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...

Geographic Information System model rating old-growth stand significance on the Olympic National Forest

Creator:: Wettengel, William M.
Abstract:: With increased attention being focused on the remaining old-growth forest resource in the Pacific Northwest a way to ecologically rate forest stands is needed to assist the U.S. Forest Service in its management decisions. A Geographic Information System (GIS) model was developed to rate old-growth stands in a 49,500 acre...

Aspen age structure and stand conditions on elk winter range in the northern Yellowstone ecosystem

Creator:: Larsen, Eric J.
Abstract:: Aerial photographs and field sampling were used to compare aspen (Populus tremuloides) age structure and stand conditions on elk winter range in the northern Yellowstone ecosystem. The elk winter ranges studied were the northern range in Yellowstone National Park (YNP) and the Gallatin National Forest and the Sunlight/Crandall elk winter...

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...

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...

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...

Geographic information systems : some considerations for use in geographic research and analysis

Creator:: Herstrom, Andrew A.
Abstract:: The major considerations for acquiring and using a geographic information system (G..I.S.) for regional or national geographical research and analysis are examined in this paper. After defining what a G.I.S. is, some of the more practical and useful functions of a G.I.S. in day-to--day geographical work are outlined. Finally, the...

Biophysical spectral regionalization of the Pacific Northwest using Advanced Very High Resolution Radiometer Imagery

Creator:: Greninger, Jon F.
Abstract:: Satellite imagery has become an efficient and time effective tool that may aid in the development of regional terrestrial and aquatic resource management schemes. A methodology utilizing National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) imagery, 1.1 kilometer spatial resolution at nadir, was developed for delineating...

Extending the Ecosystem Management Decision Support system to enable data migration

Creator:: Crouse, Kenneth
Abstract:: In this work software is developed to take an ecosystem management tool used by the US Forest Service, the Ecosystem Management Decision Support (EMDS) system, and enhance its utility by capturing the results of an ecosystem assessment and saving them in a format that facilitates importation into other management tools,...

The effects of lineage on spatial data quality

Creator:: Blair, Brent R.
Abstract:: When the Spatial Data Transfer Standard is adopted as a Federal Information Processing Standard, a Quality Report containing sections on lineage, accuracy, logical consistency, and completeness will be required of agencies producing digital cartographic data. This Quality Report diverges significantly from the "U.S. National Map Accuracy Standards", in place for...
