Chicago is working the big data pipeline from both ends: Not only will the city glean insights from the analysis of its open data, but it aims to create new ways to generate and collect data.

In July, Chicago will mount sensors on light poles throughout the city, the first stage of a big data collection system whose platform the city will open up to other jurisdictions.

Over the past two years the city has placed a growing emphasis on big data, starting with the appointment of a director of data analytics in 2012. Since then, data coordinators have been appointed in city agencies, part of an open data executive order from Chicago Mayor Rahm Emanuel.
