MA14/08, flight day 317/2014, North Selangor Peat Swamp Forest

[dap]

Data location: ~arsf/arsf_data/2014/flight_data/malaysia/MA14_08-2014_317_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

The following webcam images were removed as they are corrupt:

141113_014456_000.jpg

OWL data were collected and are present. proj_tidy does, however, suggest that too few dark frames were collected for file Peninsular_Selangor_Paul_Aplin_0305.hdr (only 44 dark frames collected).

Sensors:

• Fenix (requested)
• LiDAR (requested)
• FW LiDAR (requested)
• RCD (requested, lower priority)

Have added a 'gps stop time' to flight line 18 .hdr file based on start time of next line, to replace the original time of xx.xx.xx.x

Navigation Processing
Started navigation processing

Basestation data
Have had to convert the basestation using teqc

Latitude	3 07 31.68506
Longitude	01 33 43.26778
ELL. Height	18.839 m

[asm]

Lidar Processing
Started. There is a lack of useful features for geo-corrections (No roofs or edges), pitch and roll errors expected to be less accurate.

[asm]

Hyperspectral Processing
Starting hyperspectral processing.

Hyperspectral Processing - SCT values
Found SCT values. Flightline 18 did not pass the navigation process.

Hyperspectral Processing
Awaiting new calibration for fenix

[asm]

LiDAR Processing
Found pitch and roll values, consistent for all lines:

Roll	-0.0061
Pitch	-0.00055

Starting classification.

[asm]

LiDAR Processing
Finished classification. Due to the extend of low clouds on flightline 011 (LDR13112_025741_1.LAS), some points could be wrong classified (vegetation classified as noise).

[asm]

LiDAR Processing
The elevation difference could not be calulated between several flightlines because the amount vegetation was dominant and therefore, they lack of usable features.

[asm]

LiDAR Processing
Delivery created.

[asm]

LiDAR Processing
Readme created. Ready for Delivery Check.

Lidar Delivery check

• Link to aster policies 404s in readme, check with dap if his changes to the template have been accepted.

• Data quality remarks:

extend - extents

"Moreover, the elevation difference could not be calulated between several flightlines because the amount vegetation was dominant and therefore, they lack of usable features."

would read better as

"The elevation difference between several flightlines could not be measured due to a dominance of vegetation masking usable features"

I still don't like several flightlines though, it would be better to specify which ones (unless its all of them)

• flightlines/discrete_laser/las1.0 should be called las1.2

• The fw_laser folder contains a las1.3 folder but there are no fw files? Same for TRJ files, I'm assuming they just weren't copied during the delivery creation procedure, these need to be classified and copied in.

Proj tidy is complaining about the naming of sol file and lidar intensity screenshot but I can't see why (they look right to me)

[asm]

Lidar Delivery check

I believe that for proj tidy the sol file should be called:
MA14_08-2014_317.sol versus the previous MA14_08-2014-317.sol
Renamed it just to check if I am right. Not a clue about the intensity screenshot.

-Data quality remarks: Corrected (Thanks stgo).
-New readme created (link to aster policies should have been solved, as far as I know it seems that way)
-las1.0 renamed to las1.2
-las1.3 has now the fw.
-trj files looked good to me.

[stgo]

Lidar
Last comment didn't post.

FW lidar is classifying on asms machine, I have updated the readme quality remarks to read a bit nicer.

[asm]

Lidar Delivery Check

Readme file and everything looking good.

[stgo]

Lidar Delivery Check

asm has fixed the readme and the full waveform files are now classified. Ready for delivery.

Lidar Delivered 18 August Via FTP

[asm]

Lidar Delivered
Problems reported downloading the data. Sent a hard drive to Dr. Doreen S. Boyd as requested (15th September 2015)

[stgo]

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

[gej]

Fenix delivery check
have copied logsheet into directory.

Flightlines 13,14,15 and 20 have high cloud cover in the lower regions. should be mentioned in readme. (20 also has a large blackspot in the screenshots, i think this is because of cloud.)

Screenshots need renaming according to proj tidy.
SRTM dems are in delivery, don't think they are supposed to be.

Data quality report needs updating to 2015 version

checked spectra, looks okay to me.

[stgo]

Fenix DC

Updated readme with new comment

screenshots renamed

SRTM removed

data quality updated

[gej]

Fenix DC

Readme comment is now fine,

Screenshot names are fine,
SRTM dem has been removed,
Data quality report is now fine and proj_xml has been changed to match.

needs spectra checking by dac or lah.

[lah]

Fenix DC - spectra
Have checked spectra for all lines and no major problems. SWIR shift looks within 5 nm, so no problem there. There is a persistent narrow spike and an occasional hump in the overlap region, both of which are in the mask region. The spike is generally larger for the early lines which have lower signal, probably due to the low sun angle.

Ready to deliver once files have finished zipping.

Fenix Delivered via FTP to Paul Aplin and via Hard drive to Doreen Boyd(University of Nottingham) on 11/11/2015

[dac]

Sent hard drive to Paul Aplin on 23/11/2015 due to problems downloading data via FTP (slow transfer speed).

Archiving

Tidied up ready for archiving. Renamed owl data. Line 21 had no hdr file so created a dummy one for renaming then removed.

Started uploading to NEODC.
