Im doing a WOD session and trying to get a san Fransisco city map made with all the details. Including stores,offices and trying to use the ariel view so i can actually see the buildings and construction yards and what not. But cant seem to get a offline private map tried lots of tricks but never turn out right.
including 3rd source programs
piecing it together with screenshots-always out of alignments throws whole map off
and simply trying to save it.

So im hoping someone here know any better way of going about this. I really want a accurate map for a very accurate campaign setting
