The very term “big data” sounds impersonal and unwieldy. Yet, as experts from Georgetown University’s third annual Smart Cities Assembly show, this explosion of information is being used by urban planners to support a more human-centered planning process. This new process looks at how urban spaces—from whole regions to individual buildings and even portions of buildings—are impacting the daily lives of the people who live and work in them. Uwe Brandes, faculty director of Georgetown’s graduate program in Urban & Regional Planning, leads a discussion of how this new data is transforming urban planning.
