Aerial Surveillance to Monitor Water Quality in Catfish Ponds

Remotely sensed data and ground truth data were collected simultaneously from 16 experimental ponds during 6 days in June and July, 1974. Color infrared images were taken with hand-held 35mm cameras from single engine aircraft. Numerical color values for pond color were obtained visually matching the pond color with a Munsell Color System chip which had a standardized numerical value assigned to it. Ground truth data involved the determination of 14 chemical, physical, and biological parameters. Regression analysis indicated a significant correlation (P<.01) existed only between total...
