<p>I would just like to make a point about mileages/kilometrages. Physically marked positions (e.g. a milestone or a sign with an address) can not be replaced by, or derived from, the actual distance along the road.</p>
<p>These distances are not constant. Roads get diverted, split, recombined etc which can change the distance AND the zero-point. If you follow the hectometer (100m) markers on motorways in the Netherlands you will see loads of discontinuities caused by changes through the years. Occasionally, where a change makes a road longer, a whole segment is "recalibrated" to avoid duplicate markers or gaps. Where a road is made shorter, a "jump" in the values is used.</p>

<br /> <br /> this implies road markers must be present, right? Isn't this mainly about the distance from some zero point, even in the absence of road distance markers? <br /> It could be addr:kilometrage to refer specifically to this distance, but I agree on the other hand this would have a reference to kilometers in the tag, which isn't universally working well on a global level <br /> <br /> Cheers Martin <br /> _______________________________________________<br /> Tagging mailing list<br /> <a href="mailto:Tagging@openstreetmap.org">Tagging@openstreetmap.org</a><br /> <a href="https://lists.openstreetmap.org/listinfo/tagging" target="_blank" rel="noopener noreferrer">https://lists.openstreetmap.org/listinfo/tagging</a></div>
