The GPS antennas on the UAVs face up, and have a (not very deep) null 
facing down, so those rustic farmers are going to need a fair amount of 
power facing up...

(and besides, why do it outside, when you can inexpensively rent large 
industrial concrete tilt-up buildings with water, heavy power, and a 
loading dock..)

And, as far as remote sensing goes.. commercial overhead imagery from 
aerial photo and satellites (SPOTimage, etc) is sufficiently good to 
detect this kind of thing (as well as things like unpermitted swimming 
pools on which property tax is not being paid).
