Remote sensing science is considered a new science of the 20th century, where it was introduced initially in response to a sharp demand for it during the 1st and 2nd World Wars. They were used initially for military purposes, including reconnaissance and detection of the movements of groups of soldiers and identification of the topography of the land in order to develop detailed military plans. The most known spying military program was the American CORONA program, which used to photograph sensitive areas around the world with an accuracy of 2 meters during the period from 1960 to 1972. The said program was uncovered only in 1995 when more than 800 thousand aerial photos were made available for civilian use to allow scientists, specialists and researchers in the various fields to study, analyse and use them
