The influence of map complexity on interpolation accuracy.pdf

Creator:: Young, Brian K.
Abstract:: In this paper "map complexity" refers to the inherent intricacy of a mapped geographic pattern. Map complexity and sample size are two variables shown to influence the accuracy of interpolated dasymetric maps. An automated experiment was designed to investigate the precise relationship among map complexity, sample size, and the accuracy...

Equal contrast tint progressions for computer cartography

Creator:: Bernert, Joseph A.
Abstract:: A psychophysical bisectioning experiment was performed to evaluate equal steps within tint progressions on a high resolution graphics terminal. In the bisectioning experiment each respondent partitioned a tint progression by interactively defining colors that were perceptually equidistant between two previously defined colors. Twenty test subjects performed the test on the...

A Methodology to directly input data from an uncontrolled aerial photograph into a vector based geographic information system

Creator:: Sneed, Jacquelin M.
Abstract:: Historically the U.S. Forest Service has used uncorrected aerial photographs to delineate proposed and past management activities on the land base it manages. Transferring a boundary from an image not planimetrically correct to a planimetrically corrected image introduces errors. Positional accuracy of boundaries affects the number of acres the Forest...

Accuracy of community-based spatial data collection in a GIS

Creator:: Wood, Matthew N.
Abstract:: 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...

Color specification and cartography: a comparison of the Munsell Color System and the HLS system

Creator:: Yeaple, Anne
Abstract:: Progress in the development of color CRT's and color graphic hard-copy devices offers a new tool for the thematic mapper. From a cartographic perspective, the technology for displaying and producing color maps has advanced without concern for cartographic principles and conventions in the employment of color. Since it is necessary...

Expert systems in computer cartography

Creator:: Ulshoefer, Veit Stefan
Abstract:: The purpose of this paper is to describe the application of expert system concepts to cartographic problems. Expert systems, a subfield of artificial intelligence, are computer programs based on knowledge and symbolic reasoning. The basic principles of expert systems will be explained. Areas of cartography that are most suitable for...

The development of a Geographic Information System (GIS) for the Greenbelt Land Trust of Corvallis, Oregon

Creator:: Scarlett, Desiree
Abstract:: The purpose of this project, therefore, is to develop a GIS for a small geographical area that is currently of high priority to the GLT. The development of this GIS will be documented in a sequential fashion, so that it may serve as a framework for future endeavors. This paper...

Digital slope-aspect display using nearly continuous hue classes

Creator:: Weston, Frederick N.
Abstract:: 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,...

Geographic Information System model rating old-growth stand significance on the Olympic National Forest

Creator:: Wettengel, William M.
Abstract:: With increased attention being focused on the remaining old-growth forest resource in the Pacific Northwest a way to ecologically rate forest stands is needed to assist the U.S. Forest Service in its management decisions. A Geographic Information System (GIS) model was developed to rate old-growth stands in a 49,500 acre...

Production of an animated cartography sample for teaching and instruction, with musings on the nature and usefulness of animated maps

Creator:: Whaley, Kristine A.
Abstract:: Animated cartography is still a new field. It has been experimented with for years, but it has not gained general usage except partially in use by the news media. Nevertheless, certain subjects cry out for displaying the patterns of movement over time, such as historical patterns of migration and settlement,...

Multivariate thematic map visualization of the Oregon 2001 drought

Creator:: Theirl, David M.
Abstract:: The visualization of climate patterns is a major theme in cartography. Short-term dramatic weather events such as hurricanes and tornado outbreaks are mapped and displayed immediately in order to capitalize on the sensational nature of the events, and to quickly and accurately convey the information to emergency workers and the...

The affect of pattern on gray tone area symbols: a psychophysical experiment

Creator:: Selle, Anthony R.
Abstract:: 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...

An inventory of Oregon county land use maps with recommendations for future standardization

Creator:: Batch, Donna Jeanne
Abstract:: An inventory of existing land use maps developed by Oregon county planning departments has been made through use of questionnaires and interviews. The degree of consistency has been examined with regard to the types of base maps, scales, projections, base information, and classification schemes employed. Recommendations have been made for...

Hypermedia: potential for storing, managing and communicating natural resource information

Creator:: Barrington, Mack R.
Abstract:: Efficient management of natural resources requires the ability to utilize and integrate information. The challenge is to fully utilize this information base with its various degrees of accessibility, ever increasing volume and dispersed nature. The manager must be familiar with media types used to store, manage and communicate this information....

An application of photogrammetric techniques to the measurement of historic photographs

Creator:: Strausz, David A. Jr
Abstract:: The application of the collinearity solution by resection of the interior and exterior orientation parameters of historical photographs is investigated. The spatial coordinates of seven or more identifiable control points in the field of view of an historical photograph, combined with image coordinates of the control point images, allow solution...

Perception of Munshell chromas for computer-assisted map design

Creator:: Katz, Leslie E.
Abstract:: For many years, psychologists have studied the principles of psychophysics. Recently, cartographers have been considering psychophysical theory in color attribute analysis to aid in the design of maps. An experiment was conducted using the partitioning method by which the Munsell value scale was determined to find (R,G,B) coordinates giving equally...

The use of GIS in the analysis and prediction of available salmon habitat in an Oregon coastal stream

Creator:: Newton, Ann M.
Abstract:: Because of declines in salmon populations in recent years, the health of salmon habitat, in particular, is the focus of many resource agencies. The objective of this study is to use GIS to predict the location of suitable habitat. With data from an extensive set of stream surveys, GIS was...

Volcanic vulnerability : Determining the relationship between urban proximity to volcanoes and human development

Creator:: Hogue, Jennifer A.
Abstract:: Many studies have looked at human settlements around individual volcanoes for volcanic risk analyses, but few have done a comparative study to identify possible global patterns. With the use of Landsat ETM+ data, this study identifies and compares urban proximity to the Decade Volcanoes to identify volcanic settlement patterns. These...

From myth to reality: mapping the Northwest 1790 to 1850

Creator:: Mathewson, Sandy
Abstract:: The prevailing image of the Northwest at the beginning of the nineteenth century, as portrayed on maps published at the time, was based more on myth and wishful thinking than on geographic fact. During the next fifty years these myths were exploded as exploration of this previously unknown territory progressed,...
