LOL. Unfortunately many people make this mistake, it is also not so well done in the iD editor that you don't get a warning. See https://github.com/openstreetmap/id-tagging-schema/issues/1404

Hi,
You have retagged way/1210428367 from building=yes to leisure=horse_riding. But this object seems to be a building and is too small for a horse riding centre. Every building should have a building=* tag, otherwise it is not renderd as a building. The tag leisure=horse_riding is not for buildings, it is for complete riding centres (which may cointain some buildings, arenas and other things). Compare OSM wiki.
Good examples:
way/494425529#map=18/46.118112/14.575688&layers=P
node/12184697658#map=19/46.170882/14.606235&layers=P

Hi,
way/1301634980 is not horse diding centre (leisure=horse_riding), it is a horse riding arena and should be tagged leisure=pitch + sport=equestrian, like way/1008770819

Hi,
way/1353480679 seems to be a building. In OSM every building should have a building=* tag (otherwiese it will not be rendered as a building). The tag leisure=horse_riding is not for buildings; it is for complete horse riding centres. Here is an example how you can map a ranch:
way/310921211
See also:
leisure=horse_riding

Traducción:

Hola,
way/1353480679 parece ser un edificio. En OSM cada edificio debe tener una etiqueta building=* (de lo contrario no se mostrará como un edificio). La etiqueta leisure=horse_riding no es para edificios; es para centros ecuestres completos. Aquí hay un ejemplo de cómo se puede mapear un rancho:
way/310921211

Dziękuję

Hi,
Please do not retag buildings as riding centres as you have done here:
way/400191590/history
way/400191631/history

Buildings always need a building=* tag, otherwise they will not be displayed as buildings on the maps.
Indoor arenas can be tagged building=riding_hall, horse stables can be tagged building=stable and so on, see OSM wiki.

Hi,
You have retagged way/175709721 from building=yes to leisure=horse_riding, so that now it is no lomger rendered like a building. But itt seems to be a building. So this was probably a mistake.
The tag leisure=horse_riding is not for buildings, it is for complete horse riding centres (which may contain buildings and other things). Here are examples:
way/463898774
node/6400515149

Bonjour,
Vous avez fait passer way/175709721 de building=yes à leisure=horse_riding, de sorte qu'il n'est plus rendu comme un bâtiment. Mais il semble que ce soit un bâtiment. Il s'agissait donc probablement d'une erreur.
La balise leisure=horse_riding ne concerne pas les bâtiments, mais les centres équestres complets (qui peuvent contenir des bâtiments et d'autres choses). Voici quelques exemples :
way/463898774
node/6400515149

Ach ja, das Gebäude war ja schon richtig mit building=yes getaggt, da habe ich wohl was verwechselt und unnötig gemeckert.

Hi,
was du hier als Reitanlagen gemappt hast, sind keine Reitanlagen im Sinne von osm.wiki/DE:Tag:leisure=horse_riding.

way/1349631811 ist ein Reitplatz und sollte mit leisure=pitch + sport=eqzestrian getaggt werden.

way/1349631812 sieht aus wie Gebäude. Keine Ahnung, was für eins. Es gibt verschiedene Gebäude-Tags, z.B. building=stable, building=shed, building=riding_hall etc., notfalls building=yes.

Was way/1349631813 ist weiß ich nicht. FÜr einen Reitplatz ist es etwas klein (20 x 20m) aber vielleicht ist es doch einer; oder ein paar Paddocks, dann siehe osm.wiki/DE:Tag:landuse=animal_keeping

Das Reitanlagen-Tag leisure=horse_riding kann man an dem Graf-Raisach-Hof (way/722431433) ergänzen.

Hi,
carrières équestres like
way/1349220878 should be tagged differently, like this one: way/1244652067

Hi,
way/1349737074 ist keine Reitanlage, das ist ein Reitplatz, so wie way/1237290374

Hi,
way/1349199789 ist keine Reitanlage (Tag leisure=horse_riding) sondern ein Reitplatz. Reitplätze werden in OSM üblicherweise mit leisure=pitch + sport=equestrian getaggt, hier z.B.: way/263138004 (dieser Reitplatz befindet sich innerhalb way/220383748). Vgl. osm.wiki/DE:How_to_map_a/R#Reitstall

Hi,
You have retagged the buildings way/291647969 and way/291648351 to leisure=horse_riding (horse riding centres). Therefore they are no longer rendered like buildings. This was probably not intended. All buildings should have a building=* tag. If these buildings are indoor arenas you can tag them building=riding_hall INSTEAD OF leisure=horse_riding. The tag leisure=horse_riding is not for buildings, it is for complete riding centres (node/2951129540 is ok).

In JOSM you can tag a riding arena with the preset for sport=equestrian.
