Airborne infrared imagery and its limitations in civil engineering practice. Paper presented at the 51st Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1972.

This paper discusses specific limitations of the infrared imaging technique. Of prime interest is what infraded cannot do for the civil engineer under present state-of-the-art technology. The discussion is divided into the two general categories of geological and hydrological limitations and is based on the experience derived from operational airborne infraded imaging surveys performed since 1963. Comments are limited to information derivable by interpretation from film or positive contact prints of infraded imagery. (see also B 175)
