摘要
本文提出了一种基于规则库的目视航图自动化制图技术,详细阐述了基于规则的要素自动综合取舍、自动符号化、注记自动配置的实现方法。基于GIS COM组件开发了一个目视航图制图原型系统,通过对规则库中各种规则的配置、管理和调用,可方便快捷地制作出目视航图产品。
An automatic cartography method for VFR aeronautical charts based on rule database was introduced in this paper, and three key technologies based on rules were illustrated, including the automatization of cartographic generalization, feature symbolization and annotation placement. Based on GIS Components, a prototype system of making VFR charts was developed, which could be used to make VFR aeronautical charts conveniently and quickly with the help of various pre-configured rules in rule database.
