A picture of Earth through time
May 9, 2013
Today, we're making it possible for you to go back in time and get a stunning historical perspective on the changes to the Earth’s surface over time. Working with the U.S. Geological Survey (USGS), NASA and TIME, we're releasing more than a quarter-century of images of Earth taken from space, compiled for the first time into an interactive time-lapse experience. We believe this is the most comprehensive picture of our changing planet ever made available to the public.
Built from millions of satellite images and trillions of pixels, you can explore this global, zoomable time-lapse map as part of TIME's new
Timelapse
project. View stunning phenomena such as the sprouting of Dubai’s artificial Palm Islands, the retreat of Alaska’s Columbia Glacier, the deforestation of the Brazilian Amazon and urban growth in Las Vegas from 1984 to 2012:

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

We started working with the USGS in 2009 to make this historic archive of earth imagery available online. Using
Google Earth Engine
technology, we sifted through 2,068,467 images—a total of 909 terabytes of data—to find the highest-quality pixels (e.g., those without clouds), for every year since 1984 and for every spot on Earth. We then compiled these into enormous planetary images, 1.78 terapixels each, one for each year.
As the final step, we worked with the CREATE Lab at Carnegie Mellon University, recipients of a
Google Focused Research Award
, to convert these annual Earth images into a seamless, browsable HTML5 animation. Check it out on Google’s
Timelapse
website.
Much like the
iconic image of Earth from the Apollo 17 mission
—which had a profound effect on many of us—this time-lapse map is not only fascinating to explore, but we also hope it can inform the global community’s thinking about how we live on our planet and the policies that will guide us in the future. A special thanks to all our partners who helped us to make this happen.
