“An open data movement”

The video below is a speech at TED by?Tim Berners-Lee on how open data around the world is being used from bike lanes in London to elections in Afghanistan. Thrilling to watch…

Open-mapping visualisations and how, after the earthquake, the Open Street Map of Port-au-Prince in Haiti quickly became *the* most accurate map of city following a collaborative effort of people around the world to process satellite data.

Thanks to my colleague, Heather White Laird for the point.
