A Satellite View of City Growth, in GIFs
Watch these 11 cities boom over recent decades. From space. In animated GIFs.
NASA's Landsat satellite system has been orbiting and taking pictures of the earth since 1972. In honor of its 40th birthday, NASA and the U.S. Geological Survey have released a cool set of images showing how 11 world cities have changed over that time. This site features two overlaid images of each city from different years dating back to the 1970s, with a cool slider bar to let you see how each city has changed. To make the drastic changes of time even more apparent, we've made some animated GIFs of those images.
