A 3D map of buildings in central London has been produced entirely from people's tweets.
Two students from UCL combined the 3D mapping technology with 'geo-tagged' tweets, revealing which buildings the tweets are sent from.
The end result, a view of London you've never seen before.
The taller and darker the buildings show where the most geo-tagged tweets were sent.
The data was monitored for nearly 16 hours with over 3,500 tweets analysed
London's tweeting hotspots include:
Marble Arch - 63 tweets
St Pauls - 58 tweets
Kings Cross - 33 tweets
British Museum - 28 tweets
Paddington - 26 Tweets
Waterloo - 24 tweets
Knightsbridge - 18 tweets
Stephan Hugel claims that any source of real-time data can be visualised through the shape, height and colour of objects on a 3D map.
The pair are looking to expand the type of information they use, and are currently investigating whether air-quality readings in cities can be represented through the technology.
