A Decade of Urban Transformation, Seen From Above

A fascinating piece from The Upshot that shows how urban areas have changed over the past ten years, using satellite images. My favourite: How growing ethnic diversity can be seen from space (take a moment to guess what it could be). Have a look at it now. Just as interesting as the final piece is the process of how it came about (in short: an algorithm trained to spot relevant differences in satellite images over time).
