This study focuses on evaluating the capability of optical satellite data in monitoring trees with the potential to cause damage. The study focuses on the application of very high-resolution optical satellite data, specifically Pléiades and SkySat imagery, as a viable alternative to airborne LiDAR for monitoring tree fall risks. The comparative analysis of height estimations from optical satellite data against airborne LiDAR data unveils valuable information on adopting efficient strategies for managing vegetation risks, particularly those impacting power transmission systems. The outcomes of our research contribute substantially to ongoing initiatives aimed at developing vegetation management strategies along powerlines, offering valuable information for decision-makers involved in assessing and mitigating risks associated with tree falls
