In 99% of cases, I doubt it the work done by Google
would be enough to
obtain copyright protection. Most of the time it isn't even something
done by hand, it's something done by computer.
I think Google have done enough for it to count as a derived work.
It's not just a compilation of images, they are put together in a very
careful and precise way. As far as I know, it doesn't matter if
something is done by hand or by computer - it's still copyrightable.
