|abandoned = yes|
|A man-made feature abandoned and no longer maintained. Also see abandoned:=* namespace.|
|Used on these elements|
|Tools for this tag|
- Use of this tag is discouraged for some features and situations. See Comparison of life cycle concepts for a general description of how to tag the various stages of a features stages of planning, construction, operation, disuse and decay.
The abandoned=yes tag is used for building=* and other man-made features that have fallen into serious disrepair, appear to be unused, and can not be put back into operation without expensive repair, yet remain identifiable as the same feature.
Use of this tag is discouraged for some features, and where more than one main feature is tagged on the same database element (see One feature, one OSM element).
How to Map
- A simple feature such as an Tag:man_made=adit which has fallen into decay is tagged with man_made=adit + abandoned=yes.
- Caution: for more complex features with multiple tags it is sometimes unclear which tags are still relevant, and which are not. For example railway=rail + abandoned=yes + highway=track +surface=paved. Does the abandoned tag refer to the railway, the highway or both? Does it also refer to the surface tag? In this case using the abandoned:=* prefix namespace for specific tags is clearer. Also see One feature, one OSM element - multiple main features should not share the same geometry.
- Some features may still be reasonably tagged with abandoned=yes, for example building=house with abandoned=yes could represent an unoccupied and unmaintained house, which is still clearly a house. It might be repaired and occupied again in the future, or demolished.
Abandoned=yes vs Abandoned:key=* namespace
|Image||Ambiguous tagging||Preferred tagging||Description|
name=The little bike repair shop
old_name=The little bike repair shop
|Derelict bike repair shop that can't be brought back into use easily. It's still a retail building, however: most of the roof's still on, and the walls are standing. The tagging reflects its former use, its state of abandonment, and the fact it's still a building.|
name=The old road
name=The old road
|Subsided former turnpike road in Derbyshire, UK, abandoned in the 1970s as a result of a landslide. Still somewhat passable on foot and by bicycle, so it retains a (new, different) highway tag, and a reference number.|
|landuse=quarry + abandoned=yes||Abandoned and partially flooded quarry. Note that lifecycle scheme is not used here - that is because quarry describes landscape feature, not company operating there. This is a rare case where abandoned=yes is still recommended.|
|railway=rail + abandoned=yes + highway=footway + surface=unpaved||railway=abandoned + highway=footway + surface=unpaved||Abandoned railway - the railway grade, including embankments and cuttings, is still visible, but the rails have been removed and the right-of-way is now used as a footpath . A special tag railway=abandoned is used.|
