Testing on India osm data (400 MB routerdb)
FileStream stream = new FileInfo(@"D:\Source\Routing\data\india-latest.routerdb").OpenRead(); RouterDb routerDb = RouterDb.Deserialize(stream); stream.Close(); Router router = new Router(routerDb); Profile profile = Itinero.Osm.Vehicles.Vehicle.Car.Fastest(); RouterPoint routerPointStart = router.Resolve(profile, 32.732998f, 74.864273f); RouterPoint routerPointEnd = router.Resolve(profile, 8.088306f, 77.538452f); Route route = router.Calculate(profile,routerPointStart,routerPointEnd);
router.Calculate working for short distances like 200km - 300 km, but it does not work for long distances like 3000km, it takes long time and finally gives "Out of Memory exception". What could be the reason?
Doing routing on such long distances is best done using contraction, check the documentation here:
