浙江省电子沙盘气象应用系统

Zhejiang Electronic Sand Table System for Meteorological Applications

用高程数据建立电子沙盘表面模型,并对高程数据、矢量数据和影像数据进行三维可视化处理,在三维场景中建立了渲染过的浙江省电子沙盘模型;以Microsoft.NET为开发平台,基于ArcGIS Engine构建了浙江省电子沙盘显示平台,实现电子沙盘的集成显示、基本地图操作、自动站叠加显示、属性查询、MICAPS第4类网格资料分析功能,为用户提供了一个直观形象的三维环境,便于结合地形进行各种气象分析。

The electronic sand table model is established by means of elevation data,and elevation data,vector data,and image data are visualized in three dimensions.A rendered electronic sand table model for Zhejiang Province is established in the three-dimensional scene.The Zhejiang electronic sand table display platform is constructed based on Microsoft.NET and ArcGIS Engine.It completed several functions such as the integrated display of electronic sand table,the basic operation of maps,attribute information query,automatic overlay display,and the analysis of MICAPS grid data（the fourth category）.It provides a manifest three-dimensional environment for users to analyze conveniently a variety of meteorological elements in combination with terrain.
