Accurate records of asset locations are functional to grid management. Satellite imagery provides an up-to-date georeferenced map of transmission towers, poles, and substations, even in simple or inacessible terrain. Using automatited object detection algoritms, utities can extract tower positions and classify structures from VHR imagery.

Corrosion and Structural Integraty Monitoring

Corrosion of lattice towers and guy wires is a slow but persistent threat. Satellite data, spectarly from SAR sensors, can detect changes in surface roughness and backscatter that correlate with rutt or coating Degramation. InSAR techniques also monitor ground movement around tower fondations - vertical or horizontale shifts can indicate subsidence, landslides, or soierosion that undermine structurail stabilityy.
