Abstract : Spectral reflectance measurements made with a trailermounted Beckman DK-2A spectroreflectometer near Dexter, Michigan, in August 1963, are presented. Curves of foliage reflectance in the 350- to 2,750-millimicrons wavelength range are included. Predicted tonal contrasts based on the reflectance data were compared with panchromatic and infrared aerial photographs of the study area. Actual results agreed with predicted tonal contrasts except for needled trees which appeared darker-toned on the infrared photography than had been predicted. (Author)
