I think GPS track logs (lists of timestamps and positions) have a 
lot of potential, because they don't only document where the 
streets are, but also which streets are used more than others, at 
what time of day they are used (workday commuting or weekend 
shopping), and which are used in various speeds by pedestrians, 
bicycles, and motor vehicles.  You don't only get a static map, 
but also traffic and demographic statistics.

This is an example plotted from Petter's track logs from Oslo,
