Ok, I've several questions.
1) If it's possible, how can I retrieve all points (lat/lon) that belong to the road network?
2) Again, if it's possible and from what I understood from my last question, how can I find a route between two points? What kind of struture will be the output? Does it contains what kind of roads are each segment?
3) Does anyone can share with me some similar code that does what I pretend?
Oh... And thanks for your feedback!
