My city doesn't have home addresses listed on OSM. Can I just sorta copy/paste them from Google maps, or do I have to like physically walk around to get addresses so I'm not using copyrighted material?
It's kind of like Wikipedia, you have to cite the original source (State or council maps) rather than a 3rd party source.
The map data for my suburb is all kinds of wrong on Google Maps, there's a park around the corner from me which is marked as a house for starters, blindly copying that into OSM would be a disservice.
