They have sub meter accuracy on their constellation to which is pretty wild. US military satellites have ~10cm accuracy in a targeted location and Google’s internal data varies from 2m to 20m depending on location. The higher res stuff is usually still from drones or aerial imagery (cameras strapped to planes that are then used to build an orthograpic image, which is why there’s weird distortion in some places).
