Google Maps and Earth get refreshed satellite imagery

Google is updating all of its mapping products today with brand new, cloud-free satellite imagery from space that it says “includes refreshed imagery for regions of the world where high-resolution imagery is not yet available, and offers a more comprehensive and accurate view of the texture of our planet’s landscape.”

With the Blue Marble as inspiration, we used Google Earth Engine technology to mine hundreds of terabytes of data from the USGS’s and NASA’s Landsat 7 satellite. The result is a seamless, globally-consistent image of the entire planet with a resolution of 15 meters per pixel, far finer than is possible with MODIS data alone.
