Airborne videography as a classification and validation technique for Landsat TM-based vegetation mapping

Creator:: Barrett, Charley, 1965-
Abstract:: The Oregon Department of Fish and Wildlife's (ODFW) Ecological Analysis Center (EAC) is in the process of creating, from Landsat Thematic Mapper (TM) imagery, a vegetation map of Oregon that will meet the latest standards set by the National Gap Analysis Program. Since field verification is often expensive and by...

Mapping vegetation using landsat TM and ETM+ in Eritrea

Creator:: Iyob, Biniam
Abstract:: The objective of this study was to examine vegetation and vegetation change in Eritrea over a period from the mid 1980s to 2002 using satellite remote sensing, and relate observed changes to the recent history of drought and war in the region. Specific objectives were (1) to examine vegetation change...

A global scale analysis of the spatiotemporal distribution of foliar biomass for 1988

Creator:: Pross, Derek D.
Abstract:: Many ecological systems follow a seasonal cycle affecting primary production,carbon flux, and vegetative gas emissions. The seasonal variation of ecological systems are both affected by and have effects upon climatic factors. A quantitative estimate of the seasonal variation of vegetation is required to characterize ecological systems and their interaction with...

Monitoring individual particle transport in a gravel bedded stream using a passive radio transponder system, Corvallis, Oregon

Creator:: Childers, Elayne S.
Abstract:: Gathering empirical data on the factors and processes affecting bedload transport in the field is difficult. This project conducted during the winter of 1996 field tested a new passive method of positively tracking individual particle movement. The project was conducted in Oak Creek, a gravel bedded stream, located in Corvallis,...

Mapping vegetation density and water inundation in a recovering wetland : the Mesopotamian Marshlands

Creator:: Bosley, Jon Michael
Abstract:: Once considered the largest wetland in Central Asia, the Mesopotamian Marshlands of Southeastern Iraq have nearly disappeared. Various hydrological projects by the Iraqi government and dam construction in the region have nearly destroyed these once rich freshwater wetlands by over 90%. With the launching of Operation Iraqi Freedom recent attempts...

An evaluation of the resources of the Mosquitia Region of Honduras by means of Remote Sensing and GIS

Creator:: Torres, Juan Carlos
Abstract:: The Mosquitia Region of Honduras is part of the largest wilderness area in Central America. In terms of biodiversity the area is rich in ecosystems including pine savannas, tropical rain forests, and wetlands. These ecosystems are rich in millions of species including rare and endangered. Honduras faces an economic, social,...

Multi-spatial scale representation of landscape transitions using landsat thematic mapper data and scale-space filters

Creator:: Lindeman, Dale R.
Abstract:: This thesis considered current approaches to describing landscape pattern, identified scale issues associated with defining objects, and explored techniques to reliably group elements based on land cover as represented by satellite imagery. It was recognized that there is an important need to develop tools that can be applied using remotely...

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...

Measurement, modeling, and remote sensing of snow cover in areas of heterogeneous vegetation

Creator:: Selkowitz, David
Abstract:: Numerous studies have demonstrated that vegetation canopies affect snow accumulation and ablation processes. In addition, estimates of remotely sensed snow covered area can be biased by the presence of an overlying vegetation canopy. Consequently, any attempts to measure, model, or map the distribution of snow in a region with heterogeneous...

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...
