  • 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,...

  • 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...

  • 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,...
