摘要
运用GIS技术建立城市地下管网网络模型,是城市地下管网管理信息系统实现空间分析功能的必要条件.本文以城市上水管网为例,探讨了在CIS范畴中建立网络模型的基本思路与实现方法.
In order to realize the spatial analysis function of the urban underground pipeline-network information system it is necessary to establish the network model of urban underground pipeline-network by means of GIS technology. In this paper the urban water-supply line network is taken as an example to discuss the basic train of thoughts and the realizing method of establishing the network model within the GIS category.
