Re: [Talk-GB] Changing highway=ford to ford=yes.
I'd say the analogue to a ford is a level crossing: two ways of different types, usually vertically separated but instead intersecting at the same level, notionally at a point (though you could define an area if you want that level of detail). Coincidentally, some fords local to me (one which remains elusive and not mapped) are on my radar. I'll wait for a consensus to emerge here before seeking them out for mapping.

I spent a bit of time looking at how people mapped fords when I updated the rendering on https://map.atownsend.org.uk/maps/map/map.html to support fords mapped as ways. There were examples were people had mapped the way perpendicular to the water (e.g. https://map.atownsend.org.uk/maps/map/map.html#zoom=21=52.6509984=-1.2567927 ) and also "long fords" where the two are one and the same (e.g. https://map.atownsend.org.uk/maps/map/map.html#zoom=20=53.1373688=-1.468014 ). I didn't find much (any?) area usage. Both types of mapping are pretty logical, though, as is "just add it as a node at the intersection".

To me the issue is one of consistency - it feels a bit odd to map one feature in detail if features around it aren't similarly mapped. OTOH when adding detail you have to stop somewhere. So on second thoughts go ahead - it's great that you're doing this. Just bear in mind that it's better to map something - even if it's just a node ford with no width, length or depth - than nothing at all. Well you can't detail everything in one go, you have to start somewhere. I try to go back to the map and add as much detail as I can from time to time, from photos, notes, etc. If you just want something - anything will do, I don't see the point in bothering. There are plenty of other maps with that -- Google, Bing, OS. The whole point of OSM is that you can build up a proper detailed record of an area, and each mapper can add their own expertise.

Perhaps to canoes and hovercraft... There are quite a few highways that have streams of water running along them, used by walkers, bike riders as well as motor vehicles. This is where ford=yes as a way is appropriate, as indicated on the wiki. In any case the point where the highway intersects the thalweg should be tagged with something to indicate that it is not in error. That is, where a highway and a river cross there should either be a node tagged as a ford, or either the river or the highway should be tagged as bridge or tunnel (and there should be no node at the intersection). With regard to the automated edit, I'd like to know: - does this fix or solve anything (ie for data consumers), or is it just to make data consistent? Both. The 'standard' map doesn't render highway=ford. Constancy avoids confusion, making things easier to comprehend, & reduces errors. - what are you doing to nodes that have both highway=ford and ford=*? removing highway=ford, as they're all nodes. - what are you going to do to prevent more highway=ford nodes being created in future? Nothing, other than what's already in place. I've not checked all editors but highway=ford default was removed from Potlatch & never included in iD (I believe). JOSM flags it as a 'deprecated tag' error message on upload. And wiki is clear. However, contributors (especially newbies) copy tags they see others have already added, assuming it's correct practice. Removing abandoned tags will greatly reduce the likelihood of them returning.

Treating a ford as a single node strikes me as a bit daft when if you zoom in on the map it clearly occupies a mappable area between the various property boundaries and the entry and exit points on the highway. We are instructed to "map what we see", and the fords in this area are definitely bigger than a single point such as a lamp-post or postbox.
