Data location: /users/rsg/arsf/arsf_data/2013/flight_data/greenland_iceland/IG13_16-2013_201a_KNS

Data arrived from ARSF via SATA disk on 30/07/2013

IG13/16 Scientific objective: Studying glacial calving.

IG13/16 Priority: 9

PI: Adrian Luckman

Sensors:

Camera (Dispatched 05/09/2013)
Eagle (Dispatched 05/09/2013)
Hawk (Not Requested)(Dispatched 05/09/2013 with the Eagle)
LiDAR (Dispatched 05/09/2013)

[stgo]

Beginning navigation processing.

[stgo]

Nav data split into 2 sets of files. Lines 1 to 4 are in the first and 5 to 27 (28 for hawk) are in the second. These are still being processed under same day/sortie.

Second set of nav data is good. First is yet to be processed.

[stgo]

Beginning hyperspectral processing for lines 5 to 27.

[knpa]

Beginning RCD processing.

[knpa]

stgo tried to process nav for first 4 lines on logsheet but can not get anything approaching a good result.

It's not clear whether these are intended to be processed or not, stgo to enquire with ops.

Proceeding with processing RCD for the rest of the lines.

[stgo]

Hawk line 12 has a single line of pixels at it's start then looks to have been cancelled, this is noted in the logsheet. This line is completed in Hawk 13. Hawk file names proceed 1 ahead of eagle after this. (eg eagle 13 == hawk 14).

There is a 28th line for hawk because of this.

[stgo]

SCTs for processed lines.

[knpa]

Starting LiDAR processing.

[knpa]

RCD ready for delivery check.

[tipo]

Delivery checked RCD. No problems found.

[tipo]

Some hawk lines have lots of underflow. Should probably be mentioned in the readme.
Mapped eagle lines only have bands 0 and 1.

[knpa]

Created LAS files with alspp.

Lines with little or no returns:

Lines with reduced returns:
011a
011b
018

[knpa]

Lines appear to have a good horizontal overlap.

[stgo]

Recreated hyperspectral delivery with corrected eagle lines and readme.

[knpa]

Investigated some apparent pitch offsets between features. Hard to tell because of non-uniform terrain but could not find a pitch value that works for all lines so retaining original value.

Some apparent roll offsets also found, but likewise these are inconsistent between flightlines.

[knpa]

Delivery created, ready for delivery check.

[tipo]

Checked hyperspectral delivery.
Copied logsheet into delivery, renamed DEM.
No other problems found.

[tipo]

LiDAR delivery checked, no problems found.

[tipo]

Started creating dispatch.
