摘要
利用地理信息系统(GIS)结合空间三维理论来管理和研究城市地下管线,是一项颇具实用性的计算机应用技术。文章首先对城市地下管线的数据类型进行了分析,并对三维GIS数据结构作了简要介绍。在此基础上,设计出具有较好通用性的地下管线三维矢量数据结构,该数据结构结构简单,冗余度低,适合于地下管线空间建模和空间分析的要求,最后给出了管线数据的编码方式。
Using GIS combined with spatial 3D theory to manage and study urban underground pipelines is one of the computer application technologies that has great practicability.this paper first analyzes the data type of the urban underground pipelines and gives a brief introduction of the data structure of 3D GIS.Then based on which,the 3D vertor data structure of the underground pipelines is designed,which has good applicability.This data structure has a simple structure and low redundancy so that it is very fit for spatial modeling and analyses.A coding method of pipelines data is given at last.
