Environmental factors are responsible for most of the over-head lines issues, and a significant part of them is related with vegetation, mostly on dis-tribution grids. Maintenance is the key to reduce the occurrence of vegetation related events, but it has a significant impact on the cost of power line asset management and thus must be optimized. This work proposes a method to cal-culate vegetation approximation rates, based on LiDAR acquired during air-borne inspections, in order to optimize maintenance processes and reduce the impact of this activity on the local biodiversity.
