General Processing
Sent to PI ARSF data arrival notification for RANNIS15/28.

Needed to download base station information for this project. Used REYK
Basestation verification

Lon: -21 57 19.75497
Elipsoidal Height: 93.210 (metres)

Could not find a suitable solution with Ipas TC, will try Ipas Pro.

[asm]

Navigation Processing

Found a suitable solution using Ipas Pro. Also created sol file for camera processing.

[stgo]

RCD processing
Starting camera processing.

[stgo]

RCD processing

I've converted and tagged the images, creation of the delivery was fine but the readme is complaining that there are no rcd images in the generated KML file (?!) and that there has been a problem in the lidar sorting function. Looking in to this now.

[stgo]

RCD delivery

ready for delivery check

[asm]

RCD Delivery Check

Started.
-Google-earth is not loading any picture. Please double check cause could be a problem with the program installation.
-There are two additional thumbnails that are plots and do not correspond with any photograph and should not be included on the delivery (283, 284).
-Readme is missing pages at the end. It is missing pictures from 257 to 282 and general information about ARSF and copyright info.
-proj_tidy is complaning about every single file name but I can't see anything wrong, I suspect it is caused by a longer than usual project_code. Please re-check in any case.
-Some pictures are almost totally covered by clouds (217). If we are going to deliver those, a note about data quality will be beneficial on the readme file.

[dac]

RCD

The path to the images in the KML were wrong, they were relative to the top level of the project rather than the delivery folder. Have fixed and checked under GoogleEarth.

Images completely covered by clouds should be removed.

[stgo]

RCD

Fixed images and readme, new delivery created for checking

[asm]

Fenix Hyperspectral Processing

Started. Found problem with Ipas Pro navigation, will try to re-create it.

[asm]

RCD Delivery Check

All checks have been made. Everything seems correct. RCD is ready to delivery

[asm]

Navigation Processing

Have re-done navigation with Ipas TC using PPP processing instead of GNSS differential. Have saved Ipas Pro output to a different directory in case of it is needed but will need to be tidied once archiving is needed.

[asm]

Fenix Hyperspectral Processing

Found SCT values:

Flightline	FENIX
1	0.94
2	1.06
3	0.91
4	0.95
5	1.04
6	0.98
7	0.97

Flightlines are fairly big on size, will split and create delivery.

[asm]

Fenix Hyperspectral Processing

Have created the delivery and generated a readme file. Also realised that screenshots were mixed and did not match with its level3 and have renamed manually (also sct values were present on the name). Fenix is ready for Delivery Check.

[asm]

Fenix Hyperspectral Processing

Solved some issues from delivery before DC also presented on 241a and noticed during DC.
-Removed fodis directoy
-Solved apl commands for bot config file and readme.

[dac]

Delivery

Sent RCD to Gro Pederson (University of Iceland) on a hard drive (21/12/2015). Also placed on FTP server (arsf4) for early access.

[dac]

PI prefers delivery by hard drive

[dac]

Fenix

Have changed status back to processing as will need to be reprocessed once updated GPS basestaion data are available.

[dac]

Marking as blocked - still waiting on GPS data from IMO.

Best solution found using MJSK. Best solution found using MJSK. Copying files and will rename old basestation and ipas_honeywell to old_nav_basestation (Please clean after processing, before archiving).

[asm]

Fenix

Creating a new hyperspectral delivery with the new navigation.

[asm]

Fenix

Delivery and readme created. Awaiting delivery check. There is also an old delivery created with the old navigation that has not been checked and delivered. To be sorted out on the future.

[dac]

Fenix Delivery Check

Starting delivery check.

[dac]

Fenix Delivery Check

Generally looks good a couple of comments:

• Need to remove old delivery
• Lots of clouds and cloud shadow in data.
• check_apl_cmd doesn't run - commands not defined in config file.
• proj_tidy gave a lot of errors - I think due to length of project name.
• Py6S script didn't find many vegetation pixels - the ones it did looked good though.
• The readme lists f24207 as having 2 parts in the table with corresponding lines in the log sheet but there is only one part.

[asm]

Fenix

All comments suggested during delivery check have been addressed.

[dac]

Fenix

Marking as ready to delivery. Have started zipping mapped files.

Lidar Processing

Lack of features and high cloud cover so pitch and roll corrections difficult, found values of:
roll:-0.001

Classifying now.

Owl Delivery Check

• Should mention cloud cover and cloud shadows in readme as quite bad for this flight.
• Removed an *aux.xml file left in mapped directory
• The project name is listed in the logsheet as HEKLA RO28, R028 is just the identifier used by BAS it doesn't need to be in the project name. Has been used for previous deliveries so might as well keep for consistency though.
• check_apl_cmd ran through OK
• SCT values look good.

Zipping mapped files. Once note about cloud cover has been added to readme ready to deliver.

ReadMe updated.
Mapped files have been zipped.
