Google has updated its Google Maps and Google Earth with higher quality and sharper imagery. Shot using NASA‘s Landsat 8 satellite, Google is using a new processing technique that involves mining of about a petabyte of Landsat images, and sorting 700 trillion individual pixels to get 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 explains in a blog post. The new Earth imageries are now available across all devices using Google s map services. You can see these images on Google Earth, or by simply turning on the satellite filter on Google Maps.

Earlier, Google used images from NASA s Landsat 7 satellite, which in 2003 suffered a hardware damage that resulted in gaps of missing data from the images. This made Google switch to the latest Landsat 8, which was launched in 2013. The new rendition of Earth uses the most recent data available and mostly from the Landsat 8 satellite. The new images are sharper with finer details and truer colors.
The Landsat program is a collaboration between NASA and USGC, and is available as free and accessible open data to all. Under the program, the satellites have been observing capturing images of the Earth since 1972, which can be seen on Earth Engine.
