I still dont get it - Which relation would need this as a role? If this is a signposted destination i would expect it in the destination or destination:lane tag on the road as west e.g. destination:lanes=West;Los Angeles|East;Boston For example Mapfactor Navigator will use this to show destinations. backward/forward as role are in relation to the ways direction. A tag can either have a meaning in forward or backward or both directions on a way. There is no way a tag has a meaning in 56° left of the way. Flo -- Florian Lohoff f...@zz.de
