摘要：Typically, it has been a challenge for utility companies to implement more automated approaches to powerline maintenance. Our study considers using two emerging technologies – LIDAR and direct multiple viewing digital cameras – to address an aspect of this challenge. Airborne-LIDAR and the direct geo-referenced digital cameras are presented as tools for managing vegetation in a utility's Right-Of-Way: to maintain required clearances between powerlines and surrounding vegetation, and to detect change in the vegetation over a given timeframe. Digitizing LIDAR waveforms for powerline management will have an impact on the way powerline companies operate. We highlight here advantages and drawbacks utility firms may face in leveraging this new technology. This new surveying technique will also be assessed with respect to the risk management cycle and the national regulations to ensure it permits utility companies to fulfil the requirements of policies regarding powerline safety. Drawing from the review of a case, this study aims to introduce a workflow that utility firms can follow for their vegetation management programs. The workflow will provide utility companies a cost-effective method to manage their Utility Vegetation Management programs more effectively
