Physical-biological interactions in the Southern Ocean were investigated using remote sensing data from several different satellite sensors. Satellite sea surface temperature data were used to study the dynamics of the Antarctic Polar Front (PF). Satellite ocean color data were used to estimate surface chlorophyll concentrations and their relation to various...
Forest and wildlife habitat analyses were conducted
at the H.J. Andrews Experimental Forest in the Central
Cascade Mountains of Oregon using remotely sensed data and
a geographic information system (GIS). Landsat Thematic
Mapper(TM) data were used to determine forest successional
stages, and to analyze the structure of both old and...
Most conventional approaches to rating turf color for different turf varieties grown
under similar conditions or for the same variety grown under different cultural conditions
employ a visual subjective rating. By digitizing remotely sensed images acquired by use
of a helium filled blimp and a Canon EOS camera, we were...
Vertebrate diversity was modeled for the state of Oregon using a parametric approach to regression tree analysis. This exploratory data analysis effectively modeled
the non-linear relationships between vertebrate richness and phenology, terrain, and climate. Phenology was derived from time-series NOAA-AVHRR satellite imagery for
the year 1992 using two methods: principal...
Previous difficulties mapping tropical forest successional stage with satellite imagery may be one of the reasons why little is known about what socioeconomic and biophysical factors control tropical secondary forest pattern over landscapes. Additional remote sensing challenges occur in regions with steep topography, because the spectral responses of land covers...
The purpose of this thesis is to apply the wavelet transform WT to
multiresolution structures for analyzing the information content of images based on
multiresolution signal decomposition of the wavelet representation. The advantage
of the wavelet transform is the fact that it uses different building blocks than the
Fourier's sines...
The purpose of this pilot program was to determine whether or not forward looking infrared (FLIR) videography could be used to develop thermal maps of the mainstem Klamath River to access habitat limitations due to high stream temperatures for fall chinook salmon (Oncorhynchus tshawytscha).
This report is organized into four chapters that provide background on watershed
topics, GIS applications, and methodology related to development of the TBNEP
Watershed Information System. The need for this product is established in Chapter two.
First, the role of ecosystem management and the Tillamook Bay watershed is presented
before...
