while the previous answers are correct in that GPS coordinates, in and of themselves, can not be copyrighted, I think you find that a particualr compilation of them will be very much copyrightable. Take English words, for example. Not one of the words in Steven King s new novel can be copyrighted by itself (unless he coins a new word), but his particular compilation of words into a novel will be vey well copyrighted.
GPS coordinates ARE NOT copyrighted materials. Those coordinates have been around for HUNDREDS of years. No one owns a reference to a location.
