点状、线状和面状地图符号数学定义的研究

Mathematical Definitions of Point,Line and Area Symbols in Cartography

    摘要
  • 摘要: 根据集合论和拓扑学的有关理论,导出了点状地图符号、线状地图符号和面状地图符号的数学定义。阐述了图形和背景的相互依存关系以及它们在传输地理信息中的整体功能

     

    Abstract: This paper studies the mathematical definitions of point,line and area symbols in cartography according to the set theory and topology.A figure is composed of point and line cartographic symbols and it is the main body of map.The ground is composed of area cartographic symbols.The figure and ground play the whole function in the transmission of geographical information.
