Infrared aerial photos are a type of remote sensing map type, which involves the detection and measurement of radiation of different wavelengths reflected or emitted from distant objects or surfaces. Aerial photographs can be divided based on the film type, and photographic film can be coated with different light-sensitive emulsions, each sensitive to specific wavelengths of electromagnetic radiation. Infrared emulsion is sensitive to wavelengths that fall outside the range of human vision. IR film is used most often to produce color-infrared photos, and uses false color since we can't really see the wavelengths recorded on the infrared film. The above photo is an infrared aerial photo because the IR imagery here uses false color to produce the color-infrared photo. This is due to the fact that the infrared emulsion is sensitive to wavelengths that the human eye can't see.
