基于ArcGIS Server的水动力流速场网络可视化

Web Visualization of Hydrodynamic Force Velocity Field Based on ArcGIS Server

传统的流速场网络可视化通常将流速场数据转化为GIS支持的图层,其缺点是前处理工作量很大,且可视化效果并不理想。在Arc GIS Server平台上,扩展了Arc Objects组件,定义了流速场Web服务组件,实现了流速场数据的网络可视化,并应用于山东东平湖蓄滞洪区风险图展示系统。结果表明,该方法能将流速场信息直接发布到网络浏览器中,既提高了流速场的可视化效率又增强了可视化效果。

The traditional way to show velocity field is to transform the data into standard GIS layer. The drawbacks of this way are that it has masses preprocess work to do and the visualization effect is not so good. Based on the platform of Arc GIS Server, this paper expanded the several components in Arc Objects, defined the Web components of the velocity field, and realized the velocity field data Web visualization. The system was applied to show the velocity field of Dongpinghu flood storage area. The results show that this method can release the velocity field information directly to the Web browser, and enhance the efficiency of the visualization of the velocity field and promote the visual effect.
