Arnis - Generate Real World Locations in Minecraft Free
arnis.app
Arnis is an open-source tool that generates any real-world location in Minecraft Java Edition with incredible detail and accuracy using OpenStreetMap data.

Select the square on OpenStreeMap and the app will generate the world directory, which can be opened in Minecraft Java Edition.

I haven’t figured out yet what’s the best world scale ratio, but visiting known locations is fun.
