Evaluation functions in aerial image segmentation

Creator:: Langford, William T.
Abstract:: Remote sensing is the most practical way to acquire large amounts of land cover data for monitoring and understanding environmental change, so it is important to be able to map land cover from imagery. Maps defining land cover patches as polygons rather than pixels greatly improve processing efficiency in models...

Evaluation of 35mm vertical aerial photography for estimating tree mortality

Creator:: Williams, Ralph E. and United States. Forest Service. Northern Region. State & Private Forestry
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...

Color infrared aerial photography for root disease detection in the Northern Region

Creator:: Williams, R. E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: "Holes" with dead, dying, and downed trees in the forest canopy could be reliably identified on 9- by 9-inch Kodak Ektachrome Infrared Aero film 2443 as root disease centers. Film scales larger than 1:4000 were best for detection of these "holes." Most commonly occurring causal organisms in root diseased trees...

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...

Testing two applications of image analysis for use in species-independent biomass equations for western Oregon forests

Creator:: Gray, John Edward, 1946-
Abstract:: Remote sensing technologies have proven useful and cost-efficient for quantifying various forest vegetation characteristics over multiple scales. However, significant limitations were encountered in each of two related experiments conducted to explore their potential to supplement or replace traditional, single-species biomass equations for estimation of ground vegetation and tree overstory on...
