Hi. doesn’t too short segments for instance less than 5 meters affect correct navigation in MAP.ME App? How much is the error tolerance in OSM navigation? Thanks
maps.me is a third party application. You would need to ask them.
Your title seems to be about position errors. Any router that cannot tolerate 5m errors is not fit for purpose given that GPS errors are sometimes that large. However, your body seems to be about how close together nodes are on ways. Any router that cannot cope with ways that have very short segments is definitely not fit for purpose in a user provided map, where different users have different views about how accurately to approximate.
I’d expect routers to route as though nodes were in the positions mapped and ways were series of straight lines, so the detailed solution may differ if there are two almost equally good competing routes.
