FlowingData brings us the news on Anil Bawa-Cavia’s Achipelago project that attempts to organize 845,000 FourSquare checkins into visible patterns across a few major cities.
In these maps, activity on the Foursquare network is aggregated onto a grid of ‘walkable’ cells (each one 400×400 meters in size) represented by dots. The size of each dot corresponds to the level of activity in that cell. By this process we can see social centers emerge in each city.
There is an obvious bias in the data, since it’s solely linked to users of FourSquare, but it’s interesting to see how ‘even’ Paris is compared to New York City.
