What does where we tweet say about how we live and work?
Jan 28
That’s one of the questions Oakland-based programmer Eric Fischer hoped to answer with his latest mapping project.
Fischer, a mapping fanatic and artist, is used to displaying vast amounts of information in visually compelling ways. In his latest project, he manages to plot out the motion of New Yorkers using public tweets on Twitterwith geotags from May 2011 until January.
The project lays out around 10,000 geotagged tweets and 30,000 point-to-point trips in cities like New York City to plot the flow of people in terms of favored paths. In his map of NYC, seen above, there is a huge ink blot lining Broadway; as we’ve long suspected, it looks like the busy avenue is the backbone of the city.
Using a base map from OpenStreetMap, he drew out transit paths using Tweets. Movements are indicated on the geolocation of a Tweet, with an individual’s start point marked with one geotagged Tweet and ending with the next geotagged Tweet. This is what creates a mass of traffic routes.
