I would like to make a fully custom map (fictional, have to start from scratch basically) and use the OSM tools to make following things possible:
- crowd editing - the source data which is used to generate the tiles (and in the end a large continuous map) will be publicly available, anyone can make a change to it (I don't require a nice web interface like OSM has, simple github repository will suffice)
- custom rendering - I know that this is possible using custom tiles and such so this shouldn't be an issue.
Before I dive into this I would like to know if this is possible. I think tools like JOSM should be good enough for drawing the maps, then I can define my own tiles and use one of the rendering tools to display the map.
Are there any pitfalls I'm missing? Or maybe a better way to achieve this?
