How do you map an area with inconsistent curved space?

a year ago by IndigoGolem to c/mapmaking

I'm talking more about maps on the scale of a country or continent than a city or dungeon here.

How do you show that a mapped area has sections of more positively or negatively (spherical or hyperbolic) curved space, besides crocheting the map and actually adding more or less surface area to those parts? Actually, that might not be a terrible idea.

My only other idea is to add a grid over the whole map and distort it in those places, make it look pinched or like a bubble in the map. Is this something anyone here has already found a good solution for?

Check out https://en.wikipedia.org/...

But since this is probably going to be a fictional map, I'd just put on a square grid/hexes that will be used for calculating movement without the projection

If you want to have a hole in the ground, check out https://en.wikipedia.org/...
Adding lines themselves might be tricky. I think I would rather open the map in GIMP and modify the colour of the area with a mask layer. I guess there should exist some map software where you could just "click and carve" but I haven't heard of it
