Hi,
you have removed building=yes from way/184714968 and replaced it by leisure=horse_riding + name=Les Ecuries de Lussat. And you have added node/13017140267 also with leisure=horse_riding + name=Les Ecuries de Lussat.
Now this Les Ecuries de Lussat is mapped twice and the building is no longer rendered as a building on the map. I propose to revert the tagging of the building; this will fix both issues.
Here is an example from not far away: node/12756686338#map=18/46.221376/2.212197&layers=P

Bonjour,
vous avez supprimé building=yes de way/184714968 et l'avez remplacé par leisure=horse_riding + name=Les Ecuries de Lussat. Et vous avez ajouté node/13017140267 également avec leisure=horse_riding + name=Les Ecuries de Lussat.
Maintenant, Les Ecuries de Lussat est cartographié deux fois et le bâtiment n'est plus rendu comme un bâtiment sur la carte. Je propose d'inverser le balisage du bâtiment, ce qui résoudra les deux problèmes.
Voici un exemple non loin de là : node/12756686338#map=18/46.221376/2.212197&layers=P

Ich habe es auf horse_riding geändert und sonst noch etwas ergänzt / verbessert so wie mir das nach Luftbild möglich erschien. Kannst es ja irgendwann kontrollieren / korrigieren.

Hi,
it looks like you have split one riding centre into four here:
way/1392097834
way/1415929062
way/1415929063
way/1415929064
I don't think this was a good idea. As explained on the wiki page for the leisure=horse_riding tag, this tag should be used for the entire riding centre once and not for all the objects that belong to it. What you have mapped now and tagged with leisure=horse_riding looks like riding arenas and round pens (https://www.jhrc.co.jp/images/gallery1.jpg) and should be tagged with leisure=pitch + sport=equestrian instead of leisure=horse_riding.

way/580524439#map=18/35.986371/139.617027&layers=P (example)

In JOSM you can use the preset for sport=equestrian to tag riding arenas.

Hi,
way/324457236/history ist aber ein großer hot_tub geworden! Hast du dich da evtl. vertippt?

It is ok now. Thanks.

Hi,
this is not a good way to map a horse riding centre (Senante en Selle); it should be mapped once as a separate object (node or area), not different parts of it all as horse riding centres. way/1415178940 is not a horse riding centre; it is a horse riding arena like way/1415158837 and should be tagged with leisure=pitch + sport=equestrian. way/499726098 is also not a horse riding centre; it is just a small building which belongs to the horse riding centre; but since you have removed the tag building=yes it is no longer rendered as a building.

Hi,
ce n'est pas une bonne façon de cartographier un centre équestre (Senante en Selle) ; il devrait être cartographié une fois en tant qu'objet séparé (noeud ou zone), et non pas différentes parties en tant que centres équestres. way/1415178940 n'est pas un centre équestre ; c'est un manège comme way/1415158837 et devrait être étiqueté avec leisure=pitch + sport=equestrian. way/499726098 n'est pas non plus un centre équestre ; c'est juste un petit bâtiment qui appartient au centre équestre ; mais depuis que vous avez enlevé l'étiquette building=yes, il n'est plus cartographié en tant que bâtiment.

Na klar. Bei OSM ist ja sowieso alles freiwillig.

Hi,
I think that a trailhead is not a trail riding station and especially not an equestrian center (leisure=horse_riding) as it is described in the wiki. Here is an example of an equestrian centre:
way/1228517621#map=17/47.747602/-122.142085&layers=P

There is a tag for trailheads (highway=trailhead, used ~15k x), Wouldn't that be more appropriate for a trailhead?

Hi,
relation/19345794 does not look like a horse riding arena (leisure=pitch + sport=equestrian) and way/1412930874 does not look like an equestrian centre; the whole thing is probably this small racecourse: http://murotaht.web.fc2.com/

Hi,
node node/12992811159 correctly represents a riding center (www.thejranch.com), this is ok.
But all the areas that you have mapped and tagged with leisure=horse_riding or leisure=track + sport=horse_racing
way/1413866410 (leisure=horse_riding)
way/1413866413 (leisure=horse_riding)
way/1413866416 (leisure=track + sport=horse_racing)
way/1413866448 (leisure=horse_riding)
don't look like riding centers (leisure=horse_riding) or horse racetracks (leisure=track + sport=horse_racing). They look more like riding arenas (in this case should be tagged with leisure=pitch + sport=equestrian) or something else.

