Geocaching.com told Ed that he must comply with their "requests to put copyright notices on all geocaching data". Ed had to bring his site down for one week while he sought legal advice to determine if gps locations can be copyrighted. His lawyers told him everything is legitimate and his maps are back up! I don't think this fight is over yet but it will be interesting to see if gps location information can be copyrighted." This redoubles my current ambition to find an inexpensive, decent GPS receiver. Then I can copyright everywhere I go and charge royalties for visiting.
