Quelqu'un peut m'aider? Je veux faire la suivis en temps réel de bus et calculer l'itinéraire avec ma position. Merci d'avance
This tutorial might do what you would like to do Lofoli "I want to do real-time bus tracking and calculate the route with my position"
or possibly this one
or possibly this one that plots a route or track from one location to another
Do these examples help you do what you want to do?
