本文以长江下游南京以下河段为例介绍了一种基于GIS技术的水下地形可视化计算新方法,对冲淤变化进行高效、准确的定量计算,对河道形态及长江下游河段冲淤部位等空间分布进行实时的可视化显示。
In this paper, a new method of visualization of underwater terrain based on GIS technology is introduced in this paper. The calculation of erosion and siltation is carried out with high efficiency and accuracy. The channel morphology and the space of erosion and silting sites in the lower reach of the Yangtze River Distribution for real-time visual display.
