Advances in applications for aerial infrared thermography

The farther away one can get from the subject of an infrared (IR) survey, while maintaining the needed spatial resolution and thermal sensitivity, the more usable the data becomes. This is the aerial IR advantage. Aerial IR applications can be divided into two groups; A) applications where a straight-down view and/or a large area view is needed and B) applications where long distances must be covered in a limited amount of time. Selection of aircraft, aircrew, navigational aids, avionics, infrared imaging system, analog and/or digital data acquisition systems and image processing systems are all important for successful surveying.
