Even if we seek to represent reality perfectly, that will never be the reality of map data. We create maps without copying at all! That is the challenge we have set for ourselves.ĭoes OSM have copyright easter eggs? Although some OSMers have deliberately added errors to the OSM data as well (see posting on legal-talk by User:80n), this is strictly discouraged and contrary to OSM policy. The project is not an exercise in copying maps while trying to avoid copyright traps. A campaign exists to change this ( 'Free Our Data') but here at OpenStreetMap we are working around the problem by building an open-licensed free and accurate geodata from scratch. Organisations like the UK's Ordnance Survey have placed their maps under copyright. This is partly to avoid such copyright traps, but also because we genuinely don't want to copy information from these sources. OpenStreetMap asks you not to reference maps when entering data. Accidental errors and minor inaccuracies could also serve as copyright traps.
Fake streets, purpose mis-spellings and phantom churches are all thought to exist. Again this is not a deliberate copyright easter egg by the map makers, though it may look a lot like one.įake street features are fairly hard to find, and we really have no idea how many there are. Many local maps will include these, since mapmakers often produce maps by referring to the plans. A highway developer submits a plan to the government, but never actually builds all the streets. A good example of how this can happen, is "paper street" errors. Of course errors may also serve as a copyright trap in a legal dispute over copyright, but "copyright easter egg" refers to false features or inaccuracies deliberately introduced for the purpose of laying a copyright trap.Įrrors can be introduced for all kinds of reasons, and may look a lot like copyright easter eggs. We have a Catalog of Errors listing more examples. Clearly they don't display major errors like this deliberately (it makes their map unusable in the area!). They have been known to get London tube stations on the wrong side of the river. This is probably just Google making a mistake.
For example Google Maps/Tele Atlas has Patrick's Hill in Cork where Camden Quay should be. There's a fine line between easter eggs and errata.
