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

Though inconsistent with many economic
standards for resource policy, the Mining Act of
1872 is still a valid management priority on
federal lands throughout the western U.S. When
the Law was enacted, its stated objective was to
promote private development of federally held
minerals. However, the Act's free access
provisions,...
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...
The portion of the Oregon coast extending from Cape Blanco south into California has long been recognized as a distinct physiographic region, with probable ramifications for prehistoric subsistence and settlement patterns. Several researchers have proposed models outlining a greater reliance upon marine/littoral resources among groups within this region, while more...
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....
Loss of anadromous and resident fish habitat has become
an increasing concern in the Columbia River Basin. Forest
management practices play a role in the health of headwater
stream habitat. The effects of instream large woody debris
is known to effect stream morphology and fish habitat. This
paper considers effects...
This research questions the effectiveness of newspapers as a
vehicle of environmental information by determining whether the
public attitude in Alaska towards off-shore oil exploration was
consistent with that expressed in the local newspapers. All
newspaper articles about off-shore oil exploration published in
Alaska between 1980 and May 1987 were...
