Transmission lines need to be regularly inspected, typically annually, according to the local in-country regulations. With the rapid development of civil construction and the increasing demand for electricity in recent years, the market segment of power grid construction has grown significantly. Meanwhile, how to efficiently manage such large-scale power line networks and how to guarantee the reliability of power transmission is becoming increasingly important. The power line management is extremely important as branches and brush encroaching on power lines might cause damages such as short circuits or even fire.

LiDAR technology for Powerline corridor mapping is widely accepted as compared to the conventional techniques. LiDAR technology has proved to be highly accurate and reliable in mapping corridors in complex terrains. We have carried out thousands of linear kilometers of Lidar Transmission line classification over the past few years.
