I can not change vector container in a new installed SNAP ver.8
It means it is possible if you change vector container after each vector digitalisation but if you digitize many vectors on in one container it is blocked.
I changed vector layer in left box “product explorer” not in “Layer Manager”
I give the students https://www.youtube.com/watch?v=cUbSYSHexDw
but Shaun digitized training files consistently and does not go back to already digitized classes
BTW is there anywhere tutorial about classification with Sentinel-2?
I have also always wondered how people do that Maybe it depends on the operating system and how Java responds to user input. There’s currently no ESA tutorial on classification with Sentinel-2, but there are a couple of others around. I can’t say much about their quality though.
