The magnitude of global AIS data exceeds the capability of conventional in-browser graphic rendering technologies like Scalable Vector Graphics (SVG) and Canvas. Normal practices of rendering AIS data in browser will either suffer from low frame rates or will have to limit the total number of visual elements. In this...
In 1994, with the approval of the Northwest Forest Plan, the livelihood of individuals in the surrounding communities of the Siuslaw National Forest and Siuslaw Watershed were further impacted by already diminished traditional timber practices. In 2003, the United States Forest Service developed an innovative program, stewardship contracting, aimed at...
The following pages will accomplish several tasks. First, the marsh subtypes described by Jefferson as used in the map legend will be outlined and critiqued. Second, the techniques used in the OCC & DC mapping will be discussed and consequent map overlays will be presented which depict the errors in...
American Indians presently face health risks posed by exposure to environmental pollutants through different exposure routes including: inhalation (e.g., air particles), ingestion (e.g., fish, water), and dermal contact (e.g., contact with water, soil). Geographic Information Systems (GIS) are increasingly being used in the Environmental Health arena as a tool for...
This study seeks to determine the correlation between changes in statewide land use planning policies and the resulting periods of high or low urban growth in the Willamette Valley, Oregon using automated classification methods and freely available satellite imagery. To protect its farms, forests and open spaces, Oregon became the...
Despite a relative decline in the size of Oregon's
sheep industry, the problem of sheep depredation remains
a serious economic and environmental dilemma in need of
objective examination and innovative solutions. An investigative
report on the problem as it occurs in Benton County
can contribute to the information required to...
The annual growth rate for the Corvallis-Benton County
area has traditionally been higher than the growth rate for the
State of Oregon. Corvallis is considered to be one of the most
densely settled communities in the state. Since 1972, Corvallis
has experienced a drastic decline in the number of housing...
Training high school students to conduct field mapping and data
collection of wildlife habitat on public lands produces important data for
local government geographic information systems and introduces students
to the field of geography. However, the positional accuracy of the spatial
data is important for use in a GIS, as...
Field Automation is an evolving set of geographic information system
(GIS) technologies, including mobile computing and the global positioning system,
addressing operational and environmental applications in the field. This research
involves designing, developing, implementing, and evaluating an environmental and
facility application field automated GIS. The Camp Rilea National Guard base,...
