When it comes to smartphones, upgrades are made to their internal components – more powerful processors backed by more RAM, screens with higher resolution and bigger batteries. Google is also upgrading its satellites and recently, the company has announced that users are now getting stately imagery from Landsat 8 and their resolution has been increased thanks to a new image processing technique.
There are many people who use either Google Maps or Google Earth on a daily basis and they’re looking for places to visit or for business purposes and they need to see high quality images of those locations. Google has finally decided to invest more money on improving satellite imagery for the desktop web mapping service and virtual globe, map and geographical information program. From now on, users will enjoy an “even more beautiful and seamless version” of the Earth mosaic. In the official announcement, Google has explained that “Satellite images are often cloudy, but not always over the same place, so we looked at millions of images and took the clearest pixels to stitch together this cloud-free and seamless image.” The results are amazing.
It is known that Google has launched the Landsat 8 satellite back in 2013, when it was getting ready to update its Landsat 7 imagery because of those stripe artefacts and because the resolution was very low: 1 pixel for every 15 meters. So far, Google hasn’t specified the new meters-to-pixel ratio and we haven’t checked how sharp satellite images are now in Google Maps and Google Earth.
The company has noted that the result was achieved by using 700 trillion pixels of imagery, and astronomy fans will be happy to hear that’s 7,000 times more pixels than the estimated number of stars in the Milky Way, and which is 70 times more pixels than the total number of galaxies in the universe.
