Very good idea, it's like a MMORPG map that needs to be occasionally updated and it could also be used as a craft. Wonder who gets the ability to craft the map though, I'm guessing the architect? Would definitely balance the game out, being that architects rarely scout. I'm also hoping that maps wouldn't take inventory space, maybe having it be part of the GUI or after using a crafted map your GUI map gets updated and the map disappears? That way, everyone will be able to update their map by scouting, but only architects could share their maps since they're the only ones that could craft them. Hope that makes sense...
