Infrared Aerial Photograph

This infra-red aerial photo of Scotia, Nebraska was taken from a satellite that orbited the Earth in 2010. Infrared photographs are useful for distinguishing between vegetations, waters, and lands; especially helpful for those that would appear the same shade in black and white photographs. The film used for these photographs is coated with a special emulsion that absorbs and translates areas of the magnetic spectrum outside of human eyesight. These photos make it easier for us to see landscapes more accurately, and therefore are more clearly understandable as maps.
