Hansen, Potapov, Moore, Hancher et al. produced high-resolution maps of global forestry to estimate change between 2000 and 2012. Quantification of global forest change has been lacking despite the recognized…

Running traces

The Endomondo app lets you keep track of your workouts, namely running and cycling, so it records your location, and then estimates your speed, calories burned, and elevation changes. And…

Estimated coastlines if the ice melted
