Drying of the Aral Sea: Timelapse
With water diverted to irrigation, the inland Aral Sea has shrunk dramatically. Many areas were completely dry by 2009. Each frame of this timelapse map is constructed from a year of Landsat satellite data, constituting an annual 1.7-terapixel snapshot of the earth at 30-meter resolution. The Landsat program, managed by the USGS, has been acquiring images of the Earth's surface since 1972. Landsat provides critical scientific information about our changing planet.
