Travel in time to check global heating
How has your neighborhood changed over the last 37 years and does global heating mean that icy parts of our planet are less icy now then they were in 1984? Google Earth has added 24 million satellite pictures covering the last 37 years offering users to see how locations have changed over time.
The company says it’s the biggest change for years and called Timelapse in Google Earth, with the millions of satellite photos from the past 37 years added to an interactive 4D. Locations can be searched as for Google Earth in general – g.co/Timelapse.
Carnegie Mellon University’s Create Lab has created the technology behind Timelapse.
Google said the 24 million satellite images from 1984 to 2020 represent quadrillions of pixels. 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.
“As far as we know, Timelapse in Google Earth is the largest video on the planet, of our planet. And creating it required out-of-this-world collaboration”, Google said mentioning the U.S. government and European Union’s commitments to open and accessible data.
“In collaboration with our partners, we’ll update Google Earth annually with new Timelapse imagery throughout the next decade. We hope that this perspective of the planet will ground debates, encourage discovery and shift perspectives about some of our most pressing global issues.”
