I have just started to put some things on the Open Street Map. In my town, a few shops were put there on the open street map, but they are now gone and vacant. It is the retail in this place - Way History: 28140595 | OpenStreetMap
There are a lot of shops vacant in the UK, so it would be very interesting if people could see what was happening in their town.0 With the tag, there is a percentage of the total amount of vacant. What I would like to do is to publish a percentage of vacancies within a specific place. So, for example, people see that in this street, where you go to the shops, 20% of them are vacant. Then, people can look again at this map a few months later when these tags have gotten up or down for the last week, for example.
I was wondering if there was a way I could create this and if people could help me figure out how to do it!
I don’t know how widely recognised it is, but shop=vacant has over 7,000 uses in the UK (over a wide area based on overpass-turbo results), so you might be able to do something with the proportion of shop=vacant tags compared to all shop tags in a given area.
There’s a slight difference in meaning between shop=vacant and disused:shop=*, and both can be used in combination:
shop=vacant means the storefront is currently vacant.
disused:shop=* means whatever used to be in the storefront is no longer there, but whether the storefront is currently vacant is less clear.
Around me, many storefronts are built years before the first shop occupies them. The shop is no longer under construction; it remains vacant but has not fallen into disuse. shop=vacant is the only tag that can be used in this situation.
When a shop moves from one neighborhood to another, I immediately retag the former location as disused:shop=*, but I don’t feel confident tagging it as shop=vacant until I’ve surveyed the site to make sure some other shop hasn’t moved in already.
Often a disused:shop=* lingers even after a new shop arrives and is tagged in shop=*. Technically, was:shop=* would be more precise for this situation.
For a quick visualisation, I would go to Overpass Turbo and look for all objects with addr:street=High Street or whatever the street name is, and an amenity= or shop= tag that isn’t shop=vacant.
Then look for all objects that have addr:street=High Street and either disused:amenity=, disused:shop= or shop=vacant.
You can use MapCSS to style the results e.g. make the nodes for active shops blue and the vacant ones red.
If you want to do this for all of Newbury Wharf (the landuse=retail area), instead of just one street, you’ll have to use a spatial query. I am sure this is possible with Overpass though I don’t know how.
Unused can definitely mean “never been used before (still new)”, and disused can definitely mean “no longer in use (previously used)”. In these two contexts they are not synonyms. But both words can also mean “not currently in use”. In this case they are synonyms. English is a crazy language .
Exactly, which is why I think tagging never-before-used features as disused is misleading and too literal a reading of the disused wiki page. After all, it says “no longer” half a dozen times, just to hammer home the point.
Given that any mapper using shop=vacant at all is breaking the definition of shop=* (“A place selling retail products or services”), I see no reason to assume that they would consistently follow such a subtle distinction.
To you, a newly constructed shop is nothing currently (no main tag), but some time ago (probably while it was under construction) it was fully functional and operational shop (disused:shop=yes, which would’ve been shop=yes at that time). Is that correct?
