I’ll have a go at asking. I’ll see if I can ask for re-use of the actual GeoJSON query response and data found on that web page/overlayed map data on that page.
Clicking on the marker seems to give the addresses of the fountains, I imagine it’s unlikely we will add tags for that but I’ll see if I can get clarification whether it’s third party licensed or not.
EDIT: Says it contains OS data, so I imagine the addresses are from OS.
I’m also curious to know how accurate these coordinates are since that would give an indication whether there can be a “straight” import.
It’s useful information, but not as good as having the accurate opening_hours explicitly tagged, since data users won’t be able to automatically determine if it’s open or not.
(Moreover in the specific example you gave, it’s not completely obvious which of the opening times should apply to the toilets. Are they associated with the box office or the cafe?)
For the particular example, the toilets would be open when the centre is open, which depends on events booked. So no fixed hours. Not really associated directly with box office or cafe/bar which may be open too.
Robert pointed me here. I built https://papamap.de, a map of every changing_table=yes in OSM for eleven countries, UK included, coloured by changing_table:location. Green if a dad can reach the table (men’s, unisex or a separate room), red if it’s in the women’s only, grey if nobody has recorded the room yet.
For the UK that’s 2,520 grey out of 2,692. So if you’re surveying toilets for the project anyway, changing_table:location is one more tag worth a look, it takes under a minute on site. Every grey pin links a MapComplete question that asks exactly that.
In theory yes, but I’m not sure doing something custom for one small dataset would be worthwhile, particularly as it’s rather out of date. It might be better just to compare the lists manually. If there were any toilets tagged with operator= Hounslow London Borough Council, then you’d be able to see a list at OSM UK Toilets Operator Report .
I’m not sure brand is really the right thing, unless there’s specific branding/signage used at each location. But they could be tagged with access=yes rather than access=customers. It would be good to have some (ideally machine-readable) way to tag that they’re part of a community toilet scheme though to explain the unusual tagging for toilets inside a shop/cafe.
Got a reply from the Greater London Authority (GLA) about water fountain data and apparently the data comes from Thames Water rather than GLA direct (as it was done in partnership with them), so now we’re awaiting a response from them.
Over the quarter the number of amenity=toilets objects increased by over 350, compared with the historical trend of about 175 per quarter. We’ve also seen small increases in the percentage of toilets with various other useful tags added, and the median age-since-last-edit on amenity=toilets objects has dropped by about 6 months.
