How to snap in the vicinity of non-accessible roads #25

Closed pietervdvn closed 2 years ago

pietervdvn commented 3 years ago

I had a testcase where the target point lies close to a road non-accessible to the profile under testing. Ideally, it would be possible to snap to the closest routable road. However, this testcase would snap to the non-routable road, causing the test to fail.

To progress:

How can this be done?
Document how this can be done and make it obvious from using the API/docs how to pass the profile

I think the snapper can be configured to take one or more profiles:
