Dear GRASS GIS community, I just started working with Grass to try some object-based analysis. I do not have much experience with programming, but learning bits on the go. The segmentation test with uspo appears to have been ok, but I am struggling with the next step. I was suspecting the training vector created in QGIS wasn't meeting proper standards, but I could not find a straightforward Grass module for labeling segments/ creating a training set file.
Hopefully someone can help me out.
