It 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. | ||

It's true and they go a lot further hunting signals that people without their resources simply can't. https://www.financial-news.co.uk/how-hedge-funds-are-using-s... https://edition.cnn.com/2019/07/10/investing/hedge-fund-dron... 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. | ||

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. | ||
