Photos: In London, Turning Access into Apps

The City
An initiative of the Greater London Authority (GLA), the London Datastore provides a place on the Web where citizens can freely access the data that the GLA and other public-sector organizations hold. Understanding that a great deal of the information is not in a user-friendly format, the initiative has invited "the masses of technical talent that we have in London" to transform the data into apps, websites and mobile products that people can actually find useful. So far, the plan is working. Developers and others have created apps that offer greater efficiencies in everything from transportation to health care.
