You're right, a riding arena is not a pitch, but in the early days of OSM someone started tagging them that way, it spread and after a while so many were tagged that way that it can't be changed any more. Have a look at leisure=pitch#Examples !

Hi,
Not so bad, Some things you could improve:
- Outdoor arenas are usually tagged leisure=pitch + sport=equestrian (iD preset "Horseback Riding / Rodeo Arena")
- Indoor arenas can be tagged building=riding_hall (there is no iD preset yet, will be in next release)
- Horse exercisers can be tagged animal=horse_walker (there is no iD preset yet)

Wiki:
- building=riding_hall
- animal=horse_walker
Examples:
- way/1008067851
- way/1230004271

Hi,
I think the riding hall should not get the horse_riding tag because this tag is for the whole area of the rideclub, see leisure=horse_riding#When_not_to_use
If you want to put a leisure tag on the riding hall then better use leisure=sports_hall, see building=riding_hall#Use_as_a_riding_hall This would avoid nested leisure=horse_riding tags.

I have no special qualifications to answer these questions, but here are my thoughts:

Polo fields

It seems that most of them (386) are tagged leisure=pitch + sport=polo. I think it makes some sense because I would not call a polo field a riding arena. OTOH round pens are usually tagged like riding arenas nevertheless and there seems to be (see wikipedia) also "arena polo" which is played in smaller polo arenas. A seperate sport=* tag for every equestrian activity is perhaps not such good idea. Therefore I do not want to give a recommendation how to tag polo fields. Maybe you want to ask about that in the community forum. Compare old wiki discussion osm.wiki/Talk:Tag:sport%3Dequestrian#Subtags_for_Dressage_and_Jumping_Arenas

Therapeutic riding

I am not aware that any therapeutic riding center tag exists.
https://overpass-turbo.eu/s/1ExV finds some riding centres for therapeutic riding that are already mapped.
I can imagine that a new (sub)tag for therapeutic riding could be invented with key healthcare:speciality=* which could then be used in combination with leisure=horse_riding or with some other main tag. But I am not familiar with the tagging of healtcare facilities, so maybe better ask about that in the community forum. If you want to invent/propose new tags, see osm.wiki/Any_tags_you_like and osm.wiki/Proposal_process for a number of things to consider.

Hi,
way/1229919288 ist keine Reitanlage, das ist eine Führanlage, siehe osm.wiki/DE:Tag:animal=horse_walker . Ich habe noch nie jemanden in einer Führanlage reiten sehen.

Sorry for the late response. Yes, looks good now.

Hi,
These small round pens like way/1229562954 are no riding centres (leisure=horse_riding); they should better be tagged leisure=pitch + sport=equestrian. See
osm.wiki/Tag%3Aleisure%3Dhorse_riding and compare way/1185163885/history

To find the preset for tagging riding arenas in JOSM search for "equestrian" or use the link at the bottom of the horse_riding preset.

Preparing answer ...

Hi,
Here you have a) re-tagged a riding arena to a riding center and b) tagged an indoor riding arena as another riding center. I think the previous tagging was perfectly fine. You have re-tagged some other riding arenas in a similar way (e.g. way/1228970021/history). I find that weird and am curious to know why you did that.

Web page https://www.pizazzfarm.com/facility-rentals says that the farm contains an indoor arena and an outdoor arena. Wiki page osm.wiki/Tag%3Aleisure%3Dhorse_riding says "Use this tag only once for the whole facility, don't use it multiple times on different objects belonging to it (one feature, one OSM element rule ...)". Otherwise there will be more than one riding center on the map where in reality there is just one! Therefore I would not add this tag to the arenas but instead create a new object (area or node) for the whole farm and tag that with leisure=horse_riding. Example: way/842259858

Hi,
I see that this was only your 2nd changeset.
The area you re-tagged was previously tagged as a building, and I assume that building is still there. But the iD editor has removed the building tag because you re-tagged it as a riding center. Now it no longer shows up as a building on the map because there is no longer a building=* tag.
I also assume that Paddock Paradise consists of more than just this building.
I therefore suggest to add the building tag again and for the whole Paddock Paradise better create a new object (area or node) . Compare
osm.wiki/Tag%3Aleisure%3Dhorse_riding
way/957096647 (good area example)
node/6140383631 (node example)

This area looks like a riding arena and not like a riding centre. The same is true for way/1229253932. Riding arenas should be tagged leisure=pitch + sport=equestrian. Compare previous discussions:
changeset/144783334
and
changeset/144858341

Hi,
way/1229251266 is a riding arena and not a riding centre, riding arenas should be tagged leisure=pitch + sport=equestrian

way/1229251265 : a horse walker is not a riding centre either; I have never seen anyone ride in a horse walker. Tagging see wiki page.

Thanks for the improvements. (An appropriate undocumented tag is better than an inappropriate documented tag, IMHO).

As far as the riding arenas are concerned, this preset is absolutely not impossible to find. If in iD you search for just "horse", the preset "Horseback Riding / Rodeo Arena" is listed after "Horseshoes Pit", "Horse Racetrack" and "Horse Race Course". This is iD without AI, it cannot read your mind what you want to map. So if you want to map a riding arena I would recommend to search for "riding arena", then the corresponding preset is listed at the top of the list.

For horse walkers there is no preset yet, you have to search in the wiki and type it in; compare https://github.com/openstreetmap/id-tagging-schema/issues/835

Thanks for your PN. I have tried to correct the tagging. Please check it.

Hi,
way/1228803041 is not a riding_centre (leisure=horse_riding), it is a riding arena. Riding arenas are usually tagged leisure=pitch + sport=equestrian and there is a separate preset in iD that does that. Compare leisure=horse_riding

way/1228803042 is not a riding_centre (leisure=horse_riding) either, it is a horse walker, like in older discussion changeset/129900838#map=16/50.8452/4.5144

Hi,
Please tag riding arenas differently from riding centres.
way/1228495467
way/1228495468
way/1228495469
are riding arenas and should be tagged leisure=pitch + sport=equestrian (the last one is not really an arena but just round pen, but they are usually also tagged like arenas). iD has a separate preset for riding arenas.

node/11392666605 is for the whole riding centre. This is ok, but there should be only one object (node or way) tagged with leisure=horse_riding for every riding centre.

Oops, hadn't seen that this is in Belgium. So here is the English translation:

Hi,
way/1004981814 is not a riding facility. It's a horse walker, see animal=horse_walker . I have never seen anyone ride in a horse walker.

Hi,

Hi,
die Flächen, die du hier mit leisure=horse_riding getaggt hast, sind keine centres équestres. way/1227350454 ist vermutlich ein Reitplatz, der a
dann mit leisure=pitch + sport=equestrian zu taggen wäre (was du ja in ähnlichen Fällen bisher auch gemacht hast). way/1227350452 und way/1227350453 könnten Flächen für die Haltung von Pferden sein (Paddocks, landuse=animal_keeping).

Hi,
way/1227005185 looks like a riding arena. Riding arenas are usually tagged leisure=pitch + sport=equestrian and there is a preset in iD for riding arenas that does that.
You have tagged this area leisure=horse_riding which is for complete riding centres.
Please compare the following example and wiki page:
