I noticed recently that much valid data keeps disappearing from OSM. Is this some kind of cleanup or just vandalism? How can I check who has deleted a particular object? Is the deleted data stored somewhere i.e. is there "undelete"? Is there any protection policy in OSM? |

Hi, You've covered a few bits with your questions, but I'll do my best;
Hope my somewhat wordy answer is some help to you. Regards Tallguy 2
We really need to implement a proper "download deleted objects in this area" api call, and support in editors. This is a FAQ, but we still have no convenient answer.

Most likely you are referring to the effects of the license change, see e.g. this previous question: http://help.openstreetmap.org/questions/14526/osmf-redaction-account-huge-amount-of-data-deleted If you are not, ignore this answer. |

When you ask about data disappearing it is always helpful to give a link to the specific object(s) or the place where the object(s) used to be. A generic question as above can only be answered generic if anyhow. |

You should really improve your question by specifying if you are speaking about the "license change effect" or "data deleted by someone else". Because the answer will be different : For the first, the license transition withdrawn many objects because they did not comply with the new ODbl license. Those data cannot be retrieved and need a new survey (check the "remapping" task on the wiki). For the second, it is possible to restore the deleted objects; see the hints provided by other answers on this page. |
