I am looking into how to turn a fantasy map into vector tiles so it can imported into something like Mapbox but I'm getting drowned in information and I can't find the start point in the process, what software is needed (best fit for purpose) and if it's even feasible without a massive amount of work.
So, if you had created a fantasy world and mapped it out, how would you go about turning it into something that could used by ArcGIS or Mapbox? Is an image even a good starting point? Should I be looking at GeoJSON or something similar? Do I need to add a cartographic system to it so it has actual coordinates (I'm guessing that is required) and if yes, how?
I'm a programmer by trade so using APIs and various schemas won't be a problem, I'm just not well versed in the world of cartography and maps.
