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.
