[GraphHopper] Creating round trips for mountain bikers

[Marian Steinbach]

Hi,

as someone who knows rather little about what it takes to do routing as graphhopper does it, I’d like to ask a question out of interest: What would it take to programmatically create route suggestions for mountain bikers?

Here are some constraints I can think of:

- start and end point are the given and may be the same point
- overall distance should be within a certain range
- the more ascend (meters to climb), the better - maybe to a limit
- paths are preferred over roads, but roads are okay to some degree
- the ideal round trip (start and finish on the same spot) is circle-like, not „flat“ (i. e. A to B, then back to A). In other words: The area enclosed by the route should be big.

Does GraphHopper provide the tools to achieve this?

Thanks!

Marian
