Equal value gray scales are frequently employed by cartographers to choose gray tone area
symbols. Several researchers have tried to quantify perceived gray tone as a function of percent area inked or
reflectance but results have varied. The influence of pattern and texture on gray tone perception is considered
a...
Slope-aspect is the compass direction of a slope at a particular location on a given
surface, and can provide a graphic tool for people who require an understanding of
the pattern of slope-aspect variation across a landscape. Slope-aspect maps can be
helpful for terrain analysis, watershed management, building site analysis,...
The main purpose of this research is
1. To analyze the terrain/climate of Cape Verde, with emphasis on cloud
cover, and its effect upon satellite image acquisition.
2. To use a methodology that allows the use of AutoCAD to map these clouds effect in image acquisition to permit viewing whatever...
Tourism has become an important factor in Oregon's and
New Zealand's economies. Both destinations are trying to
attract even more tourists. However, many other destinations
are also competing for a bigger share of the tourism market.
Tourism itself is a multi-faceted phenomenon and the travel
destination decision is of some...
"Final report to the U.S. Environmental Protection Agency. Funds supporting this study have been provided by Region 10 of the U.S. Environmental Protection Agency, Seattle, WA."
The middle to upper Eocene Tillamook Volcanics form the basement in the Rock Creek - Rocky Point area. These tholeiitic to alkalic basalts, basaltic andesites, and andesites were erupted as shield volcanoes seaward of the strandline ontop of an older deep-marine mudstone unit (Yamhill Formation) and an accreted portion of...
The American Proposed Standard for Digital
Cartographic Data presents the new national exchange format
which allows the transfer of spatial data among parties
that may use different computer hardware and different
operating system software.
A translator program for the conversion of the AutoCAD
DXf data structure to the Standard's output...
Eleven sedimentary and volcanic rock units are mapped and described in the thesis area, and chronicle the dynamic geologic history of the Tillamook embayment from the Oligocene through the middle Mlocene. The
oldest unit is the Zemorrian to early Saucesian Smuggler Cove formation, a bathyal tuffaceous mudstone with some thin-...
Both travel times and amplitudes of large offset refracted and reflected arrivals
observed during GLIMPCE (Great Lakes International Multidisciplinary Program on
Crustal Evolution) along line A in Lake Superior have been modeled using two-dimensional
ray tracing techniques. Forward modeling was used to iteratively refine an
initial velocity model that was...
A site suitability analysis for reforestation of the endemic Hawaiian forest tree koa (Acacia koa var. hawaiiensis) was performed. The study will assist the Hawai'i Resource Conservation and Development's (RCD) Forestry Committee in their effort to develop a master land use plan for koa regeneration on the Island of Hawai'i....
