Navigation Processing
Have received OS basestation data from BIGF. Will need to acknowledge that they supplied these data in the documentation of the delivery.
Starting navigation processing

Navigation Processing
Navigation data processed in POSPac using the SmartBase method with the following basestations:
- amer
- brdc
- buci
- pete
- pris
- sneo
- stee
- well
QC report suggests RMSE is < 3cm.

Hyperspectral Processing
There is a flightline 216-21a_FL16_2021-08-04_10-28-19/ which is missing a hdr file and will not be processed. Although this is labeled FL16, the timestamp matches FL10 or FL11 on the logsheet.

Hyperspectral Processing
All flightlines mapped with 3 bands.

Hyperspectral Processing
FPS error present in lines 15 & 16. Both FPS values in header will need decreasing.
Line 16 also has an SCT error, it is ~+0.1 seconds at the start of the flightline.

Preliminary SCT Values:
Line | SCT Error |
1 | 0.06 |
2 | 0.00 |
3 | 0.00 |
4 | 0.00 |
5 | 0.00 |
6 | 0.02 |
7 | 0.00 |
8 | 0.00 |
9 | 0.00 |
10 | 0.00 |
11 | 0.02 |
12 | 0.04 |
13 | 0.06 |
14 | -0.04 |
15 | 0.10 |
16 | 0.16 |
These are to nearest 0.2 seconds at the location targets were deployed at Rothamsted. FPS issues still need identifying and correcting.

FPS issues evident in the final three flightlines (14, 15 & 16) - this is when the integration time was changed and could be related.
FPS values have been changed in raw data header file (origional headers have already been copied).
aplnav required the use of the -firstonly flag when processing with differnt FPS values.
Line | SCT Error | FPS (if changed) |
1 | 0.06 | - |
2 | 0.00 | - |
3 | 0.00 | - |
4 | 0.00 | - |
5 | 0.00 | - |
6 | 0.02 | - |
7 | 0.00 | - |
8 | 0.00 | - |
9 | 0.00 | - |
10 | 0.00 | - |
11 | 0.02 | - |
12 | 0.04 | - |
13 | 0.06 | - |
14 | -0.04 | 99.75 |
15 | 0.07 | 99 |
16 | 0.08 | 98 |

Awaiting Delivery Check

Delivery Check
Taking over this delivery check.
-Lines match nicely, well done with the FPS and SCT
-There are a lot of cloud shadow in the data, please make a note in the readme
-Also most of the bands are underflows. This has happened in the Fenix1K but here is probably worse because of clouds. Might be worth also adding that to the note in the readme.
-Py6S spectra matches, just very low for the bands under 600nm due to underflows.
-Removed symlink of sensor fenix vector files (that were present along with the fenix1K files)
All others checks have been done and everything looks good. I will start zipping the mapped files and the project should be done ready for delivery once the readme is updated.
