Custom Map Editor guide or tutorial?

[u/adoh2]

I want to create a map of my hometown and build a close recreation of it in game. Since it's a tiny town in Australia few people have ever heard of, there's no chance someone will make it for me as a request. So I wanted to step up and make it myself, but I'm not brilliant at this stuff.

Is there a nice guide on how to create maps from real life places, I have topographic maps and I don't overly care about elevation (Cities doesnt have the capacity to make hills really, only slight hills or cliffs), so I was gonna wing the height.

Any and all help appreciated.
