Research on data mining model of GIS-based urban underground pipeline network

The world-wide deployment of GIS in urban underground pipeline network (UPN) has led to a rapid growth in the amount of information. To improve the management and gather useful knowledge from the UPN´s database more effectively, we integrate the UPN GIS system with data mining technology. In this paper, we study the spatial characteristics of UPN, analyze the basis of data warehouse-based data mining and propose a practical data mining model for UPN. The model performs data integration and data mining and acquires useful knowledge effectively, making the GIS system intelligent and capable of assisting decision-making.
