【摘要】 根据洪水演进模拟对于可视化的需求,以AutoCAD Map 3D 2011为基础平台,利用Active X/VBA接口编程技术,进行二次开发建立洪水演进可视化系统。采用CAD图元与GIS数据结合显示的方法,在Map 3D中实现了洪水演进的可视化,并针对工程实际需求,在系统中研发实现了淹没区域的点查询、面查询及缓冲区分析等实用功能。更多还原

【Abstract】 Based on the demand for visualization of flood propagation simulation,the secondary development of AutoCAD Map 3D 2011 has been done by using Active X/VBA interface programming technique.Visualization system of flood propagation has been realized by means of CAD primitives combined with GIS data display method.According to actual engineering requirement,the point query,surface query,buffer area analysis and other useful features are developed in this system.更多还原
