  • 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...

  • 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...

  • 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...

  • Terrain analysis and Geographic Information Systems

    Creator:
    Bruzese, Victoria M.
    Abstract:
    The purpose of this paper is to define terrain analysis, as it relates to military applications; to review the historical development of the central ideas of terrain analysis, which has led to the development of three computer programs that are designed to make terrain analysis an automated process rather than...

  • 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...

  • Spatio-temporal pattern analysis of managed forest landscapes : a simulation approach

    Creator:
    Li, Habin
    Abstract:
    This study dealt with research problems at the landscape level. The objectives of this thesis were to develop tools to study and characterize landscapes and to interface with a geographic information system (GIS), to evaluate landscape indices, and to examine development of forest cutting patterns under different cutting methods and...

  • 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...

  • Using a Geographic Information System to identify and reduce uncertainty in hydroelectric-site inventories

    Creator:
    Ellison, Bradley A.
    Abstract:
    Power planning efforts in Oregon require accurate information about hydroelectric potential. Potential uses for Geographic Information Systems (GISs) are being investigated by three Oregon planning agencies. This paper presents a method in which a 616 is used to help identify and reduce uncertainty in previous hydroelectric inventories. Uncertainty with respect...

  • Soil erosion assessment in the Republic of Cape Verde, West Africa, using a geographic information system

    Creator:
    Gomez, Sharon N.
    Abstract:
    Soil erosion is a natural physical process. However it can become a detrimental force when factors such as infertile soils, steep topography and poor farming practices are combined. An important initial aspect of resource planning and/or soil conservation involves locating areas where such potentially hazardous combinations occur in the field....
