Meaning of traning input "Type"

[FelipeSBarros]

Dear all (and @semiautomaticgit :),
I am working on a land use classification class. One point I didn't understand is the type each training input has.
It starts as "R&S" type (image 1), which I believe maening "ROI and Signature", but after while (and I didn't realized when, or after which process) it is converted to "Sig" (image 2).

Could someone explain me about it and its implications in the clasification process?
Best regards

Felipe

Hello @FelipeSBarros ,

probably the scp file got corrupted and the ROI polygons were lost.
R&S means that both polygons and signatures are present in the training input.
Only S means that the polygon is missing for that signature.

In case you have a backup file (SCP creates automatically a backup file of the training input) you could import the ROI polygons.

Best regards
