5 cm resolution: This is the resolution known within the limits of spy satellites, according to tech expert Nooria Khan.

The image slightly less pixelated, but the details are still indiscernible. 25 cm resolution: This is the best publicly available resolution for satellites.50 cm resolution: This is the most common resolution used in Google Maps.
