Hi, Harry. I surveyed of of this area by myself, but some streets I drew for Yahoo satellite and others by my GPS. It took about almost a month collecting data. I'm developing (still in my brain) a traffic app and I need this information. That's why I surveyed such information.

Woosh! You recently mapped out a massive area of Sao Paulo! Did you survey all of those streets yourself??

That's excellent! I've just updated the Sao Paulo wiki page with a user visualization which shows your spectacular surveying work!
