| 摘 要： | 灾情信息的可视化表达是地理信息系统应用于辅助应急救灾工作的一个重要方面。本文将二三维GIS各自的优点整合到一个完整的可视化系统中,并通过一定的联动机制使2者的数据显示与操作同步,着重介绍了二三维联动技术的原理、实现方法等问题,设计了基于二三维混合结构的GIS,同时包含二、三维GIS环境并支持二三维联动模式下的灾情可视化和相关分析工作,最后以巨灾综合信息集成显示系统为例,并给出了二三维联动实现的基本设计方案。

| Abstract: | Visualization of disaster information is an important aspect when Geographic Information System(GIS) used in supporting the emergency relief work.The paper explained that how to combine the respective merits of the 2D&3D GIS into a complete visualization system,and synchronize the data and operations through the specific interactive mechanism.And it focused on the principle of 2D&3D interactive technology,implementation method and other issues,and designed the GIS based on 2D&3D hybrid structure with 2D&3D GIS environment supporting for disaster visualization and analysis in 2D&3D interactive mode.Finally,it took the Disaster Information General Integrated Display System as an example,and gave the basic design program to achieve 2D&3D interactive function. |
