GB07/09, Flight day 212a/2010, Alps

[ella]

Data location: ~arsf/arsf_data/2010/flight_data/archive-overflow/GB07_09-2010_212a_Alps
Project has been fast copied to ~arsf/workspace.

Data arrived from ARSF via network transfer on 9th August 2010.

Scientific objective: Remote sensing support for research into the processes and rates of supraglacial debris cover formation on alpine glaciers, and on the response of glaciers to increases in supraglacial mass loading.

Priority: a4

PI:Benjamin Brock (and Martin Kirkbridge)
PLEASE NOTE:This project has a dual PI and we should cc Matin Kirkbridge on all emails. Data delivery should also be offered to Martin Kirkbridge, too.

Sensors:

• Eagle (12/05/11)
• Hawk (12/05/11)
• Leica LIDAR (20/09/10)
• RCD Camera (16/09/10)

Starting hyperspectral processing.

[jb362]

I'm leaving the hyperspectral processing until we have processed the LiDAR for this project since the SRTM dem is useless in such steep terrain.

[ella]

IPAS navigation now processed.
[Applanix already completed by jb362]

[emca]

Starting LiDAR processing

[iopa]

Starting camera check.

[iopa]

Camera check:

1) delete camera delivery log from photographs dir
2) exiftool sample run has used the camera_delivery.log in the readme, readme needs re-creating

All else seems correct.

Note: readme front page contains both the name of the PI as given in the application and the name of collaborator 2 who was entered as the PI in the logsheet.

[jb362]

Camera ready for delivery.

[jb362]

Iopa will be delivering this for me since I'm leaving.

LiDAR data ready for delivery check at
~airborne/workspace/GB07_09-2010_212a_Alps/delivery/20100910/GB07_09

[iopa]

RCD camera was dispatched today, 16th September 2010.

Delivery checking LiDAR

Delivery check report;

All is good and ready to deliver.

LiDAR data sent 20/09/2010

[emca]

LiDAR and Camera data have been rsync'd to
~arsf/arsf_data/2010/flight_data/western_europe/GB07_09-2010_212a_Alps

Appears to be an issue with the bandset labels in the header files; they start at 900nm which is lower than it should be. Possibly incorrect bandset selected or none specified. Will leave this until end of the year and new Hawk calibration.

[iopa]

Taking hyperspectral.

[iopa]

Hyperspectral status:

All data has been run thhrough azgcorr but the level 3's show tearings and various bad effects caused by the low resolution of the SRTM DEM that was then patched with the LiDAR
and the patching introduced great discontinuities. SRTM-only DEM previously showed even
worse effects.

In progress was the use of an ASTER DEM which would be patched to LiDAR, but before that it would be interpolated with 'cubic convolution' (through ENVI which can do this for BIL DEMs, GRASS can output BIL and then ENVI can do the interpolation and then back to GRASS for the patching),but while the interpolation succeeded the patching myself I did not succeed with and that is where this stands.

[iopa]

Hyperspectral has been processed and delivery is ready for checking.

Taking hyperspectral delivery check

[emca]

Eagle/Hawk line 1 does not process without -bend, can you remove the offending lines from the lev1 files

You've included the datum/correction file in the delivery, but its not used in the sample command - is this file needed to process the data?

Change the project code on the logsheet to GB07/09

Dem name needs to be *-aster.dem to be comply to standard

Add the SCT's to the ticket

Otherwise data looks good

[iopa]

Eagle & Hawk SCT offsets

[iopa]

Delivery fixes have been made, data is getting ready for dispatch.

[iopa]

Hyperspectral dispatched to PI Ben Brock on 12th May 2011.

[iopa]

Project has been tidied and r-synced to the repository.

[knpa]

Reprocessing hyperspectral with APL.

[knpa]

Stages 1&2 completed.

[knpa]

Stage 3 tested successfully.

There is an issue with hawk line 7 however that stopped this moving beyond lev1 - apl claims no matching sync message in nav file that matches hdr times.

[knpa]

Fixed this issue.

[knpa]

Deleted delivery and reprocessing as apl chain has been updated to generate additional masked files.

[knpa]

Re-ran stage 2 for Hawk as aplcal has been updated in relation to the bad pixel file.

[knpa]

ReadMe created, ready for delivery check.

[emca]

Delivery checked reprocessed apl data. Lev3 data looks a bit mismatched in some areas (where there is no lidar overlap) but this is due lack of good DEM coverage.

• Flight letter missing from Readme (project details + delivery contents)
• Readme: Level 3 (pg 4) gdal_translate sample command and paragraph after sample command problem with band list ("-b b -b a -b n", "b, a, n, d, s, , 3, 0, „ , 1, 5, „ , 7")
• DEM and logsheet named incorrectly (- vs. _)

[knpa]

Fixed above points.

Delivery of reprocessed HS has not been requested so this is finished.

[knpa]

Merged and deleted workspace version.
