Satellite heartbeat reveals bursty growth in six global cities
Researchers used dense, high-frequency satellite imagery from Landsat and Sentinel-2 to map an "urban pulse" in six cities—Dubai, Lagos, Mexico City, Mumbai, Seattle, and Shenzhen—revealing that urban growth occurs in spikes and asynchronous bursts rather than smoothly; the approach provides near-real-time insights for planners and shows how global shocks like COVID-19 affected cities differently.
