1/3 was completely wrong, in the sense that the coordinates, country and city had nothing to do with it but THEN the sources were other buildings from the actual country and city.
2/3 got city and coordinates correct, but got the country wrong, which idk how that happened.
3/3 got country, city and coordinates correct
Pretty cool
As others have also said, the first thought when I saw 8 commits was "Oh, seems like a toy project". Only after surfing a bit around the code I saw it's more serious. Is your intention to also transform this into a platform like Vercel/Heroku?
