Re: [Talk-GB] Tagging showgrounds

[Ian Caldwell via Talk-GB]

As a local, I think it should be tagged as commercial. There is some event
there most weeks. It's a very commercial organisation.

Re: [Talk-GB] Showgrounds (tagging)

[Ian Caldwell via Talk-GB]

For the  Three Counties Showground in Malvern
https://www.openstreetmap.org/way/35432806 is tagged with
landuse=commercial. Any given the number of events there most of which are
commercial. Commercial would be correct. That how the NEC is mapped

Re: [Talk-GB] Farmland (crop or animals)?

[Ian Caldwell via Talk-GB]

I have tagged as meadow when I believe the land is not ploughed.

Given crop rotation tagging farmland with crop= or animal=  is problematic
unless that tags are updated at least annually.

One farmer I used to know is crop rotations was barley for a year or two.
Then a grass ley for two or three years, which he both silaged and grazed
his cows on. Then he had a crop of sweet corn , which he silaged for cow
feed. In the year he rotated from grass to sweet corn he would try and get
one silage crop of the land before he planted the sweet corn.

Re: [Talk-GB] Common Land has stopped rendering

[Ian Caldwell via Talk-GB]

For now, for the commons around Malvern I will add landuse,  In most cases
landuse=meadow.