For riding arenas there is a different preset; examples:
way/1282657309
way/1282657310

Freut mich. Ist das denn da dieser Reit und Zuchtstall Witthaut, wie ich das vermutet habe?

Hi,
ich glaube nicht, dass way/1413589929 eine Reitanlage im Sinne von osm.wiki/DE:Tag:leisure=horse_riding ist; dafür ist die Fläche zu klein. Vielleicht gehört sie zu einer Reitanlage, vielleicht zu https://www.facebook.com/profile.php?id=100048679016211 ?
Wahrscheinlich hast du dich verleiten lassen, die kl. Fläche als Reitanlage zu taggen weil daneben auch ein Reitplatz (way/157523493) und eine (vermutliche) Reithalle (way/157522695) fälschlicherweise als Reitanlagen getaggt wurden. Reitplätze werden aber normalerweise mit leisure=pitch getaggt und für Reithallen gibt es osm.wiki/DE:Tag:building=riding_hall .

Jedenfalls sollten mit leisure=horse_riding nicht einzelne Teile, sondern die Reitanlage als Ganzes getaggt werden, vgl. osm.wiki/DE_talk:Tag:leisure=horse_riding#reitplatz_vs_reitanlage

Nicht weit weg wurde eine andere Reitanlage gemappt, wo das ungefähr dementsprechend gemacht wurde (vom gleichen User seltsamerweise): way/159810045

Hi,
You have accidentally removed building=yes from way/159875482. Every building should have a building=* tag, otherwise it will not be rendered as a building on the maps. I have restored it in changeset/168714989.

Tłumaczenie automatyczne:

Cześć,
Przypadkowo usunąłeś building=yes z way/159875482. Każdy budynek powinien mieć tag building=*, w przeciwnym razie nie będzie renderowany jako budynek na mapach. Przywróciłem go w changeset/168714989.

Hi,
area way/159628079 does not look like a horse racetrack (sport=horse_racing). I think it is the area of an equestrian center (https://keio-equestrian.com/) and should be tagged as one, see
osm.wiki/How_to_map_a#Riding_centre_(equestrian)
way/674075993 (example)

¿Qué es eso? ¿Es algo como https://www.camarkprojects.com/post/diseno-y-construccion-de-pesebreras-para-caballos? Entonces el etiquetado correcto sería building=stable (y no leisure=horse_riding). Véase:
osm.wiki/ES:Tag:building=stable
osm.wiki/ES:Tag:leisure=horse_riding

Hi,
I think, way/1411789966 and way/1411789967 should not be tagged with leisure=horse_riding = horse riding centre / jazdecky areal; they should be tagged with leisure=pitch + sport=equestrian for riding arena / jazdecka arena; see osm.wiki/How_to_map_a#Riding_centre_(equestrian) and example: way/89202355#map=18/49.031406/21.201894&layers=P

Automatický preklad:

Ahoj,
Myslím, že way/1411789966 a way/1411789967 by nemali byť označené s leisure=horse_riding = horse riding centre / jazdecký areál; mali by byť označené s leisure=pitch + sport=equestrian pre riding arena / jazdeckú arénu; pozri osm.wiki/How_to_map_a#Riding_centre_(equestrian) a príklad: way/89202355#map=18/49.031406/21.201894&layers=P

Hi,
way/1411633252 is too small for a horse riding center, as described on leisure=horse_riding. It is just some round pen, probably for horse training. These round pens are usually tagged like riding arenas/rings: leisure=pitch + sport=equestrian, example: way/1151081174

Hi,
way/1321737288 seems to be a building. leisure=pitch is not a building type. If it is an indoor arena, you can tag it like way/1298627976

Hi,
way/1410544002 looks like a horse riding arena and not like a horse riding centre; correct? So it should be tagged like way/1344789415 (leisure=pitch + sport=equestrian). If this arena belongs to a horse riding centre, this centre can be mapped as a separate object (node or area) with leisure=horse_riding, example: node/9410229893#map=19/55.927805/23.341464&layers=P

Hi,
wir hatten ja vor ein paar Wochen schon mal diskutiert.
Also, way/1410215852 ist auch keine Reitanlage im Sinne von osm.wiki/DE:Tag:leisure=horse_riding, sondern nur ein Reitplatz (siehe Infobox oben auf der Seite sowie osm.wiki/DE_talk:Tag:leisure=horse_riding#reitplatz_vs_reitanlage). Hier ein Beispiel für eine Reitanlage mit einem Reitplatz: way/657293114#map=19/47.677300/9.950900&layers=P
