| 摘 要： | 针对在给水管网管理信息系统建设中水力模型和地理信息系统的结合问题,提出了基于GIS的利用数据挖掘和数据检查技术建立中间层,并以之作为水力模型数据来源的方法,从而避免了水力模型会继承GIS中的数据缺陷和数据错误等不足,同时实现了GIS与模型的无缝连接和同步更新。实际应用情况表明,通过中间层来建立和维护水力模型简单、可靠、高效;与传统方法相比,模型更新及时、维护费用低,且适用于多种GIS平台,通用性好。

| Abstract: | Aimed at the combination of hydraulic model with geographic information system(GIS) in the construction of management information system for the water supply network,a method of using data mining and data checking technology based on GIS to create "a middle layer" serving as the data source of the hydraulic model was put forward.The middle-layer technology can prevent the hydraulic model from inheriting possible data incompleteness and error in the GIS,realize the seamless integration between GIS and the hydraulic model,and synchronously update.The practical application proves that the hydraulic model constructed and maintained by the middle-layer technology is simple, reliable and efficient.Compared with conventional technologies,the hydraulic model can be updated in time,is lower in maintenance cost,acceptable for more types of GIS platforms and universal in use. |
