The above illustration as many know signifies an aerial infrared view and is used from an aerial point of view such as from a satellite, plane, or other devices, to view the ground surface. In doing so however electromagnetic radiation with a wave length longer than visible light is utilized and it is used even by the military as well for systems such as sonar. Above is an illustration of trees in a geographic region and certain colors give off different colors when the infrared factor is included in the equation (trees now pink as opposed to green).
