hello,
i got, with this specific classification image :
PNKB_zone_classifiee.tif
an "unable to calculate" error message when trying to create roi of validation with "multiple roi creation" tool. roi appears as table in that tool interface. But the "launch" results in nothing but error message.
below print screen and debug txt
debug.txt
I think the error is coming from the image itself, because i got no problem with other images. this image was produced by a student. I tried to export it in geotif, but same problem occurs.
Best regards,
Antoine
