That's where I started. After half an hour of trying to decipher their guff, I gave up and posted the question here.

It also appears that much of the Google Maps material is provided by third parties where the guff gets even more unfathomable.
However, Mark, thanks for introducing me to the word guff, which I shall attempt to use as many times as possible during the course of the day. I'm doing quite well already
