Is that insider trading?
Everything you listed is publicly accessible knowledge (there is an interesting conversation over the fact that a poor person is unlikely to have the available means to attain this information) and I think should be fair game. But I really have not done the legal research to confidently give you a “Yes” and willfully will exit so I don’t get some SEC agent knocking on my door.
This was old enough to be the stuff of office legends fifteen years ago. (Also, flying drones to thermally image petroleum tankers to infer their levels.)
But if it's that easy that means other people are already doing it and you probably can't make any money.

The general term for this stuff is "alternative data".
