模板驱动的城市地下管线出图研究

摘要

According to the features of underground pipeline data ,a unified data model is designed based on extended Geodatabase ,which realizes the unified modeling of pipeline data .In order to solve the problem of low mapping automation and intensity work ,a pipeline model is designed according to the national standard ,which mainly contains symbol model ,annotation model and drawing margins model .Taking rectangle division as an example ,it describes the design framework of synthesized pipeline mapping driven by model ,and then analyses the key technologies .Finally the paper takes the underground pipeline data in Luoyang as an example to make an experiment ,which realizes the initial intelligent mapping of urban underground pipeline .%针对城市地下管线数据的特点，设计基于扩展Geodatabase的地下管线统一数据模型，实现管线数据的统一建模。为了解决城市地下管线出图自动化程度低及工作量大的问题，按照国家标准设计适合管线出图的模板，主要包括符号模板、注记模板和图廓整饰模板。以矩形分幅为例，介绍模板驱动下的综合管线出图设计框架，分析其中的关键技术。最后以洛阳市地下管线数据进行实验验证，初步实现城市地下管线出图的智能化。
