My love of maps is no secret, and the recent graphics over at New Scientist of transportation time, based on "how long it would take to travel to the nearest city of 50,000 or more people by land or water", are amazing. By that definition, they find that "less than 10% of the world's land is more than 48 hours of ground-based travel from the nearest city".
Where is the most remote place on the planet? It looks like it's the Tibetan plateau, where it takes up to three weeks to get to a town.
And Chris Blattman found a great map of the US transportation network, depicted as a human body.
