A per-segment approach to improving aspen mapping from remote sensing imagery and its implications at different scales

Creator:: Heyman, Ofer
Abstract:: A per-segment classification system was developed to map aspen (Populus tremuloides) stands on Winter Ridge in central Oregon from remote sensing imagery. A 1-meter color infrared (CIR) image was segmented based on its hue and saturation values to generate aspen "candidates", which were then classified to show aspen coverage according...

The effects of land use changes on forest fires in major islands of Indonesia

Creator:: Lumban-Tobing, Pago L.
Abstract:: The study examines the effect of forest clearance on fire occurrences in major islands of Indonesia, namely: Borneo, Sumatra, Sulawesi and Irian Jaya. The working hypothesis of the study is that forest clearing is a necessary predecessor for extensive fires to occur. The study is designed to test the idea...

Analysis of riparian vegetation age structure and forest land ownership in the Central Oregon Cascades

Creator:: Purnell, Christopher S.
Abstract:: Vegetation along the banks of mountain streams in the western Oregon Cascades comprises an integral part of the transition zone between land and water based ecosystems, and as such, is a vitally important and unique natural resource. Forestry is a major land use in this region, and harvesting riparian vegetation...

A Methodology to directly input data from an uncontrolled aerial photograph into a vector based geographic information system

Creator:: Sneed, Jacquelin M.
Abstract:: Historically the U.S. Forest Service has used uncorrected aerial photographs to delineate proposed and past management activities on the land base it manages. Transferring a boundary from an image not planimetrically correct to a planimetrically corrected image introduces errors. Positional accuracy of boundaries affects the number of acres the Forest...

A TM-based hardwood-conifer mixture index for closed canopy forests in the Oregon Coast Range

Creator:: Maiersperger, Thomas K.
Abstract:: The purpose of this study was to develop, implement, and test methods for quantifying the relative proportion of hardwood and conifer cover from Thematic Mapper (TM) imagery. The research was focused on closed canopy forests in the Oregon Coast Range, where hardwood, conifer, and mixed stand conditions are prevalent. Based...

A site suitability model for Acacia koa reforestation on Mauna Kea, Hawai'i, utilizing a GIS

Creator:: Splean, Scott L.
Abstract:: A site suitability analysis for reforestation of the endemic Hawaiian forest tree koa (Acacia koa var. hawaiiensis) was performed. The study will assist the Hawai'i Resource Conservation and Development's (RCD) Forestry Committee in their effort to develop a master land use plan for koa regeneration on the Island of Hawai'i....

The use of GIS in the analysis and prediction of available salmon habitat in an Oregon coastal stream

Creator:: Newton, Ann M.
Abstract:: Because of declines in salmon populations in recent years, the health of salmon habitat, in particular, is the focus of many resource agencies. The objective of this study is to use GIS to predict the location of suitable habitat. With data from an extensive set of stream surveys, GIS was...

Modeling the Environmental Protection Agency's level IV ecoregions within the Klamath Mountains of Southern Oregon and Northern California : a Geographic Information System approach

Creator:: Zanger, Christopher
Abstract:: Ecoregions are regions of relative homogeneity with respect to specific ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing awareness that effective management of environmental resources must be undertaken with an ecosystem perspective (Omernik, 1995). Ecoregions serve as a spatial framework for assessing, managing, and monitoring ecosystems that...

Multivariate thematic map visualization of the Oregon 2001 drought

Creator:: Theirl, David M.
Abstract:: The visualization of climate patterns is a major theme in cartography. Short-term dramatic weather events such as hurricanes and tornado outbreaks are mapped and displayed immediately in order to capitalize on the sensational nature of the events, and to quickly and accurately convey the information to emergency workers and the...
