摘　　要：总结了空间多尺度地图符号变换规则,提出了一种多比例尺地图符号自动转换方法。该方法根据地图符号分类和视觉变量,依据符号的几何、语义、特殊效果等联合特征将符号变换转化为几何变换、语义变换、特效变换及其3种形式的组合,将其抽象为变换规则,并从逻辑上构建知识规则库,基于规则建立多尺度地图符号变换模型,实现不同比例尺地图符号变换。以1∶10000和1∶50000两种尺度国家标准地形图符号为例,进行了实验验证,验证了方法的有效性和高效性。In this paper,we summarized the rules for transforming map symbols of multi-scale and proposed an automatic conversion method for multi-scale map symbols.According to map symbol classification and visual variables,the method converted symbol transformation into geometric transformation,semantic transformation,special effects transformation and their combinations,and abstracted the different forms into transformation rules and logically constructed a knowledge rule base.Then,this methodbuilta multi-scale map symbol transformation model based on the rules to realize different scale map symbol transformations.We carried out experimental validation with two scales of 1∶10000 and 1∶50000 national standard topographic map symbols to verify the effectiveness and efficiency of the method.
