Global Mapper在水利工程中制作DLG的应用探讨

Discussion on the application of Global Mapper in DLG production for water conservancy project

针对无人机和遥感技术产生的数字地理产品DEM、DOM及点云数据转化到数字线划图(DLG)的不方便性,探讨运用Global Mapper转化为常用绘图软件CASS易于识别的数据,从而提高DLG快速绘制的方法。研究证明,Global Mapper软件用于水利工程测量突破了传统利用无人机数据的技术瓶颈,高效的实现4D产品之间的转化利用。

Aiming at the inconvenience of rendering DLG by converting the digital geographic products generated by UAV and remote sensing technology such as DEM,DOM and point cloud,the author discussed the method for improving the fast rendering of DLG by using Global Mapper to convert the digital geographic products into easily recognizable by commonly used mapping software CASS.The results of study demonstrate that Global Mapper software has broken through the technical bottleneck of traditional UAV data utilization in water conservancy engineering measurement,and achieved efficient conversion and utilization of 4D products.
