The needs and markets for aerial photography have grown
steadily with the increasing demands for improved resource
management (Kodak, 1985, 2 & Simonett, 1983, 1). Aerial
photography within the Willamette Valley could provide researchers
and professionals with a broad range of data in disciplines such as
agriculture, forestry, geology, and...
The City of Newport, in Lincoln County, is undergoing change in response to shifts in
demographics and the economic base. Following a 1990 report, a comparative growth study of the region
was initiated to observe the effectiveness of Oregon's mandatory urban growth boundaries. Data was
collected for land use permits...
Virgin aggregate resources (crushed stone, rock, sand and gravel) are the literal
foundation of America's built environment. Aggregate resources are arguably the most
abundant natural resources in the world next to water. However, land use and
environmental concerns shadow both existing and future aggregate resource sites, which
may create a...
The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...
The City of Waldport, Oregon, has been periodically exposed to the
effects of marine flooding and erosion. Consequent to the erosion of the
Alsea Bay sandspit during the fall of 1985, one Waldport residential neighborhood
was faced with the imminent threat of serious marine flood inundation.
This study includes a...
Along with the increased attention in the past two decades on the values of wetlands and the documentation of great losses of wetland acreage has been a growing need for a comprehensive assessment method for analyzing the functions of a wetland. Detailed site-specific study has been the traditional method for...
El Niflo and La Nifia are oceanographic and atmospheric phenomena that have been
catalogued for well over a centuly. In El Nifio years, Peru's otherwise thy west coast is
subjected to torrential rainfall. Higher ocean temperatures off the coast are deemed the
culprit. Attempts to quantify this began in the...
The purpose of this research was to develop methods for using geographic information system (GIS) analysis and unsupervised classification of Global Vegetation Index (GVI) images to improve carbon budget estimates of the former Soviet Union (FSU). A GIS was used to locate the geographic distribution and estimate the area of...
Agricultural land conversion is a complex process that involves a
matrix of decisions and decision-makers. This study examines the
nature and relative significance of spatial factors that influence the
decisions of farmers who either sell farmland to developers for urban
use or retain it for agricultural use. The conceptual model...
GIS and other geographic mapping tools have become an integral part of our
society for disseminating spatial infonnation to assist in making informed land planning
decisions. Disc golf is a recreation activity, most commonly found on public lands, which
utilizes the natural landscape in a manner that enhances its enjoyment....
