The thought process (note: I do not agree with it)
goes like this:
* A map or a sattelite photograph is copyrighted material

In US copyright law, "A “derivative work” is a work based upon one or
more pre-existing works". Since a pair of coordinates is not a work, it
can not be a derivative work, even if it is based upon one or more
pre-existing works.
