Advanced Survey Technologies Deliver Clear View of Geologic Hazards

Electric utilities commonly use trained foresters, traversing thousands of miles, to manually identify vegetation or other geographic hazards posing risks to transmission infrastructure. For one utility in the Western United States, the challenging terrain and accuracy limitations of laser range finders used to visually identify at-risk trees resulted in 1,424 trees assessed as requiring maintenance, potentially costing $200,000.

Months later, surveying the same assets using high-resolution LiDAR (Light Detection and Ranging) on fixed wing...
