) Our most detailed view of Earth across space and time – Earth
In 2013. We released Google Earth Timelapse. Our most comprehensive picture of the Earth’s changing surface. This interactive experience enabled people to explore these changes like never before to watch the sprouting of Dubai’s artificial Palm Islands. The retreat of Alaska’s Columbia Glacier. And the impressive urban expansion of Las Vegas, Nevada. Today. We’re making our largest update to Timelapse yet. With four additional years of imagery, petabytes of new data. And a sharper view of the Earth from 1984 to 2016. We’ve even teamed up again with our friends at TIME to give you an updated take on compelling locations.

B) Our most detailed view of Earth across space and time
Leveraging the same techniques we used to improve Google Maps and Google Earth back in June. The new Timelapse reveals a sharper view of our planet. With truer colors and fewer distracting artifacts. A great example of this is San Francisco and Oakland in California:

There’s much more to see. Including glacial movement in Antarctica, urban growth. Forest gain and loss. And infrastructure development:.

Using Google Earth Engine. We sifted through about three quadrillion pixels that’s 3 followed by 15 zeroes from more than 5,000,000 satellite images. For this latest update. We had access to more images from the past, thanks to the Landsat Global Archive Consolidation Program. And fresh images from two new satellites. Landsat 8 and Sentinel-2.
Our most detailed view of Earth across space and time
We took the best of all those pixels to create 33 images of the entire planet. One for each year. We then encoded these new 3.95 terapixel global images into just over 25,000,000 overlapping multi-resolution video tiles. Made interactively explorable by Carnegie Mellon CREATE Lab’s Time Machine library. A technology for creating and viewing zoomable and pannable timelapses over space and time.
