The project is a collaboration between academics and urban planners focused on understanding long-term urban trends. Users can explore interactive maps to see, for instance, how much London or Tokyo has expanded from 1960 to 2020, observing the patterns of development.

Why It’s Useful
Many people are familiar with modern satellite maps, but understanding urban development historically is often confined to academic circles or static infographics. The Atlas of Urban Expansion makes this complex data accessible and visually engaging through interactive timelines and comparisons. It goes beyond simply showing city outlines; it visualizes the density and extent of human settlement, allowing for fascinating comparisons between different cities and different eras. For urban planners, geographers, historians, or even curious individuals, it provides an unparalleled tool for understanding the forces that shape our built environment. It's a powerful resource for visualizing macro-level change that is often imperceptible in daily life, revealing the dramatic and often rapid transformation of landscapes over decades.
