The Atlas of urban expansion- how do cities grow?

The Atlas of Urban Expansion collects and analyzes data on the quantity and quality of urban expansion in a stratified global sample of 200 cities. With the aid of satellite images researchers have gathered a rich dataset on built-up areas and the associated land use regulations and policies that sheds light on the process of expansion of urban peripheries since 1990. Besides, for a sample of 30 cities, researchers gathered historical data on urban expansion from 1800 to 2014 and used it to generate visually appealing animations that show intuitively the process of urban growth. See, for example, the animation of Los Angeles below.

The Atlas of Urban expansion is a joint initiative by NYU Urban Expansion Program, the Stern school of Business at NYU in partnership with UN-Habitat and the Lincoln Institute of Land Policy.

The Atlas can be freely downloaded, and a number of urban data, maps and metrics can be also downloaded.
