The rise of big data that is geospatially referenced enables organizations and individuals to utilize new analytical techniques and approaches to identify patterns of social inequity and organize resources to address and correct these inequities where they exist. The range of social issues where the “data of social justice” can provide a deeper understanding of the scope and magnitude of inequities extends across complex issues including global hunger and disease, income and social inequality, criminal justice and mass incarceration, legal reform, ecology and climate change, political unrest and social change, and economics and productivity. Geothink’s researchers have used big data, crowdsourced data, and new open datasets in conjunction with mapping technologies, applications (apps), and Web 2.0 software to analyze social problems and provide practical solutions. This work has included improving urban accessibility for those living with disabilities and helping the homeless to more easily find urban services. This panel of experts will bring together leading academic experts to discuss the opportunities, challenges, and implications of this work with a focus on its application in cities across the world.
