Ollie here in CASA has just posted a new temporary panel on the London CityDashboard which shows Twitter activity at the London 2012 venues. The panel is using data from new Twitter collector tools in the Big Data Toolkit, developed by Steven James Gray, again CASA, as part of his PhD.
As Ollie notes ‘for each venue, the collectors count the number of Tweets in the last hour that have latitude/longitude information stamped on them, that are located within an area radiating around the centre of each stadium or arena. Its worth noting that this excludes the majority of relevant tweets, as most mobile Twitter applications don’t include this information by default’, you have to turn on Geo Location.

You can view the live data either within our other feeds via our London CityDashboard or direct at http://bigdata.casa.ucl.ac.uk/olympics/
For more detailed information take a look at Ollie’s Suprageography site and Steven’s Big Data Toolkit.
