Remains of a collapsed building are no longer a building and should be not tagged as building=*

building=collapsed is problematic for multiple reasons.

  • Remains of a collapsed building are no longer a building and should be not tagged as building=*. Delete the object representing no longer existing building or use demolished:building=* if there is a significant risk that other mappers may mistakenly recreate it.
  • building=* is used to tag the construction type, for example building=church is for any building constructed as a church, no matter how it is used currently. building=collapsed erases distinction between collapsed church, collapsed warehouse, collapsed barn and so on.

How to map no longer existing buildings?

OSM is not a place for mapping no longer existing things.

But sometimes recording that building is gone may be useful, for example to avoid remapping by armchair mappers using outdated aerial images. Consider retagging such objects as demolished:building=* if there is a significant risk that other mappers may mistakenly recreate it.

Once there is no risk of accidental recreation, such objects should be deleted.
