Description (last modified by dac)

Data location: ~arsf/arsf_data/2014/flight_data/malaysia/MA14_08-2014_318_Selangor

Data arrived from ARSF via network transfer on 05/01/2015.

Scientific objective: to characterise spatially how oil palm cultivation is degrading tropical peatland ecosystem services, using airborne hyperspectral and LiDAR imagery, and supported by an intensive field campaign, in Malaysia’s North Selangor tropical peat swamp forest.

Priority:

PI: Paul Aplin

PI is happy to receive data by USB Hard Disk, network transfer or DVD
Co-I Doreen Boyd requested delivery via USB Hard Drive

OWL data were collected and are present.

Sensors:

  • Fenix (requested)
  • LiDAR (requested)
  • FW LiDAR (requested)

RCD images were requested but could not be collected due to an instrument failure.

Navigation processing

Had to split the basestation file using teqc. Command:
teqc -st 141113232000 -e 141114030000 +nav /tmp/318_output.14n Default_9488_0826_120823.m00 > /tmp/318_output.14o

basestation verification:

Lidar Processing

Consistent pitch and roll found with values:

Pitch -0.00230
Roll -0.006225
Heading -0.00008

Classification complete, currently creating delivery.

Started Lidar Delivery Check

comment:6 Changed 9 years ago by gej

Lidar Delivery Check

AGC values for FW data not saved (user_data field are 0 for min/max)

Everything else okay.

Lidar Delivery Fix

I've replaced the discrete and full waveform files with updated ones including the AGC value, this should be everything that's needed I think.

Ready for redelivery check

Starting ReDelivery Check

comment:9 Changed 9 years ago by gej

Lidar Delivery Check

Pitch and Roll values appear incorrect. Were fine before updating to include AGC values.
Not sure what has caused this, as same Pitch and Roll values were used when reprocessing with the AGC saved.

comment:10 Changed 9 years ago by stgo

Lidar Processing
Reprocessed with new pitch roll values of:

Pitch -0.00260
Roll -0.00626

Files now include AGC value in point ID and user data field.

Read Me
Need to specify N/S in projection.

Renaming
Need to rename LAS1.0 folder to LAS1.2
Rename sol file in navigation

comment:12 Changed 9 years ago by stgo

Lidar Delivery

Fixed projection in readme

Renamed sol and las folder

Fenix reprocessing

Ready for delivery check.

This delivery needs to be thoroughly checked for:

  • correct lines included
  • correct linenames from logsheet
  • data quality comments
  • spectra shifts

comment:18 Changed 9 years ago by gej

Fenix Delivery check

Screenshots need renaming,
Lines 5,6,7 have quite high cloud cover. should be in data quality report.
SCT's look okay,
Spectra looks okay.

comment:19 Changed 9 years ago by stgo

Fenix dc

fixed screenshot names

Data quality updated + name in project xml

Readme now has comment about cloud.

Fenix DC
Screenshot names now fine,
Data quality report and name in projxml are both fine now.
Readme comment looks good.

Spectra needs checking by either lah or dac.

comment:21 Changed 9 years ago by lah

Fenix DC - spectra
Checked spectra of all lines and no major problems. There is a persistent spike in the overlap region between the VNIR and SWIR bands, which is fairly small and narrow, though occasionally it becomes quite an intense spike particularly when the overall signal is low. The spectral shift is within 5 nm compared to previous data (2014 169).

Had a quick check of the rest of the delivery and all looks fine, so zipping files. (Not so keen on pick fields in the screenshots though)
