Really cool. I can see some issues, like Starr King park turned into a lake for some reason, but it’s so much fun to look at. Do you have any way to patch errors and discontinuities at the tile boundaries?

yeah, there are a ton of issues especially around water. I've documented a bunch of them here: https://sf.isopolis.city/dev.html

I tried out a few ideas, but i think better training data around water will help a LOT.
