Of course (^^), we only add the mandatory field for an address in Belgium which are "housenumber", "street", "postal code" and "municipality" (you never need anything else to send a mail to someone in Belgium. And the spatial query for a region/country is a lot less demanding in ressource as the polygon are really big (it is related at how the data is organised and how the spatial query work).

Yes the query in overpass can get the underlying address from the building or the boundary polygon (for postal code and municipality...) but as said, it is just demanding in ressources for the server when doing it a lot of times, while duplicating the data on the POI point is not really problematic (as storage space is really not a big deal for OSM) and it allow the query to run a few magnitude faster (like 1 second for 1000 POIs address geocoding in overpass, instead of 100 seconds -> i don't have exact numbers but it is to give an idea).

Yes, i agree with you on that. But we generally tag both the physical address on the building (as it should if it is the only address) and on the POI node (it is a duplicate but far easier to query it - so it is often done). Then if we delete the POI, it doesn't matter as the address is on the building but at least we can just query directly the POI and get its address without needing to make spatial query/geocoding. It is so demanding in resources to make spatial query that the double tagging is generally "tolerated" (not for one POI but doing it for 1000 or 1 million POI is really demanding).

Hello Jakka,

Is there a reason that you removed addresses on the company node ? I know it can be spatial query from the building, but, as far as i know, it is widely accepted in Belgium to keep addresses on POI (shops, companies, ...) as it make it far more easier (and less resource demanding) to query.

Kind regards,
Anakil

Hello, just a small thing, the "access=yes" tag is generally not useful as the specific access are already mentioned on the way : look at the decision tree here osm.wiki/Key:access . Here all types of vehicle already have an access tag specific to them, so the general access is not needed.

Oh and you are really active it seems, if you want to discuss with the community, don't hesitate to join us on the chat riot ! https://riot.im/app/#/group/+osmbe:matrix.org

Happy mapping ! ;-)

Hello Staerwrathn,

You added highway on top of other existing highways (which is considered vandalism). I moved the tags of maxspeed on the "residential street" you created, on the existing tertiary street.

Try to look at the existing object when editing before adding new ones. ;-)

Happy mapping. ;-)

Hello Huibc,

Thanks for your contributions ! Just a small improvement on the addresses tagging. Not every building need an address, only some buildings have one (like houses). You also don't need to put the country or the municipality in the addresses as they are implied by the boundary (like this for the postal code osm.org/relation/4727592#map=13/50.7735/4.7683&layers=N ). The only mandatory information (in Belgium) are the "housenumber", the "streetname" (and the postal code if it is different than the usual one in the municipality). In belgium, you really only need the tags "addr:street" and "addr:housenumber" (and optionally "addr:postcode", "addr:city"). Example for this building : addr:housenumber=3 , addr:streetname=Rue du Rivage, (and optionally) addr:postcode=1320, addr:city=Beauvechain.

If you look on the background layer (the "paper layer" symbol on the right when editing) of the PICC for Wallonia, you can see the housenumber when there is one officially (it is inside the polygon). Sometimes it can be wrong but then it need survey on the ground.

Happy mapping. ;-)

Hi Dylan Deroover,

Thanks for your contributions, just a quick hint : try to put the name of the shop in "name" category and after only in the name in specific language (like in "English" here as it is in the tag "name:en" not in the tag "name"). I don't know how it works on Maps.me but i suppose it is possible.

Happy mapping,

Hello WatsonF,

Thanks for your contributions ! Just an improvement for further edits : try to trace as accurately as possible (zoom in, we have good imagery and others detailed plan layers (like PICC) in Wallonia). And if the building is squared, don't forget to square the angle (button 'S' or right-click > Square in ID editor when finished tracing).

And please do not delete additional attribute or data, if you see a badly drawn buildings (or anything), try to re-use the existing geometry and redraw it without deleting it (Hint: you can double click on a line to create new points if needed in ID editor). It also keep the history of the object.
=> You had deleted the address of one building without re-adding it, after redrawing it.

