I dont know about much but I know satellites. Interpreting satellite imagery is a science known as remote sensing. I use remote sensing on many satellites all over the world. Satellites are judged in bands that reflect off the earths surface, most satellites have 7-14 bands of unique light reflection tolerances. Each band has a number between 0-255, otherwise known as a spectral signature. It is based on cell wall reflection and chlorophyll absorption. As of now there is no satellite that I know of that can detect a spectral signature for weed because it is so close to other vegetation. I do studies on logging re-growth so I see many vegetation signatures. I worked with a professor and NASA on grants and he told me one time NASA asked him to do a weed project. But he rejected it because the technology isnt there. So in conclusion, watch out for the planes and choppers, but satellites shouldnt keep you up at night. And even with the thermal IR band, they cant see your indoor lights either. That is other technology. I hope this lets somebody sleep better.
