Seattle Heatmap

Seattle is a wonderful city dotted with mediocre Starbucks coffee shops, Amazon construction sites and a beautiful coastal line obscured by the majestic Alaskan highway. After living downtown for over a year, I aggregated my phones location data and plotted the logarithm of the recorded location count:


If I plot the radial distance away from my home on a semilog chart, a linear fit gives an exponential diffusion length (average distance away from home) of 2.1km - which falls perfectly inline with a person who hasn't owned a car in over a decade!
