While a city is not a living organism, it behaves very much like one. Its metabolic processes may be manifested in growth spurts, metamorphosis over time and even decay. Researchers using satellite imagery have tracked the vital signs of six major global cities, detecting a distinctive “urban pulse” in each.
The researchers looked at Dubai, Lagos, Mexico City, Mumbai, Seattle and Shenzhen using a new way to document dynamic changes unfolding in each of these cities in near real-time.
虽然城市不是生命体，但它的行为非常像生命体。它的新陈代谢过程可能体现在增长暴发、随时间变形甚至衰败中。研究人员利用卫星图像追踪了六个全球主要城市的生命体征，检测到每个城市独特的“城市脉搏”。
研究人员选取了迪拜、拉哥斯、墨西哥城、孟买、西雅图和深圳，采用一种新方法记录这些城市的动态变化，几乎实时进行。
