[knpa]

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]

[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.

Many lines are affected by low returns, due to the range gate issue or possibly glacial surface water.

Lines with little or no returns (will not be included in delivery):

008 (11:24)
009 (11:29)
010 (11:33)
011a (11:41)
UL001 (11:47)
032 (13:48)

Lines with reduced returns (will be included with warning):
011b (12:11)
012 (12:15)
014 (12:25)
016 (12:36)
018 (12:46)
020 (12:56)
022 (13:05)
024 (13:13)
026 (13:22)
028 (13:31)
030 (13:40)

[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.
