  • 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...

  • 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...

  • 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...

  • 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...

  • Epsilon, generalization and probability in spatial data bases

    Creator:
    Honeycutt, Dale M.
    Abstract:
    Cartographic generalization results In locational Inaccuracies of the generalized feature. The cartographer expresses the amount of generalization and the locational inaccuracy of the feature through map design and choice of map scale. This information is often lost when the map is digitized. In the environment of geographic Information systems, the...

  • 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,...

  • Determination of geographic information system database characteristics : an application of the information integration theory

    Creator:
    Brooks, Kris
    Abstract:
    The development of a geographic information system (GIS) requires the development of large databases of spatially related information. Scale, resolution and the classification of thematic data can vary considerably in terms of the level of detail at which the data are compiled and converted to machine readable form. The level...

  • Identification of irrigation practices using photographic and optical-mechanical scanning remote sensing techniques

    Creator:
    Naim, Shamim
    Abstract:
    Irrigation is essential for profitable agriculture in the western United States. It is the largest consumer of water and power in Oregon. Conflicting uses of water and power and their scarcity demands judicious planning for allocation of these resources. Creditable baseline data are not only needed for irrigated crop acreages,...

  • Geographic information systems : some considerations for use in geographic research and analysis

    Creator:
    Herstrom, Andrew A.
    Abstract:
    The major considerations for acquiring and using a geographic information system (G..I.S.) for regional or national geographical research and analysis are examined in this paper. After defining what a G.I.S. is, some of the more practical and useful functions of a G.I.S. in day-to--day geographical work are outlined. Finally, the...

  • A comparison and contrast of pcARC/INFO vs. AutoCAD

    Creator:
    Smith, Pamela Ann
    Abstract:
    This paper explores the confusion that exists between general definitions of what constitutes a GIS or CAD system. Then a comparison and contrast is made of microcomputer versions of GIS and CAD programs using as examples two of the most popular, pcARC/INFO and Aut0CAD. The differences and similarities are discussed...
