OpenStreetMap
At tonight’s Vancouver OpenStreetMap meetup we were wondering about the state of drinking fountains in Vancouver. The tag is amenity=drinking_water.
A search in Overpass Turbo tells us that in the rough boundaries of Vancouver 112 water fountains were mapped.
In the open data catalogue of the City of Vancouver 239 water fountains are listed. That means we have a coverage of less than 50 % of Vancouver’s drinking fountains in OSM. Errors in this assumption might include duplicates and outdated data in OSM as well as drinking fountains which are not operated by the city.

That tag is used on all sorts of objects .. wells, streams…
If you want to be specific you need a more specific tag, man_made=drinking_fountain.
If it is a tap man_made=water_tap.

The only solution is to use the Mapillary tag, as I did in Brussels and even in the whole of Flanders.

I have not seen the tag-value man_made=drinking_fountain before in Vancouver. With only 71 uses worldwide it does not seem to have a good adoption, however, I can see myself tagging drinking fountains with this additional info in the future.

I don’t see a reason. An amenity is a “nutsvoorziening” in dutch. I have ten man_made=water_tap in my house. “man_made” is always a bad tag key in my view as it is that or “natural”.
For the few wells that are not covered by “amenity”, you could specify that their water is drinkable. Well, even a the one well in my region becomes an amenity as the quality of water is controlled.
But all we are interested is is in free drinking water.

@philippec What did you mean by “The only solution is to use the Mapillary tag”? Is Mapillary an auto-miscorrected word?
