My guess is that there is no such thing available. The images on google earth were taken over a period of many, many days (by airplanes as well as satellites). In order to take pictures of the resolution you see on google earth, the camera has to zoom pretty far in, which means it will see only a small patch of land each time it passes over, which means it must make many passes in order to build up a catalog of photos of the whole earth, which takes days and weeks and months to complete.

Also, satellites that are close to the earth (where they would have a good view) are moving very fast (because of the laws of gravitation). That means any given spot on the earth will only be within the satellite's view for about 5 minutes at a time; and it's usually hours or days before it passes over that same spot again.

Other satellites have a constant view of the entire country, but they are about 100 times as far away (about 22,000 milies), and it would be astonishing if they could take photos with very good detail from that distance. To take a photo of the whole US with enough detail to see individual houses, would require something like a 100,000 Megapixel camera(!)

Such feats are only possible for Jack Bauer and the CTU team.
