Abstract
Infrared line scanning, as well as false-color infrared photography, has been used on a limited research basis to determine thermal and spectral responses of the surface of the Earth. The main emphasis has been toward recognition of various surface features. In the main, this work has been sporadic and lacking in essential detail and ground experience. Only recently has infrared technology been available to scientists who are largely untrained in IR methods, so that coordinated and carefully planned experiments can be carried out. This presentation reviews some of the uses of IR line scanning and IR photographic techniques in Quaternary research. Particular emphasis is placed on IR imagery of surficial deposits and related vegetation, surface forms, groundwater discharge areas, and soil moisture anomalies. The virtues and hazards of IR methods are discussed, and recommendations are made for the future.
