Statut: Utilisé

Résumé

En anglais, un disused feature désigne n'importe quelle construction humaine désaffectée ; cette construction a perdu son usage principal, mais est toujours maintenue et réparée. On peut supposer que sa remise en service est possible. Une telle construction peut se révéler utile pour s'orienter dans le paysage, surtout si elle porte encore des pancartes ou des indications diverses.

Si la construction est complètement abandonnée, utiliser plutôt la clé abandoned=*.

Comment étiqueter

  • When a feature falls into disuse, begin by adding the tag disused=yes to it.
    Adding this tag implies lots of things about the general level of human activity present in and around the object, but by itself isn't sufficient to describe the object's status consistently. To make the tags internally consistent:
  • You must also make any tags which no longer have current meaning as a result of the disuse unavailable to software which doesn't know about the disused=yes tag. This can be done by prefixing their keys with the namespace disused: — see the examples below.

Examples

Image Tagging Description
Closed down shop.jpg disused=yes
disused:shop=yes
A closed-down shop of some sort. If the type of shop it used to be is known, substitute the appropriate value from Key:shop for "yes".
Disused-or-abandoned-pub.jpg disused=yes
disused:amenity=pub
disused:operator=The Oxford Pub Company
name=Fox & Hounds
Boarded-up disused public house. It no longer has an operator as such - no beer is sold - but the name is still useful for navigation.
Leisurepitchdisused.png disused=yes
disused:leisure=pitch
Disused pitch, now somewhat overgrown.

Disabling no-longer-meaningful tags

This tag has a long and shambolic history, but is in use in the database. In practice, computer programs which use OSM data such as renderers or routing engines cannot be expected to distinguish between, say, a parking structure tagged just as amenity=parking, and one marked both amenity=parking and disused=yes without special rules. Therefore it's necessary to tweak the tagging so that such programs do not see confusing data.

In the spirit of the original proposal, and because the key was discussed and voted on, it makes most sense to move disused properties into a disused:* namespace prefix. This also solves the problem of potentially confusing data.

NOTE: this form makes the object's tagging inconsistent, and is STRONGLY discouraged. If you see instances of this, please fix them.

disused=yes
disused:amenity=parking
disused:capacity=20

Much better! Software won't accidentally render it now, or direct drivers to boarded-up parking lots. The fact of disuse is captured concisely too.

Using the namespace prefix also has the advantage of being easy to undo at a later date if the object goes back to its exact previous use.

Guidance and life-cycle

  • Really this is only for objects which have no current functional use beyond their physical form.
  • If the name is still meaningful to people and is still written on the building, by all means retain it (or perhaps move it to old_name=*.
  • In general, retain tags which are still relevant, and move tags which aren't.
  • An example: if the object is a building which has fallen into disuse but is still structurally sound, don't move its building=* tag into the disused: namespace. Just walls and a roof make it still a building, so that tag is still meaningful.
  • If something comes back into use, be sure to clean up the entirety of the disused:*=* and disused=* namespace when you retag it.
