But there are some issues to keep in mind, I’m not very sure it would be legal, there is so much data in Google Maps, some of the data is already in OSM and we don’t want duplicated data, not just would be needed to copy the data but to commit (or upload or whatever) to OSM.
What do you think? It would possible? It would be legal?
It would be illegal. Google’s terms specifically bar using their data to create other maps. Also most commercial web sites have conditions forbidding the use of tools to mechanically extract data. If discovered, your edits would almost certainly be removed from OSM.
