Remote sensing is one of the economical, practical, and fast technology, which is used to sense and detect surface and ground mineral treasures such as gold, silver, bronze, etc. It is also used for detecting oil, natural gas, and groundwater. Remote sensing is a science and art used to study, monitor, and detect specific phenomena, area, or object for the sake of determining the state, quantity, location, depth, and quality of this phenomena, area, or object without direct physical contact via analyzing their reflected electromagnetic spectrum (Figure 1).
