Working with the U.S. Geological Survey (USGS), NASA and TIME, Google has released more than a quarter-century of images of Earth 
taken from space, compiled for the first time into an interactive time-lapse experience. It is believed that this is the most comprehensive picture of our changing planet ever made available to the public.
The images were collected as part of an ongoing joint mission between the USGS and NASA called Landsat. Their satellites have been observing earth from space since the 1970s—with all of the images sent back to Earth and archived on USGS tape drives that look something like this example (courtesy of the USGS).
The maps also features Growth of Las Vegas, Saudi Arabia Irrigation, Amazon Deforestation in Brazil, Drying of Aral Sea, Drying of Lake Urmia in Iran.
