摘要
论述了基于特征的GIS概念,在分析传统的专题图层方法的不足后,提出了基于特征的市政道路GIS系统的图形信息设计方法,按照该方法的要求对CAD图形中的道路进行动态分段,获取路段信息,在此基础上灵活组合构成地下管线、道路、街坊等不同的语义特征。
The concept of feature-based GIS is provided. The shortage of the method of subject layers is discussed and a feature-based GIS application for municipal road management is designed. A line in CAD file is divided to many segments automatically to construct the shapes information of road segments. Compared to the method of subject layer, many features such as underground pipelines, roads, blocks, etc. can be gotten by the segments easily without collection again in CAD file.
