Canal indicates a form of construction - man-made. Unlike natural watercourses they were constructed because someone had a purpose in mind, which might have been anything... Transport (using boats/barges), moving water about, decoration, powering watermills, providing a relief route to a river, improving the navigability of a river...___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

Per the wiki "Use waterway=canal for man-made open flow (free flow vs pipe flow) waterways used to carry useful water for transportation, hydro-power generation OR irrigation purposes." E.g. there are a range of purposes for which waterway=canal is used. The access tags could be used to make it clear - access=no and/or boat=no. --- https://hdyc.neis-one.org/?spiregrain spiregrain_...@ksglp.org.uk On Thu, 14 Nov 2019, at 12:22 PM, Martin Wynne wrote: > "Canal" should surely be restricted to transport functions?

Re: [Talk-GB] Tagging Mill Races / Leats / Lades
I pieced it together as best I could and came up with that, which reminds me that we need much better (UK-specific) tagging information on the Wiki. Nothing stopping anyone rolling their own tags though. I'd have gone for man_made=leat which has some small precedent.

Re: [Talk-GB] Tagging Mill Races / Leats / Lades
I think instead of canal=headrace you meant to write usage=headrace? That's what's in the wiki, and also 1000+ entries seen in taginfo. I've chatted many times to people about millraces, but the term "headrace" (and "tailrace") is new to me. I'll add keywords to the wiki to make searching easier.

Re: [Talk-GB] Tagging Mill Races / Leats / Lades
"Canal" should surely be restricted to transport functions? Boating apps presumably treat "canal" as a route unless navigation restrictions are added. If the stuff that is moving is the water rather than the boats, "aqueduct" would be the correct term. cheers, Martin. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] Tagging Mill Races / Leats / Lades
Looking at the existing guidelines it would be waterway=canal and canal=headrace (canal here used in the power rather than transport context) If this is indeed correct then it's not very obvious but it is detailed here: https://wiki.openstreetmap.org/wiki/Proposed_features/Hydropower_water_supplies#Headraces Regards, *Paul* On Thu, 14 Nov 2019 at 11:16, Charlie Reid wrote: > Hi > > > > Can find no guidance on the Wiki about tagging mill races.

[Talk-GB] Tagging Mill Races / Leats / Lades
Hi Can find no guidance on the Wiki about tagging mill races. I come across these continually while surveying. They are a totally distinctive water feature which don't bear much relation to listed waterway types. Drain seems to be the closes value - but this really misrepresents their appearance, purpose and behaviour.
