B)Satellite imagery. To celebrate the sunny days of summer (in the northern hemisphere at least), today we’re launching new satellite imagery for Google’s mapping products. This stunning global view is virtually cloud-free and includes refreshed imagery in more locations—giving you an even more accurate and comprehensive view of our planet’s landscape.
C)Our satellite imagery is usually created like a quilt: we stitch together imagery of different parts of the world. Using a process similar to how we produced the global time-lapse imagery of the Earth, we took hundreds of terabytes of data from the USGS’s and NASA’s Landsat 7 satellite. Sometimes dozens of photos of a single spot in the world. And analyzed the photos to compute a clear view of every place, even in tropical regions that are always at least partly cloudy.
