三维立体可视化震情会商系统平台设计与实现

Design and implementation of 3D stereo visualized system platform for earthquake consultation

随着政府和社会公众对建立现代震情会商系统的需求日益增强,本文尝试应用三维GIS技术和体绘制可视化方法,解决地震会商过程中的多源、海量地学数据的协同可视化问题。设计并实现了三维立体可视化会商系统平台,并在其上将汶川余震分布、数值模拟和华北精细地下三维速度结构等研究成果进行了集成测试。

Earthquake consultation is an important way for our government facing and dealing with earthquake disaster and achieving the earthquake forecast ideas, through consultation of multi-discipline experts. During the process of consultation, the experts must reach a con sensus on the earthquake issue in a short time, based on the massive datum and results. With the increasing demands of government and public on building modern earthquake con- sultation system, we try to apply the 3D GIS technology and volume rendering method, sol ving the collaborative visualized problems of multi-source and massive muhi-geosciences data during the consultation in this paper. We have designed and implemented the 3D stereo visu alized system platform for earthquake consultation, and tested the results of Wenchuan after shock distribution and numerical simulation and the 3D velocity structure of northern China etc on this platform.
