Used for a distance marker along a waterway. The signs/markers with the river kilometres can be found left or right on the shore.

How to map

For the pole/board/marker stone on the shore

Draw a node and add the following:

• waterway=milestone
• distance=* or river:waterway_distance=* – specified distance (in km); distance=* is used much more frequently (approx. 10:1)

Optional seamark tags:

• seamark:distance_mark:category=pole/board/unknown_shape
• seamark:type=distance_mark – OpenSeaMap/Distance_Marks
• seamark:distance_mark:distance=number
• seamark:distance_mark:units=kilometres/hectometres

For the virtual kilometre point in the river

Place a point directly on the way that represents the waterway and add the following:

• waterway=milestone
• distance=* or river:waterway_distance=* – distance (in km); distance=* is used much more frequently (approx. 10:1)

Optional seamark tags:

• seamark:distance_mark:category=not_installed – virtual river kilometre
• seamark:type=distance_mark – OpenSeaMap/Distance_Marks
• seamark:distance_mark:distance=number
• seamark:distance_mark:units=kilometres

Rendering on OpenSeaMap

• Rheinkilometer 364

The black circles are the milestones or the hectometre stone (hm1), the coloured circles are the virtual kilometre points.
