i have a question regarding routing abilities, and if it would be possible to make it happen
for years now i am using Garmin Basecamp to create offroad(ish) routes for motorcycle tours (with OSM maps). Usually i do it by selecting the smalles possible roads and hope to get at least a gravel road. Since these tours are not really to reach a certain goal but more oriented to have fun while driving i was wondering if it would be possible to use an automated routing process do to this task.
Kurviger.de does have the feature to avoid highways/mainroads etc, but still is kind of using more or less the direct way from A to B.
So i was wondering if it would be possible to to have even more customization possible? Since it is using graphhopper as routing algorithm, it should be possible to have more flexibility there right? for example explicitly deny (and not only avoid) certain road types and or make a finer dicision of what road type is what (in most places OSM data is well equipped for that)…
If there are any ideas to achieve sth. like that, it would be nice to hear about it!!
Thank you so much in advance
