Yes, but it's not like every patch of land is monitored at all times. A satellite can only point it's camera at one place at a time.

- mittermayr 13y agosurely so, but in the odd case that even one single image might have a plane on it, on the path the OP currently discusses here, might be enough to confirm further travel. the full step-by-step transition of the plan wouldn't even be necessary. just one shot with that plane. from somewhere.
- Piskvorrr 13y agoGlobal? Likely. Realtime? We're not quite that far into the future. Just try and estimate the bandwidth for the biggest security camera of all times: at 1-3 meters resolution per pixel, worldwide, that's a lot of pixels (about 510 072 000 000 000 per frame, give or take - that comes out at about half an exabyte per frame, if I'm not mistaken). Take ten of these, and you've generated as much data as the whole Internet does in a day. Oh, and you also need to store it somewhere, but this is a minor issue (in comparison to the above).
