描述
Hi all,
I'm using Mapbox Navigation SDK (mapbox-android-sdk:8.6.0-alpha.2, mapbox-android-navigation:0.43.0-alpha.1) to navigate along an pedestrian itinerary set by waypoints that my server computed.
To do so, I'm using map-matching function quite successfully.
But as I was investigating some strange behaviors in my neighborhood, I wanted to quickly test the result of my map-matching on some problematic ways / nodes.
I was hoping to use a tool such as https://docs.mapbox.com/playground/directions/ to do this troubleshooting but with map-matching request.
Since such tool doesn't seem to exist I've mixed the request prepared by that tool with the one from https://docs.mapbox.com/help/demos/get-started-map-matching-api/index.html (that does map-matching but not pedestrian).
By doing so, I realized that the direction API and the mapmatching API didn't answer the same thing to a similar query :
Even if the format could be different, I didn't expect the filtering of the ways and node to be different : it seems that mapmatching is blocked at a node : https://www.openstreetmap.org/node/746410976 when direction is not.
I don't think that the parsing of the map should be any different while using both API to come up with a pedestrian path.
Am I wrong ? Is there a good reason it should be different ?
or is it, as I expect, mapmatching API being less accurate ?
where can I find the filtering rules applied in both API calls ?
Thanks for investigating,
