Just out of curiosity, is there a vector program that would let you have a "digital ruler" for distance? Something that can be set to show real world distances and not pixels or inches?
Basically, whatever zoom I'm at I could then just click and drag and get a measurement in miles/meters that is to scale at whatever zoom I'm at.
I have no problem using a vector map, as long as it can be tailored to fit the needs of the game. I don't want to be making calculations all the time.
Campaign Cartographer 3 does all of the above. It is a CAD based engine and its power used to be a barrier to entry, however, excellent tools and tutorials have made it very easy to create good maps.
You can measure between two points, along a path, overlay hexes or squares with a couple of clicks.
