What do erosion, urban planning, food insecurity, disaster relief, and the hunt for lost cities have for common? Big data can help identify and solve those problems--that's the domain of our guest this week, UVA Professor Dr. Bill Basener. Dr Basener is a Professor at the School of Data Science and a genuine polymath, with publications in machine learning, signal processing, game theory, ecological economics, evolutionary genetics, and more. In this episode, he discusses how remote sensing techniques--long range images of the Earth taken by satellites and aircrafts--and how he and other scientists use that data to identify what's on the ground and how society can help.
