From Gary 05/01/2016 "all LiDAR and RCD to be processed. Customer to decide regarding Fenix data."

Fenix

Replaced wavelengths and ran through radiometric calibration using aplcal to get a better idea of data quality.

Fenix

Level 1b files sent to PIs via FTP for quality checking before proceeding with processing.

Navigation processing

Basestation PPP result for BLAP (same as 290a)

lat 53 46 36.94753
long -3 02 05.890607
height 66.2

Navigation processing

Reduced elevation mask to 8 degrees. Apart from a couple of spikes where horizontal separation goes over 0.05 m looks good.

comment:9 Changed 8 months ago by dac

Hyperspectral

Found SCT values:

Flightline Fenix SCT
1 1
2 1
3 1
4 0

Mapping all bands.

Hyperspectral

Started creating delivery.

Lidar Processing

Not many buildings in overlaps, but boresight pitch and roll values look fine.

comment:12 Changed 8 months ago by lah

Lidar ready for DC

  • Did quite a bit of manual classification
  • Renamed lidar mosaic to *intensity.jpg
  • Removed Eagle & Hawk page from logsheet

Owl is ticked in logsheet but was not collected...
Do we still need Eagle & Hawk in by default?

comment:13 Changed 8 months ago by lah

Fenix DC

  • Need to regenerate screenshot mosaic as wrong sct for line 4 (mapped files look ok)
  • Needs a readme
  • I've copied logsheet without Eagle & Hawk from lidar delivery (should untick owl as no data?)
  • Should we mention new sct metho? (Has 2016 DQ report been updated?) 2015 DQ report also has ARSF instead of ARF.
  • Sensor operator is wrong in xml files. Need to remove for 2016?
  • Need to remove wrong line 4 from navigation directory
  • level 1b mask & bad pixel method files are wrongly named. Should not have .bil in the middle. Were these manually renamed? Can't run check_apl_cmd until fixed.
  • line 1 is very low intensity and noisy, will need to mention this in the readme. (dropped frames as well)

Done

Needs a readme

Have created

I've copied logsheet without Eagle & Hawk from lidar delivery (should untick owl as no data?)

Thanks

Should we mention new sct metho? (Has 2016 DQ report been updated?) 2015 DQ report also has ARSF instead of ARF.

Will also include 2016 DQ report before delivering and include note in Readme. Will stick with ARSF for 2015 DQ report.


Sensor operator is wrong in xml files. Need to remove for 2016?

Fixed, and default has been removed from scripts.

Need to remove wrong line 4 from navigation directory

Fixed

level 1b mask & bad pixel method files are wrongly named. Should not have .bil in the middle. Were these manually renamed? Can't run check_apl_cmd until fixed.

Have fixed

line 1 is very low intensity and noisy, will need to mention this in the readme. (dropped frames as well)

Have added note about low intensity and dropped frames to readme (same text as 290a)

Ready for delivery check.

LiDAR Delivery Check

Changed readme as ASCII files are supplied (was built using new template, where we won't supply ASCII data). Kept las filter command rather than ASCII instructions.

Updated logsheet to untick Owl and remove Eagle and Hawk pages (need to update template).

DEM compare results.

Min:            -31.6177517089844
Max:            30.7861675109863
Sum:            23971.1498382134
Mean:           0.636143247126305
Median:         0.160172
Absolute mean:  4.02275398384428
Std deviation:  4.71167919897178
Total cells:    1121875
Non-null cells: 37682

The ASTER DEM the LiDAR is patched with is very noisy (same as a lot of the UK). Will add note in readme, also providing EA LiDAR so will generated patched DEM using this + SRTM.

No other problems found. Ready to deliver.

Hyperspectral DC

Read me looks fine. The aux.xml files in flightlines/mapped should be removed before zipping.

check_apl_cmd commands ran fine.

comment:17 Changed 8 months ago by dac

Hyperspectral

Removed aux.xml files. Started zipping mapped files.

comment:18 Changed 8 months ago by dac

Hyperspectral & LiDAR

Delivered via FTP (arsf2). Added note about SCTs in email. Will send 2016 data quality report when ready.

Note: See TracTickets for help on using tickets.
