Over 200,000 miles of high-voltage power transmission lines crisscross the United States, while over 5.5 million miles of local distribution power lines connect power plants to homes and businesses. Federal and State vegetation management regulation mandates vegetation clearance areas around high-voltage transmission lines, and Utility companies rely on cyclical power line vegetation management maintenance schedules. Yet the increase in catastrophic wildfires leads these Utility companies to expand clearance areas to include roadside vegetation management and canopy fall-in, as well as even larger fire hazard zones in remote areas which can trip power lines and affect service. Utility companies are increasingly adopting utility vegetation management imagery, LIDAR, IoT sensor data, and myriad other data sources, to identify vegetation and other potential hazards to transmission lines. Yet the scale of these data sources, which can include millions of trees over thousands of miles, is far beyond the capability of their existing vegetation management software analytical capabilities.
