Is Google Satellite Map taken by satellite or synthesized by computer? Are Japanese cameras the most advanced in the world?

Google Maps is a combination of many technologies, including direct satellite photography and computer-generated images. You know, at least so far, it is impossible for a camera to shoot a three-dimensional image directly, and the three-dimensional image always has to go through some technical processing. In other words, those three-dimensional images are processed by computer based on photography.

As for camera technology, Japanese cameras may be the first on land, but so far the technology of space cameras in the United States is higher. Americans have the highest resolution spy satellite in the world, with a resolution of centimeter (it is reported that the resolution of the new spy satellite in the United States can reach15cm), while the second resolution satellite in the world was launched by India in July this year, and nothing happened to the Japanese.
