基于OpenGL的DEM数据与河流矢量数据集成

The Integration of DEM Data and River Vector Data Based on OpenGL

在现有DEM数据和MIF河流矢量数据,本文应用OpenGL实现DEM数据与河流矢量数据集成,实现河流区域的3维仿真显示,其中数据采用嘉荫县地区的DEM数据及河流矢量数据。经实验表明,在OpenGL平台下,可以实现DEM数据与河流矢量数据的有效结合,为防汛监测提供很好的显示平台。

This paper realized the integration of DEM data and river vector data based on OpenGL using the existed DEM data and river vector data in MIF format,realized the 3D simulation visualization of river area of Jiayin county.The experiment showed that it is feasible to realize the effective combination of DEM data and river vector data based on OpenGL platform which provides visualization platform for flood control monitoring.
