(If you follow this logic to its red-herring end-point, then cartographers are now basically creating 'broken' maps - deliberately incorporating error as a form of digital-rights management - a weird reversal of what you traditionally might think map-making is 'about': the accurate recording / transcription of physical space. It's a weird idea, the creation of false maps ("Ah, but you're just misnaming," I hear you say. "It doesn't - or shouldn't - interfer with navigation." Sure, but it's still a form of falsification and one that's interesting to meditate on. (Some trap streets are deliberately misdrawn with non-existent corners or bends, or presented as too narrow to be a thoroughfare). I thought that broken maps were only produced during wartime or periods of territorial gerrymandering - but, apparently not. It's also worth thinking about the role of traditional map-making in the era of uberhi-res satellite-imaging: is it now not roughly analogous to that of painting in the early years of photography?)
(I think I first came across the concept of trap streets in a (non-cartographical context in a ) China Miéville novel. Kraken, maybe? He certainly sort of visits that idea in The City and The City - the idea of two cities co-existing in the same physical space, but with different inhabitants, street names, etc)
In a weird legal twist, though, apparently it is not possible to copyright the names (or descriptions?) of the trap streets themself. To wit:
"To treat "false" facts interspersed among actual facts and represented as actual facts as fiction would mean that no one could ever reproduce or copy actual facts without risk of reproducing a false fact and thereby violating a copyright. If such were the law, information could never be reproduced or widely disseminated. But even though facts themselves are not copyrightable, the order, selection, and presentation may be copyrighted." I really like that idea; it appeals to me.
Anyway, this sounded interesting:
"When a young, somewhat naive intern at a company that makes digital maps bumps into an attractive woman one day, he is unable to find her again. The street where he met her and where, according to her business card, she works turns out not to exist."
