Good point! I've already expanded the area from something much smaller (so to go to the National Stadium and so on). The first draft is easy, since Opus 5.5 is good at working with open data and checking against it.

What takes much more time is polishing. Sometimes things are jagged or wrong, streets are disconnected, some tree crowns float in the air, and bridges look like they’ve been hit by an airstrike.

I check things manually, compare them with photos, etc.
