Alternatively, such information is available, but the system that produces it is classified so the data is not released. The surface area of the Earth is 1.7e14 square metres, so it would be feasible to cover the earth with pixels to a resolution of a square metre. Each uncompressed whole earth image would be less than a Petabyte at 32 bits per pixel. Add compression and deep pockets and it would be possible to create and store whole Earth movies.
