Study on Simulation Technology of Earthquake Disaster Scene
Based on the technology such as remote sensing(RS), geographic information system(GIS), 3D simulation, and damage prediction, the simulation technology of earthquake disaster scene (STEDS) is the important content of digital disaster reduction and has important research value, which can be used to decision support, virtual training, and popular science education and so on. The general idea of STEDS is introduced in this paper and the key technologies to simulate an earthquake disaster scene livingly are analyzed. Taking a real city for example, the disaster scene of building blocks is completed, which take different colors as the signs of different damage levels under earthquake effect. The 3D building model bases are established by 3D modeling technology, which include 3D intact building models and the damage ones with different damage levels. Based on the replacement rules of models, the preliminary disaster scene of 3D damage building models is realized.
