I did not see it in your text, but use of elevation during calculation<br>
of the route would increase possibilities for (at least) bicycle<br>
routing. mainly change forward and backward speed according to meters<br>
gained/descended (or changing impedance).<br>
<br>
is this also one of the goals?<br>
<br>
thanks<br>
