1.3.4. Edit rollback rules

If you undo an edit, then you must write the user a note explaining why it was necessary. If you undo several of a user's edits of the same type, then you only need to write one explanation.

Typical reasons for rejecting edits (also see the Moderation section):

  • Duplicate item: the map item that was created already exists on the map, so the item was deleted as a duplicate.


    Make sure that the duplicate item doesn't contain any new information. In this case, you may need to move information about an item that was created earlier or delete the item after you save a copy (duplicate) of it.

  • Fictional map item: the item doesn't exist in reality, so the edit can't be accepted.

    Note. These items are frequently created in order to test the service out.
  • Construction has not yet begun on the item: the item does not exist yet in reality, so it can't be accepted at the moment. The item may be added to the map as soon as construction gets underway.

  • The creation of objects that not drawn according to the Rules: some military objects, private sector fence areas, driveways inside private areas, and so on. the List of objects that are forbidden to display, see the section 3.1.4. Forbidden items .

  • Invalid map item category: when the item was created the wrong category was chosen so the edits can't be accepted.

  • Erroneous attribute edit: the attribute edit can not be accepted since it does not follow the Drawing Rules.

  • Erroneous shape edit: the shape edit can not be accepted since it does not follow the Drawing Rules.

  • Unmappable item: these types of items (fences surrounding private property, small parking areas, playgrounds, etc.) are not drawn in respect for the apps that use YME data.

  • Other: the reason isn't described above. For example, edits that contain a lot of erroneous attribute changes (this frequently happens with map items in the “Roads” and “Locations” categories).

  • Vandalism: undo edits that are obvious examples of vandalism and ruin existing items.


    Make sure that there are no correct edits containing new information about a map item among the "vandal" edits. If the edit contains useful new information, make sure to save it.