Happy mapping ! ;-)

Bonjour nervien,

Attention tu avais faits plusieurs erreurs et incohérences ici. Tu avais créer un second chemin exactement au même endroit que celui existant et ajouté des relations/tags un peu bizarre (comme une relation liée aux pistes de skis ?!). J'ai supprimé cela et les tags incohérent sur les chemins alentours (un accès=yes à tous les types de véhicule alors que l'accès général est mis à "privé" (ce qui ne veut rien dire car tous les véhicules ont un accès d'après les autres tags), j'ai donc laissé uniquement access=private (accès privé pour tous par défaut).

Attention à cartographier avec un maximum de qualité car ce que tu édites est mis en ligne pour TOUS (et beaucoup de monde/ applications utilise OpenStreetMap), n'hésites pas à lire le wiki décrivant les attributs (tags) à ajouter. osm.wiki/FR:Page_principale

Bien à toi,

Hi Wajt,
Thanks for contributing ! I saw a small mistake here. The correct tagging for houses is "building=house" ("huis") (not "place=isolated_dwelling").

Happy mapping,

Bonjour debonra,
Merci de ta contribution ! Juste un petit conseil : essaye d'ajouter le nom de rue (et potentiellement le code postal) quand tu ajoute une addresse à un bâtiment (et donc, ne pas se limiter au numéro). Car en Belgique, une adresse a toujours besoin de ces 3 éléments (avec le numéro) pour être complète. ;-)

Hi Paulo1b, thanks for your contribution. A small problem i see is that you had "broken" the polygon of the building by not "connecting the node" when deleting one part of it.
I corrected it, but watch out when deleting things ! ;-)

Bonjour Jacques Rezer,

Merci de ta contribution. Attention à ne pas oublier de mettre les attributs ("tags") après avoir tracé des points, lignes ou polygones ! Aussi attention à bien faire des polygones pour les maisons (une ligne fermée qui se finit où elle a commencé) et pas un zig-zag comme c'était le cas pour un des bâtiments).

Happy mapping,

Re-bonjour,

Un autre petit commentaire, concernant plusieurs changements dans cette zones.
J'ai vu que sur toute une série d'endroits, tu avais ajouté des points sans aucune information (probablement des clics perdus / sans faire attention). Attention à corriger les erreurs avant de sauvegarder, pour ne pas pas laisser d'éléments sans attributs (souvent ajouter par erreur). :-)
J'ai déjà nettoyé cette zone, mais je n'ai pas vérifier partout.

Happy mapping

Bonjour jfonda,

Merci de tes contributions, juste une petite erreur (ou oubli): tu avais dessiné la chapelle sans mettre d'attributs ("tags") sur le polygone (et tu avais mis l'information chapelle dans le nom sur un point à côté). J'ai corrigé le tout en plaçant l'information sur le polygone du bâtiment directement. ;-)

Happy mapping

Le site du patrimoine stephanois décrit par exemple ce mémorial ainsi http://www.patrimoine-stephanois.be/New_Site1/files/descriptifs_promenades/promenade_3_descriptif.pdf

Bonjour querrix, Merci de ta contributions,
je vois juste que tu as ajouté de nombreux polygones sans indiquer de tags dessus ! (J'imagine que ce sont tous les bâtiments, j'ai donc mis building=yes à tous).

Il ne faut pas oublier de donner une valeur au polygone après l'avoir tracé ! ;-)

Happy mapping !

Bonjour Himanthalia, l'école de langue vivante est déjà taggée sur l'entrée ici osm.org/node/4898179605

Bonjour Chawette,

J'aimerais savoir quels sont tes raisons de rechanger les tags de ces deux objets ? En Belgique, les mutualités sont taggées avec "office=health_insurance".

Et d'après ce que j'ai pu en voir dans les descriptions sur internet et sur l'image, le monument est bien un ancien marteau pilon (et non une presse).

Quels sont donc tes raisons d'indiquer cela ?

Bien à toi,
