Global urbanization creates challenges for poverty reduction and sustainability. Xiaoxiang Zhu addresses this by developing a global model of urban areas, using satellite and social media data

Global urbanization creates challenges for poverty reduction and sustainability. Xiaoxiang Zhu addresses this by developing a global model of urban areas, using satellite and social media data with machine learning. Her models depict 3D building shapes, functions, and temporal changes. Open access to this data will enable broad global impacts, from improving slum conditions to providing more accurate census information.

A professor at TUM specializing in Signal Processing in Earth Observation, Xiaoxiang Zhu combines her lifelong fascination with space and mathematics in her work. This talk was delivered at an independently organized TEDx event. Learn more at https://www.ted.com/tedx.
