<div>OSRM isn't designed to provide perfect information along
the route like that - but it can be hacked to get close.
When I built out the elevation profile feature for <a
href="http://skitrails.com" moz-do-not-send="true">skitrails.com</a>,
I used a combination of a DEM in postgis along with the OSRM
route geometry to make the elevation profile, so not
directly in OSRM itself.</div>

<div>For highlighting tagged difficulty sections, what you
could try us using `piste:difficulty` as part of the `name`
attribute in OSRM - it _should_ emit a new step for each new
name along the path, so if difficulty changes, you'd get a
new step at that point.</div>
<div><br>
</div>
<div>You would need to remove the appended `piste:difficulty`
tag from any name you wanted to display on screen later on
though.</div>

<div> I would say that OSRM's step-by-step
instructions are definitely not optimized for
nordic ski trails. The route _geometry_ will be
correct, but the steps are primarily designed to
look at road class (highway=) and names - none of
the piste: tags are considered when generating
steps.</div>
<div><br>
</div>
<div> What does the optimal output look like in
your opinion? As a long-time nordic ski racer
myself, if I even bothered to use navigation, I'd
mostly only be interested in locations where there
were intersections. Are you looking to analyze
the various difficulty ratings along the selected
route?</div>

<div>Hello, <br>
Playing around with OSRM, I figured that smaller
ways seems to be coalesced with others to form a
single 'step' in the output.<br>
I can't find any parameter in the Lua config to
change this behaviour (yet).<br>
Any hint is appreciated.<br>
The use case is a short nordic skiing way with a
different piste:difficulty along a much longer
route.<br>
