inconsistency rendering direction arrows for waterways

Reported by: skyper Owned by: team
Priority: normal Milestone: 16.02
Component: Internal mappaint style Version: latest
Keywords: waterway direction arrow Cc:


There is at least an inconsistency in rendering direction arrows for waterway=*:

  • while canal is rendered with arrows (upper)
  • ditch is rendered without arrows (lower)


Please turn it around and do not render arrows for canals as they may have been tagged with oneway=*, too.

Recently there was a dicussion proposing a new tag flow_direction=forward/backward/both/none for man_mad=pipeline and waterway=* as oneway=* is an access condition.

This somehow reminds my about the discussion about rendering incline=*.

  • wadi usually have a flow direction and it would be consistent to render arrows

comment:2 Changed 4 years ago by skyper

This is inconsistent compared to validator, which warns about changing direction of any waterway=*.

In 9538/josm:

see #10290 - Consider waterway=canal as not directional, waterway=ditch|wadi as directional

Resolution: fixed
Status: newclosed

In 9539/josm:

fix #10290 - Improve ReverseWayNoTagCorrector

It evaluates its own directional tags together with those defined at
OsmPrimitive#directionKeys minus the ones that can be corrected using

I think wadi was obsoleted (on wiki and in JOSM) so probably adding rules for it (outside of validator) is not much gain. Or what is the policy in these situations?

Yes, wadi has a validator warning and no line style. It should therefore not have direction arrows.

comment:8 Changed 4 years ago by Klumbumbus

Resolution: fixed
Status: reopenedclosed

In 9552/josm:

fix #10290 - remove wadi direction arrows; see #12404 - improve fence_type=chain validator warning message
