Distance Marker tag

For noting the existence and distance of a marker or feature on a roadside, railroad, trail side or other route.


Many routes have markers along the way. Some of these markers are historical such as stone markers along an old road. Some are functional such as markers along a hiking path. My original intent was to have a way to note the existence of features along a railroad right of way for railroad fans. I see now that there are many other, similar applications for a tag like this.

One example, a local road has old stone markers at every mile point. Some are missing and some are hard to find (often because the road has been moved). It would be nice to have a way to show them on the map with an icon.

A second example is the railroad. All of the features along the tracks, such as signals, bridges and sidings are denoted by a mileage number. These numbers are constant even though the tracks have changed over the years. Now the number may not match the exact mileage to the original point for all features.

This is not intended to be used to mark the actual mileage markers that occur on many roads at regular, small intervals (such as 0.1 miles in the US).

Applies to

  • Trail markers
  • Road markers
  • Railroad features
  • (incomplete list, please expand)



  • distance=23.2
  • distance_marker=47


After giving it a bit of thought, should this tag be under Properties? I would like to see it used with a specific icon so they show on the map.


  • It would be useful to just be able to say "distance_marker=yes" if you saw the marker when surveying but were unable to read the text. Or perhaps, if the text is now illegible. Gerv 16:56, 3 February 2008 (UTC)
