Don't think it ever happens, or don't think that google does it? I think it used to happen. Cecil Adams / Straight Dope, Source Of All That Is Truthful, has some examples where mapmakers intentionally put false streets etc into their maps. http://www.straightdope.com/columns/read/1058/do-maps-have-copyright-traps-to-permit-detection-of-unauthorized-copies Does google do it? In the past they purchased their map data from other companies (so why would they have bothered or cared?). But they are now getting into the game of creating and owning their own maps. It's nice that they give people a way to report issues, but that doesn't preclude the possibility that they participate in similar shenanigans. http://searchengineland.com/no-more-teleatlas-google-goes-it-alone-for-maps-data-27584 --------------------------- Sam [GPS nerd] -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
