I want to some supervised classification via SNAP with some Sentinel2 product. As a training set I should use the data contained in a kml file, but in SNAP the vectors can be imported only as shapefile. I have tried to convert the kml to a shapefile in QGIS and actually I can then import it in SNAP, but it can not see properly the labels of the classes that are fundamental for classification. How can I solve this? @ABraun have you got any knowledge about that?
Thanks so much
