Looking for high-res/vector street layouts

[Redrobes]

Open Street Map data is fully open and free - you can download the vectors and render it all yourself if you feel the need and have the ability to process the files in some meaningful way. There are lots of styles available out there for prerendered versions of it already. I have a bit of perl to decode some of the XML roads and features and render it to a bitmap but I have not done a lot of it nor made it look good because I did not have the need.

As Rwhyte says if there is some external site which has already done the decode and conversion to some easier to use format then OSM data is very thorough.

Oh and I guess I ought to mention - if anyone knows of some open vector or raster repositories of middle ages villages or more fantasy time related data instead of current time stuff then I would love to hear about that.
