leisure=stadium is about a place where you watch events and should have a substantial sitting places for spectators.
Both in Estonian and Russian school’s football field with a running track is often referred to as “kooli staadion”, “школьный стадион”, this leads to confusion and many map it as leisure=stadium. But schools usually don’t offer a lot of places for spectators. leisure=stadium is something built specifically to watch events.
A. Le Coq Arena is a good example of leisure=stadium. Though in Estonian scale I’d say that even a pitch with bleachers for 300 people could be considered a stadium.
So, how to tag them then? OSM doesn’t have an exact tag for this kind of thing.
- If you don’t need a name, you can just map all of the sports offered by a “school stadium” (soccer field, running track, shot put pitch and long jump track) and not have a single enveloping feature.
But if you want to name it, it gets complicated - If it includes many pitches and is publicly accessible, usually in villages, you may consider landuse=recreation_ground with a name
- You can nest pitches. Have a pitch for a soccer field, have a running track and draw another leisure=pitch with sport=athletics;soccer around it all.
- Put a name on a soccer field without drawing an enveloping feature
I’ve already converted many stadiums this way to something else while updating schools around Estonia.
If someone else has some other Estonia-specific caveats or best-practices, please share!
