In this ﬁrst project Anil bawa-cavia looked at the social life of cities. The city of social interactions.
What he has done is produce bottom-up images of cities by mapping millions of events on Foursquare, a location based social network. This is an image of New York City constructed from 600,000 GPS events on the Foursquare network. Each event is a user checking-in to a social venue (a bar, restaurant, art gallery, nightclub, etc) on their mobile phone, in order to let their friends know where they are. Each dot represents a walkable cell of 400×400 meters and its size is proportional to Foursquare activity over a year. By this process, recognisable social hubs emerge. You can see Midtown, Central Park, Lower East Side, Williamsburg on here.
