But there is an argument that any coordinate taken from a Google map
is 'derived data'.  If you went out and surveyed the location with
sextant etc., or read it off a GPS, its not derived from Google.
It's not the numbers that are copyright, its the means by which they
were obtained.

The UK's public mapping agency takes the 'derived data' position,
heres a technical look at it for the sleepless.
