Finding the Remotest Place on Earth

Surprising results in the article Where's the remotest place on Earth? in New Scientist magazine summarized by this map: "less than 10 per cent of the world's land is more than 48 hours of ground-based travel from the nearest city."

Having traveled between Kathmandu, Nepal and Lhasa, Tibet (Tibet, like Greenland, looks very remote on the map), I'd note that the "ground-based travel" the article refers to must be by big, hearty vehicles.

Leaving Kathmandu by LandCruiser, we arrived at Xigatse, Tibet's second city, on the third day.

There's a larger map alongside the article itself.
