Visual Management and Analysis on Drainage Networks in Kunming Based on GIS

With the rapid urbanization of Kunming City, the water environment of the City is becoming worse. Informationalized and scientific drainage network management is essential to improve urban water environment. To solve the current problems of Kunming drainage network, we developed an integrated urban drainage network information platform. Architecture design, functional design and spatial database, as well as some key technologies of this platform, for example, Web GIS, ArcObjects, are illustrated. This platform has already been applied to the drainage network management of Kunming, and it has realized the visual management of geospatial information, network analysis, drainage data real-time monitoring and Web publication of information. All of them provide comprehensive and accurate information support and scientific decision-making on urban drainage for the operation and management departments.
