For the US, there is also data from the Census Bureau. It's free. It's used by the RoadMap project. http://roadmap.sourceforge.net/ At least in my area, there are a couple of quirks. Things often don't line up at county boundaries. Streets in my neighborhood are on a rectangular grid, but they aren't parallel to N/S or E/W. A street that should be straight is full of wiggles on the map. It feels like their setup uses a coarse grid aligned N/S and E/W and there isn't a clean mapping from streets in my area to their grid. (I have no idea if that really is the problem, but it's the best description I have come up with.) I find it useful for playing, especially at the price. -- These are my opinions, not necessarily my employer's.
