摘要

采用三维地理信息系统World Wind对汶川地震灾区应急系统建设进行了研究。通过对World Wind中地形影像资料调度模式、实时渲染流程、地名标注和救灾路径添加等方法的研究,显示了地震灾区三维地理状况,为救援进展提供了直观的环境展示。通过对唐家山DEM数据的测算,得出堰塞湖的水位库容曲线和淹没面曲线,在World Wind中对淹没情况进行了模拟显示。研究成果在地震应急救援上得到了一定的应用。
Using 3D geographic information system--World Wind,Wenchuan earthquake area was displayed.The system could provide intuitionistic earthquake area situation,and advise suitable rescue route.In order to realize the disaster rescue emergency system,the following methods were studied:running mode and real-time rendering of DEM and imagery,adding labels and succor route information in World Wind.The reservoir capability curve and submerge area curve of Tangjiashan Earthquake Lake were obtained by calculating the DEM of this area,and the submerged condition were shown in virtual environment.The study result of World Wind is useful to earthquake emergency system and earthquake succor.
