• A lidar map of the world: the ground beneath the trees

  

  Fifteen national laser surveys in one zoomable map. Hillforts hidden in forests, the craters of Verdun, the mine craters of Messines, Roman gold mines and the biggest burial mound in Japan: what the land looks like with every tree and building taken away.

• Where languages come from: every language on one map, with its family tree, its future and its homeland

  

  7,674 spoken languages, 421 separate lineages, 52.1% endangered. I mapped every language in Glottolog with its family tree, endangerment, speaker numbers and the proposed homelands of the great language families.

• How deep is the sea? The ocean floor, its trenches and seamounts, on one map

  

  A map of the floor of the whole ocean, sharp from ocean basins to seamounts. The average sea floor lies 3,675 m down, 74% of it is abyssal, the Challenger Deep would hide Everest with 2,086 m to spare, and only 28.7% of the floor is mapped to modern standards.

• Junk on the Moon and Mars: every human-made object on two worlds, mapped

  

  I mapped every human-made object on the Moon and Mars from Wikipedia’s lists: 133 on the Moon and 27 on Mars, 203 tonnes and 10.4 tonnes. A third of the Moon’s junk is five Saturn V rocket stages, and almost all of it is dead.

• Where the wind blows: the world’s winds, and are wind farms in the windy places?

  

  I mapped the world’s winds month by month, from the trade winds to the Roaring Forties and the monsoon, and set 5,344 wind farms against the wind at their sites. 82% of onshore capacity stands on ground windier than its country’s median.
