面向规则聚合的地图制图模板设计与实现

The Design and Implementation of Mapping Template for Mapping Rules Aggregation

在分析现有制图模板特点与不足的基础上,以地理空间数据符号化过程为研究对象,将符号化过程分解成不同类型的制图规则,设计了贯穿于符号化各环节的制图模板结构;通过记录用户的制图操作,将符号化各环节的制图规则聚合成不同功能的规则集,实现了制图模板的具体构建。制图模板能够从规则、规则集和模板3个层次引导和约束用户的制图行为,有助于降低制图门槛,减轻用户工作负担。

Based on analyzing the characteristics and deficiencies of the existing cartographic template and according to the whole process of geospatial data symbolization, the symbolization process is divided into different kinds of mapping rules, which helping to design the structure of mapping templates throughout all aspects of symbolization. Through recording the user＇s mapping operations, this dissertation composed the mapping rules of all aspects of symbolization into rule set with different functions and constructs mapping templates. Mapping template can guide and constraint the mapping behavior of the users from the three levels of rules, rule sets and templates, which helps to lower the difficulty of drawing and reduce the users＇workload.
