[GraphHopper] Looking for an engine for horse (and hiking) routing

[Nop]

Hi!

So far I have spent a lot of time creating (IMHO the only) maps for 
horseback riding, also useful for hikers. [1] There is a Garmin map, but 
it is not routable, as common routing engines are built for cars and 
tend to ignore differences in elevation and other important factors, 
thus creating disastrous suggestions for hikers or horses.

I'm playing with the idea to extend my work and try to create really 
usable routing for horses (which would likely also work for hikers). In 
order to not re-invent the wheel first, I am looking for a suitable 
routing engine to base the project on (and a helpful community to 
explain a thing or two).

For a suitable routing you'd need to
- add elevation data
- create directed edges with different weight uphill and downhill
- interpolate additional points for elevation samples on long edges
- calculate weight based on road conditions (tracktype), elevation (and 
some other factors)

I noted the post "Routinggewichte". It's missing the start of the 
conversation, but it sounds very similar. If you're interested in 
elevation data, I am using both SRTM and CGIAR DEMs as data sources for 
the calculation of contour lines in my map compiler Map Composer [2] and 
I would like to base routing on CGIAR also.

Did I understand that correctly?

bye, Nop

PS: Does the default area "Unterfranken" mean that you are active in 
that area?
