[knpa]

There is a problem with the Fenix data, the .nav and .f98 files are blank.

From Tom:

Okay there was a problem with the Fenix PPS cable (bad solder joint) hence the reason that the .f98 and .nav files are empty. You will have to talk to Gary as we have been informed that there are enough ground control points on the Monks Wood site for the data to be corrected. Also the navigation data was collected and is there for the Fenix, it just wasn't included in the sensor generated files.

[tipo]

Started navigation processing.

[tipo]

Finished navigation processing, started RCD processing.

[tipo]

Started LiDAR processing.

[tipo]

Created hyperspectral delivery.

[tipo]

LiDAR has lines flown at different heights which need slightly different pitch and roll values.
High lines: p=0.00118716 r=-0.003968414

[stgo]

RCD D/c in progress

[stgo]

RCD d/c complete, no problems found. Will include in delivery this afternoon.

[stgo]

RCD data dispatched on 04/06/2014

[tipo]

LiDAR is taking a long time, as I'm having to find the roll error seperately for each line.

[tipo]

Higher altitude lines:

line	pitch	roll
150700	0.00113716	-0.00426684
151651	0.00113716	-0.00376841
152408	0.00113716	-0.00416841
153326	0.00113716	-0.00376841
153957	0.00108716	-0.00399841
154845	0.00108716	-0.00374841
155537	0.00108716	-0.00428414
160352	0.00108716	-0.00374841
161021	0.00118716	-0.00404841
165550	0.00118716	-0.00404841
164909	0.00118716	-0.00404841
164120	0.00118716	-0.00404841

The lower altitude lines are all:

0.00108716

-0.003968414

[tipo]

Lines 151651 and 154845 have areas where they narrow or taper off. The log shows that it was close to the maximum range gate, so its possible it moved slightly out of range, causing the gaps in the data.

[tec]

Beginning hyperspectral processing

[tec]

Hyperspectial processing has stoped due to lack of suitable darkframes. Speaking to ops to get data with an integration time of 20.000

Fenix data has integration times of

Int 1	Int2
20.0000	10.0000
29.3000	2.2000
25.0000	12.0000
30.0000	18.0000

[stgo]

Low altitude full waveform created.

[stgo]

High altitude waveform has been created. Lidar ready for delivery check.

[dap]

Beginning LiDAR delivery check.

[dap]

LiDAR Delivery Check
Complete. Issues found as follows:

• Contents page of readme does not have full waveform files listed.
• Link in "Data Details" section is a LAS 1.0 link, but LAS 1.2 data was processed.
• "Per flight line statistics" section is on next page from heading. I'd suggest you put the heading on the next page.
• HAWK data was collected, but typed up logsheet does not reflect this.
• Navigation directory is empty - should contain the .sol, .sup and .trj files.
• Flightline screenshots have ".txt.jpg" file extension - should be just .jpg.
• No vector screenshots - PI has not replied to knpa's email regarding this.
• Multiple LiDAR deliveries found in delivery directory - please delete one.
• Line 18 is oddly shaped - please comment on this in the data quality remarks.

• ASCII files should have had DOS line terminators - I've fixed this.

[stgo]

I've recreated the readme for the lidar delivery following the comments above.

The logsheet is at fault here, we can't have collected hawk data as the hawk instrument has not been installed in the plane. I think Ops meant the SWIR part of Fenix.

[dap]

LiDAR Delivery Check

Rechecking delivery.

[dap]

LiDAR Delivery Check
Completed. Issues found were:

• Two LiDAR delivery directories - please remove irrelevant one
• .sup file is missing from navigation directory
• Screenshots named incorrectly - the LDR need not precede the project code in the file names.
• .sol file is named incorrectly - the Julian day should be preceded by a '_' character, not '-'.

[dap]

LiDAR Delivery Check
Complete. proj_tidy complained at screenshot of each flightline - script should be updated to not do this.

LiDAR data ready for delivery.

[dap]

LiDAR data delivered to Dr Ross Hill, 25/09/2014.
