Any suggestions? Leave it be? Seriously: You've got the tagging right, so there's no need to change that. You could request a change in the main Mapnik renderer, but the problem with that is that elsewhere on the map the colouring is correct, and changing it will probably have adverse effects. If you can find/draw a small football graphic that could be used as a background in the Mapnik render (see nature reserves/cemetaries for how it looks), but I don't think the colour should change, and even with the graphic the pitch may not be obvious. On a more philosophical note, if the only difference between the pitch and the surrounding common is that it's kept mown, there actually *isn't* any real difference between the two. Should the man with the mower stop, nature will reclaim the pitch very quickly. Is the pitch really permanent?

It's correctly tagged, a In both these cases (and frankly in general) having it rendered would an advantage, and I can't really think of a disadvantage (orther than hastle in getting it done) The original post complained about the colour of a football pitch being the same as the surrounding common, and hence not distinct. My objection was to changing the rendered colour of pitches for this one example, since elsewhere on the map people would expect to see either of those things in green. I did suggest a background with a football icon as a way of distinguishing the two, but I think it won't particularly help, since you'd have to be at quite a high zoom for this to show up. I don't think there's *any* change we could make to rendering that would make a football pitch stand out at low zoom. From the example we're discussing (http://osm.org/go/euwjlzeC--), I think z15 is the lowest where it would stand out, and that's far enough in that you'd have to know it was there anyway. As I said, I think this is a job for search, and the data is fine for that. other points being: we have the data, why isn't it getting rendered; while perminence is an argument of sorts, that's what updating the map is for, (a housing estate can become brownfield site with the aid of a bulldoser) The permanence thing was, as I said, more of a philosophical discussion. So while i understand your point to some extent, I do think it's worth doing somthing about, even if it's not a huge priority I don't think there's a need to do anything with the data -- that's correct as is, and if someone uses a search tool to find football pitches in OSM, it'll show up. Rendering? Happy to see some change, but not just for this one example at the expense of all others. -- Jonathan (Jonobennett) ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

Any suggestions? A pitch is rendered a different shade of a green to a common (in Mapnik). Its just that tile hadn't been rerendered yet. I have noticed some delays in Mapnik rendering over the last few days. I've marked that tile as dirty, and its now been rendered, so the pitch now shows up clearly: http://www.openstreetmap.org/?lat=52.09667lon=-2.32785zoom=17layers=B000FTFT Craig ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
