Creator:: Rogers, Roger Allan
Abstract:: This experiment was designed to investigate the use of volume estimations from aerial photography and probability proportional to size (PPS) sample selection in the development of a practical sampling design for timber volume estimation on small land areas of Pacific Northwest Douglas -fir (Pseudotsuga menziesii, Franco). The major problem of...

Abstract:: Evaluation of four 35 mm film:lens combinations for estimating conifer mortality showed that large-scale true color images obtained with Kodak High Speed Ektachrome and color infrared images obtained with Kodak Ektachrome Infrared, both exposed through a 135 mm lens were best. Higher correlation coefficients were found for the true color:135...
