The Flowing city is a collection of projects that Margarida Fonseca found while searching for information visualization projects about cities and it is also the name of her thesis.
Some of these projects visualize community generated data, or in other words they use crowdsourced data like for instance Mappiness.
Other projects visualize Real world data – data from monitoring systems (Sensors, RFID, etc) – or visualize data from Open data agencies or ultimately they visualize proprietary data. Despite the data source, what they all have in common is offering a new perspective of the cartography of the city.
