Then I see 2 possibilities for the old roofed area that could make sense:
* leisure=pitch + sport=equestrian + covered=yes
* building=riding_hall
See building=riding_hall

Hi, why did you tag way/1090555830 with leisure=horse_riding and way/1090555831 with leisure=pitch + sport=equestrian ? In Bing way/1090555830 looks like a jumping arena. If this is true it should also be tagged with leisure=pitch + sport=equestrian, see leisure=pitch#Riding_arena. Tag leisure=horse_riding could rather be used for the area of the whole Club Hípico, but this is already tagged as park. Furthermore, way/1090555832 seems to be quite small for sport=horse_racing, but I don't know what that is.

If way/1090536661 is a https://en.wikipedia.org/wiki/Round_pen the usual OSM tagging would be like for riding arenas, see leisure=pitch#Riding_arena.

Hi, you have removed building=stable from way/871818122 and replaced it with leisure=horse_riding. I am not sure if this was intended because this object looks like a building in bing. Also the horse_riding tag seems inappropriate for such a small area, it is for the whole area of the ranch (see leisure=horse_ridin), so the area tagged with leisure=horse_ridng should probably at least also contain the stable way/1090822981 (or set a node). For riding arenas see leisure=pitch#Riding_arena.

Hi, you have removed the building tag from way/31898888 and replaced it with leisure=horse_riding. This object looks like a building in the aerial view, therefore I assume it was not intended to remove the building tag. Furthwemore, the horse_riding tag is for the whole area of the facility and not for just one building, see leisure=horse_riding. If this building is a riding hall / indoor arena consider using tag building=riding_hall instead.

It is ok then and dosn't need to be changed. If in iD you search for "riding ring" you get the preset with name "Horseback Riding Arena" which adds the tags leisure=pitch + sport=equestrian.

I'm not sure I understand this completely. Don't you think this area should be called "arena"? Compare https://www.arenas.ebarrelracing.com/ohio/wb-ranch-and-arena-swanton-oh/

last link fixed: osm.org/query?#map=17/40.73315/-77.93085

and osm.org/query?map=17/40.73315/-77.93085

The difference between leisure=pitch + sport=equestrian and leisure=horse_riding is not that one is for practice or warn up and the other for competition. The difference is that leisure=pitch + sport=equestrian is for just the riding areas and leisure=horse_riding is for the whole facility including stables and other stuff, see leisure=horse_riding and way/916315775

Erledigt, s. changeset/125586936

Thanks, I also corrected these old ones: changeset/125563663

Hi, du hast hier building=shed durch leisure=horse_riding ersetzt. Auf dem Luftbild sieht es aber so aus, als ob das Gebäude noch da ist. Wenn das so ist, wäre ein building-Tag nach wie vor sinnvoll. (Gilt auch für way/80338466).
Außerdem ist leisure=horse_riding auch nicht für einzelne Gebäude geeignet, sondern für komplette Reitanlagen (siehe osm.wiki/DE:Tag:leisure=horse_riding). In diesem Fall hier würde es wahrscheinlich an way/111499967 gehören. In der rechten unteren Ecke davon kann man auf dem Luftbild ja die Reitplätze erkennen (osm.wiki/DE:Tag:leisure=pitch#Reitplatz).

Hi, I think way/1065076254 looks like a riding arena (see leisure=pitch#Riding_arena) in the aerial view, but you have tagged it with leisure=horse_riding, which is for complete riding centres (see leisure=horse_riding).

It seems the site "Old Spanish Trail Arena" is an area much larger than just this building, see
* https://barrelhorseworld.com/Details/902/Old-Spanish-Trail-Arena
* https://grandcountyutah.net/179/Old-Spanish-Trail-Arena
So the leisure tag (stadium? horse_riding? sports_centre? ...?) would probably go for the whole area and the building tag just for the indoor arena (building) inside that larger area.

landuse=equestrian on way/1088814411 is not a defined tag, maybe leisure=pitch instead would fit better, see wiki.openstreetmap.org/wiki/Tag:leisure=pitch#Riding_arena

I don't know this building. You wrote that the area is covered, so maybe building=roof would be more specific? Otherwise, perhaps building=stadium or building=riding_hall? If nothing more specific fits, building=yes.

On a map that only shows buildings (regardless of their use) buildings without a building tag will not be shown.
Of course, nobody forces you to map the building(s) in a stadium; but in this case it was already tagged as a (quite large) building before, and you removed the tag, although it was not wrong. I thought that was unintended.
Compare indoor examples on wiki page for sports_centre:
leisure=sports_centre#Indoor. If you can find further evidence that a building tag is unnecessary in this case, please let me know; this is not the first time that I have seen mappers replace building tags with leisure tags.

I think that every building needs a building tag, regardless of whether it also has other tags or not. Otherwise it will not be rendered as a building.
On the wiki page it says "building=stadium : the building area (if applicable as a multipolygon)", I don't understand what that means. If you mean that this stadium building does not need a building tag, then so be it.

Hi, I think leisure=track + sport=horse_racing is inappropriate for way/1088856632. This is a jumping arena, it should better be tagged as leisure=pitch + sport=equestrian, see leisure=pitch#Riding_arena. The obstacles / fences in this jumping arena are not permanent and should therefore better not be mapped, see barrier=horse_jump.
