Name Conflicts

We shouldn't use track for that, because track is our main term for several kinds of ways in other context. I would prefer leisure=race_track to prevent misunderstanding. --Hurdygurdyman 08:04, 15 February 2011 (UTC)

Filled multipolygons vs centerlines

How should these be mapped? I'm seeing them mapped as multipolygon relations and simple centerlines. Personally, I think the multipolygons make these too complex, and the centerlines are more appropriate. Oddityoverseer (talk) 20:29, 4 June 2015 (UTC)

I've sometimes used this approach. --Stalfur (talk) 20:31, 4 June 2015 (UTC)
Yes, I like this. It's using a field, with a centerline for the track, and a polygon for the stadium. Oddityoverseer (talk) 20:41, 4 June 2015 (UTC)
If mapped as an area, it should not be the centerline anymore, it should be the outline of the track. My preference for the typical oval 400m-course is a multipolygon with two parallel lines (efficiently created in JOSM), leaving the 'inner' empty so it can hold the ballsport pitch and sometimes the smaller tracks/areas for jumping and throwing. example --Polarbear w (talk) 08:38, 5 June 2015 (UTC)
Why not the centerline? That's how we map most other linear features. I don't really care which way we do it. I'd just like a standard. Oddityoverseer (talk) 15:24, 5 June 2015 (UTC)
If you consider it an area, you would map the outline. If you consider it a linear feature - not mapping the area - you would use a centerline. But as many renderers default to area, outline works better for me.--Polarbear w (talk) 10:53, 6 June 2015 (UTC)
Also, I found an example of mapping the outline instead of the centerline here. Oddityoverseer (talk) 15:46, 5 June 2015 (UTC)
Another example would be this--geozeisig (talk) 05:42, 5 June 2015 (UTC)
