As Mr. Spock (my idol) would say: "Fascinating!"

An astonishing new map has revealed the elevation of nearly every place on Earth. The Global Digital Elevation Model was created using nearly 1.3million images collected by a Japanese camera on board Nasa's Terra spacecraft. It is made up of a giant grid of 23,000 tiles, with each height point spaced 98ft apart. It shows a detailed representation of the planet's land mass. In this colourised version, low elevations are purple, medium elevations are greens and yellows, and high elevations are orange, red and white.
