Earthquake Disaster Scene Simulation System for Buildings Based on 3DGIS Technology

According to the features and demands of earthquake rescue on-site, automatic modelling and scene generation methods based on fundamental geographic data were investigated, and an earthquake scene model was proposed considering both effect of local site conditions on ground motion and vulnerability of different buildings. Based on ArcGIS Engine, the system in which the scene of pre-earthquake and post-earthquake can be created automatically and demonstrated intuitively was built with auxiliary functions such as analysis on global seismic damage, prediction of major search and rescue areas and query for key objects. Using fundamental geographic data of earthquake area and basic parameters of earthquake as input data, the developed system can estimate and analyze the seismic damage of buildings and its spatial distribution in earthquake region rapidly as soon as getting basic earthquake parameters, and forecast major search and rescue areas subsequently. The proposed system is suitable to use in earthquake search and rescue, which provides efficient support for earthquake emergency commanding.
