[Abstract]:Because the current drainage network topology model neglects the detailed characteristics of the drainage network, the topological relationship is too simple to complete the spatial analysis of the specific drainage business model, which hinders the development of the drainage GIS system to some extent. Based on graph theory, a detailed topological model of urban drainage GIS system is proposed in this paper. Firstly, based on the object-oriented method, a topological conceptual model and a logical model are proposed, and the detailed rules for describing the topological relations are added to realize the real simulation of the objective world. Then, in the design of data structure, cross-link list is used as storage structure, which is improved and associated with R-tree to generate spatial index. In spatial analysis, this paper presents a typical spatial query and path analysis algorithm based on R-index and cross-linked list. Finally, taking the development of urban drainage network geographic information system in Zhenjiang as an example, the topology model is developed and practiced. The experimental results show that the topology model proposed in this paper can simulate the objective world more realistically, provide more spatial analysis, complete fast access to massive data, and provide a solution for efficient spatial analysis of massive data in urban drainage GIS system.
