But trying to resolve a point that is clearly in the network still fails. I wanted to create a database for a pedestrian route. So far I have not assigned anywhere that this is limited to pedestrian but I got no limitations at all (as far as I understand). Using only a blank profile (might this be the problem?)
Error (Coordinates replaced by placeholder):
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Itinero.Exceptions.ResolveFailedException: Could not resolve point at [XX.XXXXX, YY.YYYYY]. Probably too far from closest road or outside of the loaded network.

// calculate a route.
var calculatedRoute = router.Calculate(routingProfile, start, end);
Could it be that the given profile is not suitable? Does it need specific characteristics?
//edit: Answering my own question: Adding
fixed it. Is this the correct way? What about an edge that is possible for all profiles? Is it then "residential" instead of "pedestrian"?
Hi.
Refering to https://github.com/itinero/routing/issues/222 I've implemented my own custom routerdb with custom nodes and edges. So far it seems to work.
But trying to resolve a point that is clearly in the network still fails. I wanted to create a database for a pedestrian route. So far I have not assigned anywhere that this is limited to pedestrian but I got no limitations at all (as far as I understand). Using only a blank profile (might this be the problem?)
