Surveying utility networks at scale

Capture better data. Make better decisions.

Effective asset management and engineering design demand absolute spatial certainty. NM Group combines manned aerial platforms, high-density LiDAR, and advanced photogrammetric processing to capture millions of exact data points across vast transmission and distribution corridors. By delivering a flawless digital replica of your physical infrastructure, vegetation, and surrounding terrain, we eliminate field guesswork and accelerate wide-scale network planning.

FAQs

Survey-grade LiDAR provides the essential geometric foundation for thermal rating analysis, clearance assessments, PLS-CADD engineering design, vegetation management, and the creation of comprehensive digital twins.

Photogrammetry utilises highly overlapping, high-resolution aerial imagery to generate measurable 3D models, detailed orthophotography, and high-fidelity mapping products that provide critical visual context to the structural point cloud data.

Outputs are tailored to your operational needs and typically include classified LiDAR point clouds, digital terrain models (DTMs), digital surface models (DSMs), orthophotography, oblique corridor imagery, and fully attributed, engineering-ready datasets.

Yes. We deploy highly customised aerial survey programmes designed to map everything from dense, localised distribution grids to cross-country, wide-area transmission lines and rail infrastructure.
