"couldnt someone just attach a gpr system to a plane?"

That's exactly what's driving a lot of new archaeological scholarship in jungle areas. It's not as simple as "just" though, it takes money and time and effort.

and don't forget local buy-in. can't just drop down on a plane on people and start hacking away their forest (anymore)
