Problematic tag

This tag is a bad idea - not mapping this kind of thing in general but tagging it using the waterway=* key. The concept of normal waterways (river/stream/canal etc.) is completely orthogonal to that of a fairway. Many navigable rivers have a route marked with buoys - in that case the mapper would need to decide if to tag it waterway=river or waterway=fairway or to create two ways - does not make much sense. Better to use a different key. --Imagico (talk) 22:23, 21 July 2016 (UTC)

If you have a proposal to use a different tag? This is explicitly not meant to replace waterway=river or waterway=canal (which IMHO are clearly defined), but to making routing possible on lakes and seas where there is a) no clear routing (looking at OSM data) and b) a defined route for boats. --Mdeen (talk) 06:00, 22 July 2016 (UTC)
OK - we have three different concepts here:
  • The waterway as a physical hydrographic feature, a river or a tidal channel for example.
  • The route regularly taken by ships/boats, which is usually mapped as route=ferry.
  • The buoys marking the channel.
What we are talking about is the last point - ideally this should be mapped as individual buoys but of course a simplified mapping like this route is marked with buoys on both sides should be possible. I have no specific suggestion how to tag this but it should not be difficult to come up with an intuitively understandable concept. --Imagico (talk) 07:53, 22 July 2016 (UTC)
I second the comments here, waterway=fairway isn't a good value. Mapping individual buoys as seamark=* and use route=* sounds better. Fanfouer (talk) 21:54, 27 March 2018 (UTC)

We have already a tag for this
