Strava is a running and cycling app that recently unveiled its new Heatmap: an interactive map of the global sports activities of its users. GPS data points are generated by the entire community of Strava‘s users.
Recently they released a global heatmap of 77,688,848 rides and 19,660,163 runs from the Strava dataset. The developers said that this was more of an engineering challenge to create a visualization of that size than anything else. But still, the maps reveal a pleasant aesthetic, for example the activity charts in Paris, London, Los Angeles, or even Everest, or Burning Man are particularly graphic.
