| Abstract: | VR-GIS is a kind of new technology which integrates the characteristics of virtual reality with GIS. Digital flood control system of city based on VR-GIS is playing an important role in decision-making. In light of the 3D-system development of flood control in Harbin, this paper discussed some key problems about digital flood control system developed with VR-GIS, including 3D scene construction, database construction, flood simulation, etc., which provided a research platform for digital flood control system. |
