Quality inspection is an important process of producing and quality control of digital chart. Furthermore,reasonable controlling method of chart quality is the essential approach to improving the chart quality. This paper applies the rules and the principle and method of rule base to quality checking of digital chart. The paper initially analyzes the quality characteristic and checking content of chart and introduces the inspecting mode,process and regulation making,finally designs and forms the data structure of rule base of chart quality,defines and analyzes special relations regulation and restricting rules depiction.%将规则和规则库的原理和方法应用到了数字海图质量检测中,首先对数字海图质量规则的表示方法进行了介绍,在此基础上,对基于规则驱动的数字海图质量检测模型、流程和规则的定制进行了介绍,最后设计和构建了海图质量规则库的数据结构,分别对空间关系规则、属性约束规则描述表进行了定义和分析.
