摘要
广西防汛三维电子沙盘系统利用现代高新信息技术,模拟建设了广西全区及重点河段的三维空间场景,展示流域地形地貌、防洪工程、山洪灾害易发区分布等防汛信息;并在三维场景中实现洪水淹没快速评估、山洪灾害快速定位、山洪灾害影响分析等内容,为广西各级防汛部门的防洪减灾决策提供技术支持。
Base on the cutting edge technology, a 3-D electronic sand table model of Guangxi Province was built for flood control simulation. The geographical features, flood control projects, mountain flood prone areas and other flood-disaster related information were shown in the 3-D model. The proposed 3-D model can be used to demonstrate rapid flood inundation, flash flood risk analysis and impact evaluation, etc. The model provides technical support to the decision-maker at all levels of flood control department in Guangxi Province.
