Researchers have identified a measurable “urban pulse” in six global cities – Dubai, Lagos, Mexico City, Mumbai, Seattle, and Shenzhen – by analyzing satellite imagery. The study, conducted by observing dynamic changes in near real-time, suggests cities exhibit behaviors akin to living organisms, including periods of growth and change. This new method of tracking urban development utilizes satellite data to monitor a city’s “vital signs.” The findings indicate each city possesses a unique pattern of expansion and evolution. Scientists believe this approach can provide valuable insights into urban planning and sustainability efforts. The research highlights the potential of satellite technology to monitor and understand complex urban systems.
