Data Modeling and Visualization of Guangzhou Underground Space.

The exploitation of Guangzhou underground space is very rapid and it needs an information platform to manage the data. Because of the complexity of underground space data, there is no mature system to manage, visualize and analyze all these data: pipeline, underground building and geologic data. Based on the construction practice of integrated management information platform for Guangzhou underground space, this paper illustrates the key technologies of underground space management information system which include data structure, data modeling, database integration, visualization, comprehensive analyze and shared use.
