Military was doing it in Iraq back in 09 with planes https://www.eglin.af.mil/News/Article-Display/Article/392767/angel-fire-surveillance-a-key-tactical-asset/ https://www.eglin.af.mil/News/Article-Display/Article/392767... No machine learning, but same concept. There was a constantly orbiting plane with super high-res cameras on the bottom, taking pictures of entire cities, roughly 1 picture per second. When an IED went off they could zoom in and "rewind the clock" and watch where the explosion occurred, watch the person burying the IED, how they arrived, and where they came from up to the city limits. Was apparently an invaluable tool. You'd need tunnels to defeat it. That was almost 15 years ago. I'd be shocked if a satellite version for even larger regions wasn't in the works.
