I am converting a Shape file centerline map to OSM for use in Graphhopper. Where I have segments that are one way, I find the segments are often drawn backwards, but the oneway flag is correct in that it says which way (from start to end or from end to start).
If I leave the ways as they are, and tag ways that are one way from start to end as “yes” and tag those that are one way from end to start as “-1” will graphhopper properly support this? If not I will add some additional automation to my conversion to “reverse” any way that is oneway from end to start. I don’t want to add this extra work if not necessary though
