some cosiderations

[Qiaozhi]

Hi J_Player,

OK - you are correct. Carl's Intro says: "The term "remote sensing" is used to describe scientifically viable methods of detecting geophysical anomalies from a distance. It is also used to describe the less scientific method of "long-range locating", which is engulfed in controversy."
I guess we've spent so much time battling with the controversial side of remote sensing that I'd forgotten the original definition.
So- does anyone really know whether this stuff works or not?
