| 摘 要： | 城市交通网络规模的不断扩大使得交通线路图成为一种常用地图。为了提高信息的传输效率,更好地保证图形的清晰易读性,出现了变形交通线路地图1]。本文分析了变形交通线路图特性并对其自动制作过程进行了总结。为解决制作过程中地图符号冲突问题,提出了作用力驱动站点位移的交通线路图变形压缩方法。建立交通线路图中站点受力移动模型并设计了以坐标轴为轴心的移位算法。试验表明,该算法能够有效解决地图符号冲突问题,为完全自动制作变形交通线路图建立了基础。

| Abstract: | The traffic route maps have become common for the expansion of urban transportation networks. In order to improve the information transmission efficiency and better ensure the clarity and legibility of the graphics, deformed traffic route map has been proposed. In this paper, characteristics of deformed traffic route maps are analyzed and the automatic production processes are summarized. To solve conflicts of map symbols in the production process, a method of compression and deforming for traffic route map is come up with based on station displacement, which is driven by force. A displacement model of forced station in traffic route maps is constructed and a displacement algorithm centered on coordinate axis is designed. It shows in the experiment that the conflicts of map symbols can be settled using this algorithm, which establishes the basis for completely automatic production of deformed traffic maps. |
