Wonderful ! Then it won't require me to wrap my old head around that.....
May be able to get something done on my android phone. I've got a good dungeon generator I've made in a similar style that allows crawling and I would like a good overland ability to do the same. If I can import the map and its JSON for data I can put a mask over the whole thing, pick a start spot and crawl, exposing the mask as I move along and when I hit a dungeon I can generate it in my program. Might be a little overly optimistic, but it may be worth a shot :D
BTW since you've already got most of the terrain stuff down, why not make a skirmish map generator in the same style ? These are the best set of easy to use tools around.....
