# Talk:Tag:highway=milestone

pk=* is French and not intuitive. I propose to use distance=* instead. See also: http://lists.openstreetmap.org/pipermail/tagging/2013-May/013539.html --Skyper 19:31, 20 June 2013 (UTC)

pk=* was older description in france (every 1km), it's now PR distance=* since years

## Kilometre as default unit

We should use the metric system as default. For milestones kilometre seems the right choice. --Skyper 19:31, 20 June 2013 (UTC)

## How to specify two distances?

Most of milestones in Russia looks like two-sided metal flag. Each side of these flags have own distance, for two directions. For example milestones placed on Russian road M-5 “Ural” contains distances to Chelyabinsk and to Moscow.

Which of distance should I put to distance=* tag? Which tag should I use for distance of opposite direction?

I also wondered this. I think a schema like distance:zero-point=* would work. F.e. distance:London=15.8 for the distance to London (with localised names, as they appear in the place node name=* tag).
I ran into such milestones on a cycleway (it used to be a railway connecting Roeselare and Ieper, so it's very straight and long). Every crossing had a milestone, with the distance to Roeselare on one side, and the distance to Ieper on the other. --Sanderd17 (talk) 16:27, 21 November 2014 (UTC)

There is some idea on http://wiki.openstreetmap.org/wiki/Talk:Proposed_features/Milestones - use "milestone:forward" or "milestone:backward" attributes. But what direction is "forward" or "backward"?--Zlyh (talk) 08:36, 28 October 2015 (UTC)

There is some old discussion about milestone:

## Node on the way or in the mark position?

What position should be the node with the information highway=milestone? --LucFreitas (talk) 15:25, 12 December 2016 (UTC)

Real position. 00:05, 13 August 2017 (UTC)
I would say on the highway. Otherwise we won't be able tell which highway it belongs to when we have 2 or more nearby highways. By using it as a separate node it will suffer the same problems from Key:traffic_sign#As_a_separate_node --naoliv (talk) 21:14, 24 October 2017 (UTC)
Isn't this corrected by having a ref tag on the milestone with the highway ref it belongs to? 21:23, 24 October 2017 (UTC)
And if the highway doesn't have a ref? :-) But "ref" in milestones has another meaning: "is optional, only to be used if the milestone actually has a reference number written on it." --naoliv (talk) 21:27, 24 October 2017 (UTC)
Real position +1. And about the relation between milestone and highway...Why not using a new relation type? BTW, this page is changed to "The node should be part of the way that represents the highway." https://wiki.openstreetmap.org/w/index.php?title=Tag%3Ahighway%3Dmilestone&type=revision&diff=1493715&oldid=1437923 --Yellowsoar (talk) 09:52, 21 March 2018 (UTC)
