Behind every Google Map, there is a much more complex map that's the key
to your queries but hidden from your view. The deep map contains the
logic of places: their no-left-turns and freeway on-ramps, speed limits
and traffic conditions. This is the data that you're drawing from when
you ask Google to navigate you from point A to point B -- and last week,
Google showed me the internal map and demonstrated how it was built.
It's the first time the company has let anyone watch how the project it
calls GT, or "Ground Truth," actually works.
