Airborne Laser Scanning aerial survey technology is applied to landform and topographic survey operations on the ground with laser beam technology. It can replace traditional manual surveys that only work on the ground. For large-scale landform and topographic measurements. It can not only save manpower, but also can carry out precise measurement operations for areas that are difficult for personnel to reach and more dangerous. The relevant measurement result data can be provided to engineering or land surveying and mapping units for subsequent design planning and data construction. Significantly improve the efficiency and accuracy of related operations. Take the UHV overhead transmission line planned by TPC as an example. After the preliminary site survey and line planning, the preliminary route selection has been roughly completed. Since the construction or expansion of the overhead transmission line is tens of kilometers long, the mountains along the way may be steep or high altitude. In mountainous areas, there are no existing roads to reach, and the operation is difficult. In the past, manual survey operations were used for overhead lines, which not only affected the progress of the project, but also increased the risk of personnel operating in mountainous areas. If aerial survey technology can be used for processing, it will greatly speed up the progress of the project.This aerial survey technology research is analyzed with the latest survey equipment LiDAR (Light Detection And Ranging) airborne laser scanner, and it is hoped that it will be helpful to the engineering design that needs to measure special terrain.
