Last November, Strava Labs released its "global heatmap" -- a stockpile of data created by millions of health-conscious people worldwide. Strava Labs is the GPS brain many fitness trackers rely on, allowing devices to record billions of steps recorded by millions of users. The company pulls data from big players like FitBit and Jawbone, as well as having its own fitness-tracking app. Here's what Strava Labs handed over to the general public:
1 billion activities
3 trillion latitude/longitude points
13 trillion pixels rasterized
10 terabytes of raw input data
A total distance of 27 billion km (17 billion miles)
A total recorded activity duration of 200 thousand years
5% of all land on Earth covered by tiles
