Duplicate Variables in MTL

[micha-silver]

Using the L1C2 (collection 2) Landsat 8, the MTL files now contain some variables twice. When the addon parses this MTL, it fails with "Duplicate Variable ORIGIN" etc. for each such variable

Here's a list of the duplicates that I found:

After removing these duplicates from the MTL, I was able to successfully run the addon.

Micha, this was on the MTL file only, right?

[micha-silver]

Yes, the MTL file.
