alt Hacker NewsIt must be quite valuable data. One anecdote I heard/read somewhere was that firms often use satellite imagery of parking lots (over time, as one measure among others) to gauge how popular a place is. I don't know if it's true or not.

Similarly, I listened to a talk from someone who used to perform analysis of aerial images of farmland to estimate yields at harvest, which would then be used to trade in the futures market.
It's true and they go a lot further hunting signals that people without their resources simply can't.

They have the resources to spend (to them) a small amount to confirm/check a play before they make it, it's been a thing since commercial satellite imaging became a thing.
Hell the (somewhat terrible but somehow enjoyable) TV show Billions had it as a plot point years ago.
