-Will remove the edges.txt and fodis dir.
-Lots of underflows
-There is a lot of cloud shadows in the data, probably worth mentioning in the readme.
Everything else looking good so will start zipping files.

Hyperspectral Delivery

Mapped files were zipped correctly. Added a note about cloud shadows in the readme. Uploaded the dataset to the FTP and sent confirmation email to PI on 22/12/2021. Have a merry Christmas!
