摘要
随着信息技术的快速发展,电子沙盘展示系统在军事、城市规划、灾害防治等领域得到广泛应用。文章基于Cesium平台设计并实现了一套电子沙盘展示系统,重点研究其在地理信息可视化与空间分析方面的应用。系统充分利用Cesium的三维渲染能力,实现了地形地貌展示、三维模型加载、空间分析等核心功能,并通过数据处理技术提升了地形与模型数据的整合效率。创新性地在三维地图中叠加地质灾害点VR全景数据,实现了信息的多元化展示。此外,系统集成了图层控制、空间查询、距离测量等实用功能,显著提升了用户体验。测试结果表明,系统运行流畅、功能稳定,能够满足地理信息展示与分析的需求,具有较高的实用价值和推广意义。
With the rapid development of information technology,electronic sand table display system has been widely used in military,urban planning,disaster prevention and other fields.Based on the Cesium platform,this paper designs and implements an electronic sand table display system,focusing on its application in geographic information visualization and spatial analysis.The system makes full use of the 3D rendering ability of Cesium to realize the core functions of terrain display,3D model loading and spatial analysis,and improves the integration efficiency of terrain and model data through data processing technology.The VR panoramic data of geological disaster points are innovatively superimposed on the 3D map to realize the diversified display of information.In addition,the system integrates practical functions such as layer control,spatial query,and distance measurement,which significantly improves the user experience.The test results show that the system runs smoothly and has stable functions,which can meet the needs of geographic information display and analysis,and has high practical value and promotion significance.
