[edfi]

Starting Navigation processing

[tipo]

the IMU failure happened between 13:22:9 and 13:32:30, line 3 does not process as it took place between these times.

[tipo]

Started hyperspectral processing

[edfi]

Starting LiDAR processing. Checking for navigation issues

[tipo]

Started RCD processing

[tipo]

Corrupt pixels found in column 0 (and on band 251 both 0 and 1)

[tipo]

Corrupt pixels found in RCD images at aprox coords
2881, 3772 to 3779, 3776

[tipo]

RCD reprocessed to remove corrupt pixels. Delivery created.

[tipo]

Waiting for Hyperspectral Data Quality Report

SCT values:
(Eagle was processed with use_nav = false)

Line	Eagle	Hawk

[tipo]

Waiting for badpixel generation to be finished.

[anhi]

RCD Delivery check:

• Tiff files are not tagged with positional and navigational data

[tipo]

Tagging fixed.

[anhi]

RCD Delivery check:

• Readme exiftool sample output does not have positional or navigational data.

[tipo]

Regenerated readme file to fix the exiftool example.

[anhi]

RCD Delivery check:

No problems found.

[tipo]

Created Hyperspectral delivery.

[anhi]

Hyperspectral delivery check:

• viewvector_list.txt files missing.
• Lines h11 and e11 do not line up with the other lines, maybe can be improved on.

No other problems.

[tipo]

generated viewvector_list.txt files.
h11 and e11 do not line up well under any SCT values. Noted in readme.

[anhi]

Hyperspectral changes check:

No problems.

[tipo]

RCD and Hyperspectral delivered to Alan Blackburn, Lancaster University, 3/7/2013

[edfi]

Ready to D/C

Due to IMU failure LiDAR data has large errors both vertically and horizontally. Additionally it appears that lines are not consistent within themselves

[tipo]

Checked LiDAR delivery, no problems found.

[tipo]

Dispatched LiDAR 16/10/2013

[dac]

Started archiving

[dac]

Finished checking data.
Removed duplicate processed data in processing directory.
Started uploading data to NEODC via rsync.

[dac]

Data uploaded to NEODC

Looking at LiDAR data for this flight compared to 2012/86, 2012/219b and 2014/83 over the same area there is quite a large horizontal offset (~ 40 m north-west). Due to problems with IMU listed in readme.
