Problem

Hetch Hetchy needed to manage trees near power lines while preserving protected forests. Inspections required manual distance calculations.

Approach

The utility adopted LiveEO's Treeline service, built on AWS, to analyze satellite imagery with AI. Its crews used predicted vegetation risks to prioritize pruning, while the forester assessed tree health.
