#341 assigned flight processing

EU10/01, 168/2010, Loobos — at Version 55

Reported by: jb362 Owned by: knpa
Priority: alpha 5 Milestone: 2010 data processing completion
Component: Archiving Keywords:
Cc: Other processors: knpa

Description (last modified by emca)

Data location: ~arsf/arsf_data/2010/flight_data/western_europe/EU10_01-2010_168_loobos

Data arrived from ARSF via network transfer on 23/06/2010

Scientific objective:

1.Key impact factors on CO2 and H2O fluxes
1.1 examine the influence of within-site elevation changes using flux tower observations, airborne LiDAR data, and ecosystem models data (Loobos)
1.2 develop an approach to allocate CO2 and H2O fluxes to specific tree species of a mixed forest (Norunda)
1.3 assess the influence of forest thinning on CO2 uptake (Norunda)
1.4 evaluate above findings and test transferability of findings (Tharandt)
1.5 investigate the impact of storm damage (Tharandt)

  1. Reducing uncertainty in the upscaling of greenhouse gases

2.1. develop an approach to evaluate airborne flux measurements using flux tower data, footprint model and airborne LiDAR data (Loobos)
2.2 use airborne LiDAR data to validate GLAS/ICESat for different forest biomes, where accurate tree height and vegetation cover density will be co-located with GLAS footprints
2.3 evaluate the ability of GLAS spatial sampling density to represent the wider field site
2.4 develop an approach to model CO2 and H2O fluxes on a regional scale using GLAS/ICESat data and generate key driving parameters for land-surface models
2.5 evaluate whether regional CO2/H2O flux models driven by satellite optical data can be improved by the addition of tree height information from satellite LiDAR

Priority: a5

PI: N. Kljun

Sensors:

  • Eagle (01/09/2010)
  • Hawk (21/12/2010)
  • Leica LIDAR (06/09/10)
  • RCD (26/08/10)

IPAS navigation for this project has been processed.

RINEX data downloaded from Thelma.

Applanix navigation processing now done. Files located in ARSF workspace.

Started hyperspectral processing

comment:6 Changed 14 years ago by jb362

I need to check the Sbet file times against the flight line times in PosGNSS for this project as they don't seem to match the logsheet, however the extract directory on workspace is empty so there is no saved PosPac/PosGNSS data and no raw files. I think Loobos is going to have to be re-downloaded so that I can put the raw files back into workspace and then open up the project in PosGNSS

comment:9 Changed 14 years ago by jb362

The -1.nav didn't contain the navigation data but we have used the datacube.nav file and renamed it as -1.nav. Original -1.nav file renamed as -1.nav_old.

.raw file missing for first eagle line

comment:11 Changed 14 years ago by jb362

No eagle data for flight line 1 or 9 and no hawk data for flight line 9 because of missing .raw files

comment:12 Changed 14 years ago by jb362

Actually .raw files do exits for flight line 9 on each sensor... I don't know why neither produced .tif files

Performing delivery check on hyperspectral.

comment:18 Changed 14 years ago by iopa

Results:

  1. PI name spelling in Readme front page --> should be N. Kljun
  1. Flight line 9 for eagle and hawk has raw files and lev1's, so should produce .tif's as well.
  1. Since line 1 for eagle does not have a raw file, the rest of the lines will have to shift up so there is a continuous set of lines 1-28 for eagle. For the readme, this means that the lev1's and tif's 1-28 will need to be matched with the recorded line numbers in the logsheet for lines 2-29 (1 will be 004, 2 will be 019 etc.). This therefore applies to lev1's, lev3's and readme which will need to be renamed. (all this assuming eagle line 1 can not have a lev1 and lev3)
  1. Remove any hidden files in the delivery, currently there is just .Read_Me-20100722.tex.swp in EU10-01.
  1. Remove the .tex after the pdf is produced. Also remove the .tex in the screenshots directory.
  1. Missing bin directory, with instructions on downloading azgcorr (see http://arsf-dan.nerc.ac.uk/trac/wiki/Processing/FilenameConventions#Delivereddata)

The large SCT offset for flight line 15 is due to a sync error.

The header file for eagle flight line 16 had to be corrected so that "lines = 9596", rather than "lines = 1837" as in the original header file.

Camera processing complete.
Removed photographs 1-11 as they did not cover the study area. Also removed 22, 44, 135, 136, 156, 202, 203, 221, 238, 239, 284, 285 & 292 due to under/over exposure.

comment:29 Changed 14 years ago by jb362

Everything looks fine. Should PI on Readme just be N. Kljun or Dr N. Kljun?

Doesn't really matter. Pick one.

LiDAR check complete.

-Flight logsheet misspells site name.

-Read_me document figure 1 is intensity image without vectors but the caption says it has vectors overlaid.

comment:36 Changed 14 years ago by knpa

Fixed above issues, preparing delivery to PI.

Creating hawk delivery.

comment:44 Changed 13 years ago by knpa

Hawk reprocessing didn't include dem so may be some distortion in screenshots.

One of the lines didn't process to level three due to sync error. There is therefore a screenshot missing as well (line 9)

comment:45 Changed 13 years ago by knpa

SCT for line 9 given further up as:

h9a: 1.30
h9b: 1.55

Not sure what this means...will try a range between those two figures to determine which one fits best.

comment:46 Changed 13 years ago by knpa

Had to reprocess again once more due to incorrect bands given in raw header file (one of the 233 band ones).

As well as a sync error, h9 also fails because of a turn.
Benj says that the two scts above given for this line might be because it was split in two.

Finally, found a dem in delivery directory so don't need to worry about distorted screenshots any more.

comment:47 Changed 13 years ago by knpa

There are indeed different SCTs for the two parts that line 9 needs to be separated into.
However I found them to be:

h9a: 1.30
h9b: 1.74

It is strange that the values are different. Going ahead with delivery for now but this should be investigated at some point.

comment:48 Changed 13 years ago by knpa

Hawk ready to be delivery checked.

comment:49 Changed 13 years ago by emca

Delivery checked Hawk:

Readme:

  • Readme is named -old.pdf - should this be replaced with one in the main processing folder? This one is also for the Hawk data but the mosaic jpg is not correct (looks like its for a different project)
  • Readme says SRTM DEM is included but it is not in the delivery folder. If DEM is going to be included add it to the azgcorr command & delivery contents
  • Example azgcorr command section - remove comma in "using a pixel size of 2.0m, ."
  • Should mention over/under flows in readme

Logsheet needs to be renamed from 168-10_Loobos.pdf to EU10_01-2010_168_Loobos.pdf to conform with convention

Otherwise ready to delivery.

comment:53 Changed 13 years ago by emca

Delivery checked re-processed hawk data. Data itself looks good. Ready to deliver once below items are addressed:

Updated readme needs to be moved from processing folder into delivery directory
Readme does not mention hawk bad pixel file
Readme quality section: entirity looks wrong, should it be entirety?
The PI and site name are incorrectly spelt on the logsheet
Bad pixel file is the old (incorrect) version - needs to be updated
Lev1 bil files need to be chmod'd to make them readable to all
