城乡一体化地籍中道路自动综合研究

Automatic generalization of road in urban-rural integrative cadastral information system

本文介绍了分形分析与制图综合的关系,把分形分析理论应用到城市道路自动综合中,利用分形分析理论与方法对城市道路进行自动综合,沿用己有算法针对城市道路的地理特征,改进了城市地图中基于道路几何特征的综合算法。结合分形分析方法进行制图综合,使制图综合中抽象的问题具体化,分形分析方法中自相似性给出了制图对象的局部和整体间在结构特征和形态规律方面的规律性,有效提高制图综合的智能化程度。

The paper discussed the relation between fractal analysis and cartographic generalization, applied the theory of fractal analysis to the automatic generalization of urban roads and ameliorated the algorithm of automatic generalization based on the geometric characters of cartographic urban roads. The fractal analysis method can concretize the abstract problems, because the method can con- struct the proper mathematical models according to the related geographical information. The self-similarity of fractal analysis gives the rules of structure-configuration character of cartographic objects. The fractal analysis method can effectively improve the intellectualization on cartographic generalization.
