Data location: ~arsf/arsf_data/2017/flight_data/spain/ES17_126-2017_171_Alto_Tajo

Data arrived from NERC-ARF via hard drive 2017-06-30

Scientific objective: Assess changes in "Alto Tajo" Natural Park
Priority:

PI: David Coomes

The same area was flown the following data in better conditions so these data are not being processed.

Sensors:

Fenix (flown, requested)
Leica LIDAR (flown, requested, failed during acquisition)
OWL (flown, requested)
PhaseOne (flown, not requested)

Unpacking

Project has been unpacked. There was no basestation data. LiDAR failed and data is not usable for this flight season. There are 3 fenix flightlines and 3 owl lines.

Have run unpacked checks:
-All fenix nav files stopped having timestamps before the end of the files.
-All owl nav files last frames are incorrect
-3 incidents with a total of 7 dropped frames for owl line 1

Digital Camera Processing

Although processing of the flight isn't required the additional digital camera images might help with orthomosaic generation for 172 so starting processing. Converting from raw to tif.

Navigation Processing

Done and files copied across. Same problems than 172 2017 and 170 2017 that had errors in the data (Doppler LSQ solution had high RMS) and could not compute so had to recalculate Doppler for Static Data using Ephemeris. Satellite elevation mask is 8, separation is less than 0.5 metres (lat, lon and height but Fenix pixel size is 3m at nadir.
