Interesting! I know if you look back at changes in my country you can see where someone has done a massive automated load of buildings (addresses as well as the actual shape of buildings) from data published by a government department, so I guess I’m quite privileged to have such good data. I’ve corrected some but it’s been at the level of it tagging a garage instead of the house, it’s always close to correct. The main issue I have is searching up a business by name, they are only in there 2/3 of the time, but I go and add them if they aren’t.

I feel very lucky!
