Unpacking

This is a large flight, with 827G of raw Fenix1k data.

run_unpacked_checked.py reported issue with nav times.

[wja]

Navigation Processing

Processed using KIRU basestation accessed from epncb.eu

Computed RTX coordinates of KIRU:

Horizontal sigma: 0.004 m
Vertical sigma: 0.005 m

Horizontal RMSE < 2 cm apart from first minutes of the flight (< 4 cm). Vertical RMSE < 3 cm.

[wja]

Darkframes recorded in their own separate files for this flight.

In the config, the following -darkfile argument will need to be added for aplcal for each line. E. g: cal_args_extra = -darkfile $PROJ_DIR/hyperspectral/fenix/FENIX*/*.raw

Hyperspectral Processing

Wavelengths in HDR files (including separate darkframe file headers) have been updated using replace_wavscale.py -w /users/rsg/arsf/calibration/2021/fenix1k/wlcal2b_vnir_1b_swir.txt FENIX*/capture/*hdr --final.

Lines 1 - 6 do not have separate darkframe files, these have been mapped with 3 bands.

[wja]

Hyperspectral Processing

All lines processed with all bands. Paths to seperate darkframe files input for lines 7 - 30.

Ready for checking

Note this is a very large flight (30 lines, mapped data alone is 2.2T)

Hyperspectral delivery check

• Missing project_information XML
• The mosaic image in the readme is from a different project and needs replacing

< will update further progress when finished checking L1 and L3 images >

Delivery

Added XML

Delivery
Corrected mosaic in ReadMe.

Continuing Hyperspectral delivery check

Finished viewing all files. Offset between VNIR and SWIR quite large for line 27 part 01 - should be added to readme or quality report, as it results in dodgy Spectra - this has been seen in other Sweden files also.
