Doesn't always work. A highway could be realigned without changing mile posts and exit numbers on unchanged portions. -- - Joseph Scanlan +1-702-455-3679 http://www.n7xsd.us/ j...@co.clark.nv.us (work) (not work) n7...@arrl.net - So he went inside there to take on what he found.

I've been researching that exact same subject, and found this: http://wiki.openstreetmap.org/wiki/Proposed_features/Milestones I haven't put it into use yet, so I'm also interested in answers on this thread!

Re: [OSM-talk] Roadside Distance Markers
If the road is mapped as a single carriageway and the distance marker is clearly visible from both sides of the road, then it would be simplest to make it a node on the way itself. Otherwise, it should probably be a separate node on one side or the other. Of course the length of a road and the distance along it can be calculated from the OSM data and do not need special nodes every 1km or so. But if the object exists in the real world, it can be mapped. -- Ed Avis ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Roadside Distance Markers
Calculating distance should be done by software by calculating and adding length of segments (ways). No relation needed. The signs however could be of navigational aid. E.g. "turn left into the minor road 500 m after the sign saying 'Skara 14 km'". It could be made to fit as an extension to the destination_sign relation [1], although the name of the tags would be somewhat non-intuitive for this purpose, and routing software would be saying "Continue on the road towards XX" for each sign even though there is no intersection or exit.

Re: [OSM-talk] Roadside Distance Markers
In the uk km 0 is often on a road that was never built! The km markers on the m6 start counting at the london end of the m1 so it isn't always the same road that the end is on On 10/23/09, John Smith wrote: > 2009/10/23 mle : >> Hi Folks - >> >> on a recent survey, I mapped some roads with modern km markers by the >> side of the road.

You may even find them more often then 1km more like 100meters If your talking about what I think your talking about, they exists down every motorway in the UK.

[OSM-talk] Roadside Distance Markers
Hi Folks - on a recent survey, I mapped some roads with modern km markers by the side of the road. How should these be mapped - As a node within the highway, or a separate single node to the side of the highway. And how to tag these ? ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
