Explore a global timelapse of our planet, constructed from Landsat satellite imagery. 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.
