Thanks a lot. That is really helpful for me and gives me a lot of safety for my project.
But I just stumbled over the following: http://code.google.com/intl/en/apis/maps/documentation/directions/ At Directions Responses --> JSON "overview_polyline": { "points": There I could get an code, in which the route points should be found?? Do you think it would be possible with the following "recipe" to get the GPS-data ??? http://code.google.com/intl/en/apis/maps/documentation/utilities/polylinealgorithm.html Thank you very much!
