US: Search engine giant, Google has rolled out an update of the satellite imagery for both Google Maps and Google Earth. The company has added more detail and better colours to both these apps. Using the Landsat 8 satellite which was launched in 2013, images are captured with greater detail, truer colors, and at an unprecedented frequency—capturing twice as many images as Landsat 7 does every day.
This new rendition of Earth uses the most recent data available mostly from Landsat 8 making it the freshest global mosaic to date. Google says the map was compiled from “nearly a petabyte of data,” mining over 700 trillion individual pixels to find the best cloudless images to use. You can see the new and improved service now in both apps — just remember to turn on satellite images for Google Maps.
In a blogpost Google said, ‘Landsat 8 captures images with greater detail, truer colours, and at an unprecedented frequency—capturing twice as many images as Landsat 7 does every day.’
‘Like our previous mosaic, we mined data from nearly a petabyte of Landsat imagery—that’s more than 700 trillion individual pixels—to choose the best cloud-free pixels. To put that in perspective, 700 trillion pixels is 7,000 times more pixels than the estimated number of stars in the Milky Way Galaxy, or 70 times more pixels than the estimated number of galaxies in the Universe,’ Google added.
