Morning all,
Someone has commented on a change I made to the Three Counties
showground last year when I changed the tagging to landuse=grass rather
than landuse=commercial. Their suggestion is that it really ought to be
landuse=recreation_ground, with a secondary tag of surface=grass.

I've responded to that comment on the changeset, but I thought it would
be worth throwing out here as well.
I do think that tagging showgrounds as landuse=commercial is generally
incorrect; it doesn't match the description of 'commercial' in the wiki
and doesn't reflect the typical uses of showgrounds both when a show is
on and when one isn't.
The reason I tagged the Three Counties showground as grass is because,
most of the year, that's precisely what it is - an open area of
grassland. Unless there is an event on (which only happens for a
minority of days in a year) it is just an open space.
Looking at a few other showgrounds across the country, we don't seem to
have any consistency.
The East of England Showground is tagged as landuse=recreation_ground:

The Suffolk Showground is tagged as a park:

So is the Staffordshire County Showgound:
https://www.openstreetmap.org/#map=16/52.8255/-2.0643
The former Royal Showground at Stoneleigh is tagged as commercial, but
in that case that's probably now correct as it's no longer used as a
showground and is gradually being redeveloped as a business park:
https://www.openstreetmap.org/#map=15/52.3435/-1.5220
The Great Yorkshire Showground isn't tagged as an area at all, just a
network of roads and individual features:
https://www.openstreetmap.org/#map=16/53.9830/-1.5065
Similarly with the Norfolk Showground
https://www.openstreetmap.org/#map=16/52.6490/1.1793
And the Bath and West Showground:
https://www.openstreetmap.org/#map=16/51.1552/-2.5265
So, what do people think? Personally, I think that showgrounds ought to
be tagged as an area, because they do, typically, have clear boundaries
and are distinct from their surrounding context. But I'm less sure what
the area should be tagged as. I think commercial is usually wrong, for
the reasons I've already given, but I can see an argument for either
grass, recreation_ground or even park.
Thoughts, anyone?
Mark
