Quando si importa un CSV in QGis, è necessario specificare solo 2 colonne X e Y. Non ho trovato la soluzione per importarne 2 o più, ma sono riuscito ad aggirare il problema e vi illustro la soluzione.

Image Classification and Post-processing in QGIS : Edition and reclassification

This video shows you how to conduct a supervised classification after the image has been preprocessed and the training areas have been collected.

After classifying the image, it is often necessary to recode categories, edit some obvious errors in the result or eliminate isolated pixels. Those post-processing steps are shown in the second part of this video.
