Do I then have to tell it to use elevation data when routing?
GHRequest request = new GHRequest().setWeighting("fastest").setVehicle("car");
GHResponse route = graphHopper.route(request); // Do I have to specify to use elevation data?
At the moment I get the same result no matter what I do.
The other question I have is if I should care where the cache_dir is set? It is only used on initial creation of the graph right?
This is starting to turn into another question from the original question. So I will start a new thread asking about elevation PointList -> InstructionList.
