This great project aims “to reveal the rhythm of the city as it occurs, in real time.” I first got to know them at a congress about tracking technologies organized by the TU Delft when I was PhD student. Then they presented their Real Time Rome project, a project they developed for the 2006 Venice Biennale. Here, they used information provided by mobile and public transport company to map the use of urban space in Rome in real time. They produced videos of fluxes of people in the city with different events, for example Madonna’s concert and the final of the world-cup that Italy won. The images underneath are from those events but in their website you can see the videos and understand how they really get a grid of the movement of crowds through the city and how different areas are more densely used at different times. For example, after the worldcup, people using mobiles is concentrated in the bars and clubs areas of Rome.
In the website of the SENSEable City Lab you can see the large amount of great projects they are developing after this pioneer 2006 project. Check for example the Live Singapore that “presents five different perspectives into Singapore’s urban dynamics using graphic visualisations of selected digital data generated by people in Singapore and their actions.”
This entry is dedicated to the work of Charles Joseph Minard (1781-1870). Even though Minard only became cartographer a a later stage in his career, the work he produced is an obligated reference to anyone dealing with mapping, specially referring to maps that combine information and data to communicate a message.
