Hi Andrew, No I had not seen that and it's really helpful thank you.
This is quite challenging to explain in an email but I will try... *Scenario:* Given a way, how can I determine if that way is part of a state or national route with a name? *Scenario in Action:* - Given the way "Mulgrave Street Gin Gin QLD" https://www.openstreetmap.org/way/31973923 - Is this part of any relation.... Yes there are 2 - First relation is the A1, is this a national/state Highway YES! because it has the route=road, network=NH https://www.openstreetmap.org/relation/198279 - Second relation is "Bruce Highway", is this national/state, NO! because it does not have a network=NH or S tag. https://www.openstreetmap.org/relation/198331 *What's missing from the above:* - The Bruce Highway relation https://www.openstreetmap.org/relation/198331 - Does not identify that it is related to the A1 - National Highway - Does not identify that south most section in North Brisbane the M1 - Does not identity that this is a State Route - *but I am unsure if it should* - Similarly, the A1 relation https://www.openstreetmap.org/relation/198279 - Does not identify that it is related to the Bruce Highway (route) - The way "Mulgrave Street Gin Gin QLD" https://www.openstreetmap.org/way/31973923 - Can't be reliably determined to be part of a state/national route and found to be named "Bruce Highway". Yes, I can say its on the A1 (national highway) but I can't say that the Bruce Highway is a State/Road route *My 2c* I'm unsure if what I am looking for should exist in a hierarchy of parent/child relations, or if it is best left to trawling through tags and finding references by convention and hope that things are tagged correctly. I kinda think the first is correct, or else why would OSM even have relations? Parent Child relation down to the way members.... - RELATION: name=National Highway; ref=A1; route=road; network=NH - RELATION: name=Bruce Highway ref=A1:M3; route=road; network=S <--- not sure if this is S or NH - RELATION: name=Bruce Highway ref=A1; route=road; network=S - WAY.... - WAY.... - RELATION: name=Bruce Highway ref=M1; route=road; network=S - WAY... - WAY... The above would allow a way's membership and hierarchy to be traversed. *Thoughts?* Please let me know CHEEERS!
