不同工程阶段的水库库区地形测量方法研究

Study on Topographic Survey Method of Reservoir Area in Different Engineering Stages

随着测绘科学技术的进步,水利工程测量方法可选择性更多,文章根据水库不同环境条件、不同的工程阶段,通过采用GNSS定位、测深仪和无人机测量技术获取测量数据,利用Pix4Dmapper、ARCGIS等数据处理软件建立了库区数字高程模型(DEM),为水库扩库增容工作提供可靠的基础数据。

With the progress of science and technology of surveying and mapping,engineering measurement method has more options.According to the different environmental conditions and engineering stage of reservoirs,this paper puts forward a digital elevation model(DEM),through the adoption of GNSS positioning,sounder and drones for measuring data,using Pix4Dmapper,ARCGIS and other data processing software.It helps provide the reliable data basis for reservoir capacity expansion works.
