I'm looking for free software, preferably open-source, that would allow me to create maps for my story. I guess what I need is a tool that would allow some measure of 3D modeling.
Features I would very much like:
- Fiddling with elevation
- Drawing rivers, and making sure they don't do silly things like flowing upwards.
- Marking precipitation, so that, for myself, I know "region X is arid".
- Marking roads, cities, forests, etc.
- Measuring distances
- Generating some sort of 2D map out of the 3D model
Is there anything in existence that's sort of in the right direction, perhaps some tool for RPGs?
I will need a map with my novel, eventually, but primarily this is for myself and my worldbuilding at this stage: I want to make sure I'm consistent with distances and with routes. Also, the story is relatively heavy on geopolitics, making a map rather critical for the creative process. (This is apparently what happens when the MC is the king, and he does actual governing.)
