.

[adbe]

Hyperspectral is ready for delivery check

[knpa]

Finished Camera delivery check. All looks good and ready to deliver apart from:

• PI name is spelt incorrectly (should be Kljun)

[jaho]

Corrected PI name in both camera and hyperspectral ReadMe.

[emca]

Delivery checking hyperspectral data

[emca]

Hyperspectral delivery check complete.

DEM and logsheet names need to be changed to match naming convention. Also update readme for DEM name change.
Readme is missing full stop at the end of the section on 'Quality and issues with data'.
DEM section seems squashed together like the spaces between paragraphs have been removed - maybe check this.
Logsheet is missing a lot of information (PI, proj code, comments etc). This needs to be filled in. The information is available from the Ops version.
Apl mapping guide is missing from docs.
Project information xml is missing.

Data itself is fine.

[jaho]

Camera sent to Natascha Kljun at 26/07/2011.

[adbe]

• Have renamed DEM and logsheet
• Fixed the heading offset in the final flight line
• Added skips to the tex file
• Added information to logsheet
• Added apl mapping guide
• Added xml file

[knpa]

LIDAR - QC of horizontal and vertical discrepancies. All looks fine apart from last two lines (12:04 Nor1 & 12:15 Norx) which have horizontal discrepancies.

[knpa]

LIDAR delivery ready for checking at: ~knpa/2011_arsf_data/sweden_svalbard/EU10_01-2011_178_Norrunda/processing/delivery/EU10_01-178-lidar-20110905

[adbe]

Logsheet has Carl Jozef as pilot
Other than that the data is ready to deliver

[knpa]

Above fix made.
LiDAR and Hyperspectral delivered today (09/09/11)

[mark1]

Hyperspectral hawk bad pixel files and XML files have been re-created and re-delivered to PI (via email). This corrects sample number in bad pixel text files and Eagle IFOV value in XML and extra comments included.

Beginning archiving.

Archiving preparation complete.

[dac]

PI requested full waveform data - is available so just needs to be processed.

Starting processing now.

LiDAR Reprocessing

Last two lines have pitch and roll offset, this is particularly large on last line. Was the case for previous delivery but will try to improve before delivering again.

There are no values correct for the last two lines lines: LDR110627_120528_1.LAS and LDR11062_121603_1.LAS
I have tested many different settings on the parameters but nothing fixed it. It looks that it was a problem with the sensor (maybe timing?) as the error resembles to a heading error (you can fix the pitch error for a specific area but not for the headline). As the last line was duplicated it will not be included. The other line is included with default offsets but the overlap is not correct.

Will classify and create delivery.

[asm]

LiDAR Reprocessing

Created full waveform (note there were recorded 17 or 18 with the repeated one but that will not be delivered) and trj files. Classified point clouds and run the classification over full waveform. Creating delivery.

[dac]

Full waveform files weren't named correctly. Mark fixed and generated a readme.

Starting delivery check.

[dac]

LiDAR DC

• Offsets were missing from Readme, regenerated using script.
• Added footnote to readme 'Formerly NERC Airborne Research and Survey Facility (ARSF)'
• Added note "For 17 of the 33 total lines full waveform data is available". Should mention in delivery email there isn't waveform data available for all files.
• When I checked with waveviewer there were a lot of missing waveforms in the LAS1.3 files, will mention in delivery email as well.
• Patched DEM extends quite about outside LiDAR bounds - isn't too bad though so OK to leave as is.

Ready to deliver.

[dac]

Delivered reprocessed data via FTP (slot arsf20). Sent email to PI.
