A thermal infrared scanner (heat sensitive rather than light sensitive) has been used to map underground water routes, in an effort to prevent cracks and potholes on an air-base runway in an area with very cold weather conditions. The scanner produces black-and-white images of the area being scanned, each shade indicating the amount of heat given off by a particular object. Each shade is then color-coded to more sharply define heat differences between objects. Identification is possible through contrast between hot and cold. The thermal scanner images are run through a computer complex called the Digital Image Processing Complex for analysis. Photos from an aerial camera were subject to Special Color Analysis Techniques (SCAT) which reveals the most subtle indications of runway damage.
