摘要
本文论述在基于ArcGIS 9的地下燃气管网地理信息系统中管网模型的建立方法,并使用ArcGIS的扩展类技术,通过对网络连通关系和父子关系的控制,模仿数据库触发器,实现在GeoDatabase数据库层面上应用管网规则,保证多用户数据编辑时管网数据的一致性和完整性。
The method of building gas pipeline was discussed in this paper using ArcGIS. By controlling relationship of connectivity and paternity, simulating trigger of database, the rules of pipeline were realized based on Geodatabase and extension class of ArcGIS. The consistency and integrality of pipeline data were ensured when multi-user edit data.
