Best way to create open world map ca 200-300km big

Hello :slight_smile:
I would need help with the following: what would be the Best (and cheapest) method to get correct elevation data for switzerland. Specifically along train tracks. Streets would be kind of important. Everything Buildings can be built/handplaced generated doesn’t matter. I would like to have an open world map from ca Bern to Zürich trainstations to build a train simulator with mostly correct geography. Including elevation, turn rates ect…

I’d work with UE5.6 as long as possible.

Thanks for the help in advance already.

Greetings josh

Might have to work with Google Maps a bit too.

This is an awesome generator. Didn’t know this existed. Thx
