I am a "guy in Germany" who mapped some cities in *Iran* (Mashhad [1], some major streets of Bandar Abbas + complete island of Hormuz [2], major streets in Shiraz [3]). I had the help of some locals who supplied some names for places and streets. I guessed the initial street categories from the satellite imagery which worked quite well. Mapping the road network layout even without categories and names takes about 70% of the work of capturing the streets in my opinion as adding names, categories and restrictions is lot less time-intensive once you have the ways already. Happy tracing... Don't forget about northern asian countries like Casachstan, Usbekistan, Turkmenistan... They have hi-res Yahoo coverage as well.
