Today we’re rolling out an even more beautiful and seamless version, with fresh imagery from Landsat 8 satellite and new processing techniques for sharper images than ever before. 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 update is courtesy of NASA’s 2013 launched Landsat 8 satellite. I’ve had a quick squizz at a couple of spots that I know I’ve looked at before and it does indeed seem quite improved.
Also if you’re interested there’s a great video on the Landsat program and why it’s so important over here.
