  • 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...

  • Interactive choropleth mapping using high resolution color graphics

    Creator:
    Spielman, Julie B.
    Abstract:
    A program, Color Choropleth Mapping System (CCMS), has been developed to provide high quality color choropleth maps at the Geography Department at Oregon State University. The program operates interactively and is menu-driven. When developing the software for mapping programs, programmers need to be aware of cartographic theory, as well as...

  • 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...

  • Specification of cartographic layer tinting schemes for color graphic monitors

    Creator:
    Bradbury, Jaimie L.
    Abstract:
    This study provides some guidelines using and comparing the RGB (red, green, blue), HSV (hue, saturation, value), and HLS (hue, lightness, saturation) color specification systems to help designers of computer produced layer tinted maps to select appropriate and effective colors from the immense palette provided by modern color monitors. Map...

  • 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,...

  • 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...

  • 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...

  • 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...

  • 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...
