What Happened to Google Maps?
I'm surprised the author didn't mention the main difference between paper maps and google maps. That is, google maps is interactive. With a paper map what you see is what you get. You had to cram as much information as it would allow. But this is not the case with google maps. You can zoom in, out, and anywhere in between. You can't compare the two based on the level of information displayed at one fixed zoom level because google maps is 3D whereas traditional paper maps are 2D.
