Feast your eyes on how the earth change from 1984 to 2020.
Over the years, Google has been working to improve the accuracy, imagery, and functionality of Google Earth so that many of us are most likely to travel the world. Today, “Google Earth” has received its biggest update in years, including a new layer: time.
The app launched a feature called “Timeline“, which allows you to understand how the planet has changed over the years, collecting millions of satellite images from 1984 to 2020.
As you can imagine, creating time-lapse images of the entire damn planet requires a lot of computing power, including a large number of images from NASA Landsat and Copernicus programs. As claimed by Google
It took more than two million processing hours across thousands of machines in Google Cloud to compile 20 petabytes of satellite imagery into a single 4.4 terapixel-sized video mosaic — that’s the equivalent of 530,000 videos in 4K resolution! And all this computing was done inside our carbon-neutral, 100% renewable energy-matched data centers, which are part of our commitments to help build a carbon-free future.
Google also collaborated with the Create Lab of Carnegie Mellon to identify five key themes of change visible in Google Earth: changing forests, evolving cities, rising temperatures, energy and the fragile beauty of planets.The company conducts touring performances for each theme.The company hopes that the timeline will give users a realistic understanding of how our planet changes over time and why we need to protect it.
To view the timeline yourself, you can go to Google Earth here.If you don’t want to look for key points, the company has added hundreds of Timelapses to this playlist.
