EUFAR15/28, flight day 271a/2015, Mont Blanc

[asm]

Data location: ~/arsf_data/2015/flight_data/france/EUFAR15_28-2015_271a_Mont_Blanc

Data arrived from ARSF via SATA disk on 26/10/2015

Scientific objective: Hyperspectral airborne measurements over snow, glaciers and vegetation; intercomparison with ground-based
measurements and modelling.

Priority: Unknown

PI: Antoine Rabatel

EUFAR Project ID: ISOTHERM

Sensors

• Fenix (requested)
• Leica LIDAR (requested)
• Leica FW LIDAR (not requested but flown anyway)
• Owl (not requested but flown anyway)

[asm]

General processing
For general processing, will use Rinex data provided by Christian Vincent (already placed on basestation directory).

From Gary 05/01/2016 "all LiDAR and RCD to be processed"

[dac]

Fenix

Replaced wavelengths and ran through radiometric calibration using aplcal to get a better idea of data quality.

[asm]

Basestation Verification

Done. Same results than 271b:

Latitude 45 55 49.13361
Longitude 6 54 52.48238
Ell. Heightt 2133.858 metres
AntHgt 0.440m (LEIAS10, MeasDist 0.360m)

[asm]

Navigation processing

Rinex data provided do not have enough accuracy (±100 m). Will ask PI:
a) Process anyway or provide another basestation data
b) Process using closest GNSS data (Lat separation ±2 m, Lon ±5 m and height ±2.5 m)
c) Use PPP (within limits)

RCD Processing

Delivery created, ready for checking.

Navigation processing

stgo took over me (I was away) and identified the problem as an error with Leica Software when dealing with GLONASS data. An update provided by them solved the issue. He might update this with more details on the future but this is only to point out that navigation processing is now finished with good accuracy.

[asm]

Lidar Processing

Started. There are two different areas recorded, one isolated flightline with no overlaps and one large flightline that looks like an alfa letter (a loop) that overlaps with both regions.

RCD Delivery Check

Everything looks good - some really nice imagery.

Ready to deliver.

Fenix Processing

Generated config file for apl. Needed to rename raw data from FENIX241a.

Set specim_qsub to start on hot desk computer at ~ 18:00 so SCT files are generated over weekend ready for gej to take over next week.

Fenix

Checking over notes from Gary after checking screenshots and level1b data PI requested Fenix data to be processed. This was reflected in quote agreed by Gary 26/02/2016
