Remote sensing in a water-resources study of Yellowstone National Park, Wyoming, Montana, and Idaho

This report describes the usefulness of remote-sensing data in a water-resources study of Yellowstone National Park by delineating warm and cool ground-water areas. Remote-sensing data from aircraft missions in August 1966, September 1967, August 1969, and May 1970 were compared with reconnaissance, ground-temperature surveys, and test-hole data. Thermal-water discharge areas can be determined from infrared imagery and photography from the aircraft missions. Contrasts on infrared imagery caused by differences in vegetative cover, particularly between forested and nonforested areas, often mask the effects of ground-water temperature differences. The imagery, however, shows relatively warm and cool land surface in some areas. Color and color infrared photographs have been useful in reconnaissance.
