An anonymous reader notes that Google now makes it possible to edit the map location designated by (almost) any address. Registered Google users in the US, Australia, and New Zealand can move incorrect markers for their homes or businesses
to the correct locations. Access to some listings is restricted — hospitals, government buildings, and businesses whose listings have been claimed through Google's Local Business Center. In addition, moving a place marker more than 200 yards (or 200 meters) from its original location requires a moderator's approval before the change shows up on the map. Once a marker has been moved, a "Show Original" link will direct users to the original location.
