A preliminary investigation into the use of the tarif system and three tree selection methods for obtaining Douglas-fir stand and stock tables from large-scale aerial photography

Creator:

McCadden, Richard Jay

Abstract:

As a preliminary step toward the establishment of a 70 mm. aerial photo timber inventory system capable of generating accurate stand tables, stock tables, and gross volume estimates, this project focuses on the development of a system which (1) eliminates the need to measure tree height on the photos through...

Detection of dwarf mistletoe in young-growth ponderosa pine from color aerial photography

Creator:

Hann, David W.

Abstract:

The purpose of this study was to determine if infection levels of dwarf mistletoe on ponderosa pine could be detected with color aerial photography. The photography was taken in early September using Kodak Ektachrome Infrared Aero and Ektachrome Aero films at scales of 1/4000, 1/2000, and 1/1000. Ground truth consisted...

Probability proportional to size sampling of Douglas-fir from aerial photography

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...

Multitemporal classification of vegetation in the Oregon Coastal Range using landsat multispectral scanner data

Creator:

Wang, Sen

Abstract:

The vegetation of a 420 square mile area of the Oregon Coastal Mountain Range was mapped using data from the multispectral scanner system aboard Landsat. Advantages of this mapping system include rapid synoptic coverage of the same geographic area at different periods in time at a reduced cost compared to...
