Globalization: a view from space | Xiaoxiang Zhu
Global urbanization has lead to new challenges for urban planners aiming to reduce poverty and ensure sustainability. To overcome these challenges, we need sufficient data on a global scale. Xiaoxiang Zhu combines satellite and social media data with machine learning to generate a global model of all urban areas. Her models depict 3D shapes and illustrate the functions of buildings, as well as temporal changes, in cities. By providing open access to this data, Xiaoxiang's research group will enable broad impacts globally, from helping authorities improve slum conditions, providing evidence for a more accurate census, and numerous other end goals.
