The resulting maps are generated entirely from 2.5 million unique GPS points (about 1 point per 2 to 6 seconds), which were tracked by his iPhone or Android phone for the past 3.5 years (resulting also in some interesting battery issues).
The trajectories and itineraries on the maps have been colored by year, in order to reveal how his physical footprint changes over time due to the different locations of his house.
