Where are you when you tweet? And where are you headed to next?
Eric Fischer, a programmer and mapping enthusiast from Oakland, California, has created a unique way of showing how our interactive environments can track our physical trajectories through space.
He has created a series of maps of various cities that show people's transit routes based on the geolocation of their tweets. More specifically, he took a mapping start point based on a given Twitter user's location for one tweet, and then drew a line to where that person had arrived by the time they tweeted next. From that data - multiplied over 10,000 randomly selected geotags - he created a map showing the highest density of tweeting traffic in the city and the routes taken. (Rather than draw lines as the crow flies, Fischer used actual "plausible" routes.)
That giant, black blobby line in the centre of the New York City map below? That's Broadway, a route along which many people appear to be tapping the screens of their phones while they move through the city.
Anyone familiar with Toronto's transit system will also recognize the tell-tale shape on Fischer's map of that city:
As will anyone who gets around Vancouver on a regular basis:
