Note that contraction hierarchies are not tweakable as such. There are no a parameters to tweak without creating another contraction hierarchy and this is for every parameter. So every parameter will need its own profile, and these can become quite big. If you have a high power server with lots of disk space, you can create multiple sets. On a mobile phone this will never work.
If you want to create them yourselves: one for 130 km/hr, one for 100 km/hr, one for routes without toll roads, one for routes without motorways/highways, and all of these for shortest and fastest, etc. etc., you can have a look at http://project-osrm.org/ Harry Op di 24 mrt. 2020 om 14:22 schreef Stefan Monnier <monn...@iro.umontreal.ca >: > > Advantage of contraction hierarchy comes rather for long distances, but > it > > may be disadvantage in rural areas, as their road network is a subset of > > OSMAnd/BRouter. > > I guess in theory it should be possible to construct auxiliary data from > osm data, just like online routers do, and then make osmand, brouter, > and others take advantage of it when/where available. > > > Stefan > > -- > You received this message because you are subscribed to the Google Groups > "OsmAnd" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to osmand+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/osmand/jwvsghx99g3.fsf-monnier%2BInbox%40gnu.org > . > -- You received this message because you are subscribed to the Google Groups "OsmAnd" group.
