Abstract
Method and apparatus for determining the presence and identity of predetermined gases in the atmosphere such as would be found on a natural gas, natural gas liquid or oil pipeline if such pipeline was subject to leakage. An infrared transmitter and an infrared receiver are each mounted on a movable platform such as a fixed or rotary wing aircraft or on a vehicle. As the moving platform follows its predetermined assigned route, the presence of gases is determined by the infrared transmitter and receiver and at least one data acquisition module. The geographic position of the movable platform is determined so that the geographic location of the predetermined gases in the atmosphere is known.
