地震灾害三维可视化系统



   基于数字地球理念下的空间信息高效可视化技术,融合多遥感器、多时相、多分辨率的航空、航天遥感数据,开发了地震灾害三维可视化系统,建立了汶川地震灾区与玉树地震灾区三维数字环境,对地震区重大崩塌、滑坡、泥石流等地质灾害进行了实时分析,为抗震救灾,抢险、排险提供了第一手的灾情形势评估信息。

   Based on the high efficiency spatial information visualization technology under the concept of digital earth, a 3D visualization system of earthquake disasters was developed with the fusion of multi-sensor, multi-temporal, multi-resolution airborne and spaceborne remote sensing data. We have built 3D virtual environments for the earthquake-hit areas of WenChuan and YuShu and conducted real-time analysis of geological disasters (e.g. huge collapses, landslides, and debris-flow etc.) as well as providing first-hand disaster assessment information for rescue and relief work.
