look at these green dots in the middle of the desert (this is a satellite image of the landscape in egypt btw).
how come? do they use some kind of sprinkler system or sth? does anybody have the name of this type of setup, or any close-up photographies?
Its a lot more cost effective to have one long boom arm sweep out a radius with a wheel at the end. Basically some of the most heavily optimized for and well supplied irrigation systems on the planet.
