OpenStreetMap
All the countries in the World have their own Track & Field stadiums and tipically each track is represented in different ways in OSM. It can be hard when you download the data (if you have different domains, you cannot get all the tracks in one shot) or when you want to get an harmonized representation.
That’s why I invest my time to update all the Track & Field stadiums in Portugal, using the map provided by the Portuguese Athletics Federation.
In the first approach I just consider the right category and geometry.
Now I done something more detailed for the 7 tracks are being used now for the Portuguese Teams Championships. First I defined an inner line to get the name of the track in the map (using the label) and after I created an overall area with all the track and their tipical center (grass). Around I had defined the stands and the lights. Outside of the stadium I defined the streets, parks, trees, walking paths, etc.
It is my first structured approach in OSM. If anyone knows another experiences about Track & Field stadiums in OSM, please share with me.

Nice work, but please be careful with the tagging on the individual elements, and avoid duplications.
E.g., here, you’ve added essentially the same tags and name of the track to two different objects:
On this closed way, you added the leisure=track tag and name of the track, but it is actually only the inner of the track, not the track itself: way/182817080#map=19/37.02829/-7.91689
You then added this way as an inner of a multipolygon, setting again the leisure=track tag and the same name on the relation that is the actual track.
So now we have duplicate objects (or at least two with the same name and tag).
I would suggest to remove the leisure=track and name tags from the inner (possibly replacing leisure=pitch and sport=athletics), and only keep these tags on multipolygon.

Thank you, I will look the tags in the next update and verify if I keep the inner line.
