3D Nickel Mine Mapping Initiative

5cm-resolution drone imagery transformed into engineering-grade 3D mine models for operational monitoring and volumetric analysis. A global mining technology provider needed a scalable way to convert high-resolution drone captures from nickel mining operations in New Caledonia into accurate 3D terrain models and stockpile measurements. The project supported ongoing operational oversight across multiple mine sites where precision, safety, and engineering compatibility were critical. 5cm GSD terrain accuracy delivered across complex mining environments. Multi-year 3D mapping and stockpile analysis maintained over a five-year engagement. Engineering-ready vector outputs integrated directly into existing mine planning systems.

"High-resolution drone mapping enabled accurate 3D mine modelling, improved stockpile analytics and accelerated safer, scalable mining operations and planning. "

Industry: Energy & Utilities

5cm GSD: High-resolution terrain mapping
5 years: Continuous operational delivery
3D volumetrics: Engineering-grade stockpile analytics

Challenge

The client needed highly accurate Digital Surface Models and Digital Terrain Models generated from dense drone imagery captured across rugged mining terrain. Stockpile measurements had to meet strict volumetric accuracy standards for operational and financial reporting, while all outputs needed seamless compatibility with existing engineering systems and DGN-based mine planning workflows. Traditional surveying methods were slower, riskier, and difficult to scale across remote mining zones.

Approach

SBL Infotech deployed a specialist photogrammetry and geospatial delivery team using Pix4D, Summit Evolution, DTMaster, and MicroStation workflows to process aerial triangulation, orthomosaics, and 3D terrain datasets. The team executed precision feature extraction, vegetation filtering, and DTM refinement to produce clean engineering-grade spatial outputs. Continuous QA and Ground Control Point validation ensured consistent 5cm GSD accuracy across all deliverables throughout the engagement.

Outcome

The client gained a scalable 3D monitoring pipeline capable of supporting safer mine operations, faster terrain analysis, and precise stockpile inventory management across multiple locations. What was previously dependent on labor-intensive field surveying became a high-fidelity digital operating layer for mine planning, reporting, and long-term infrastructure expansion.

UK renewable energy initiative

Smart Solar Potential Analysis

90% reduction in field-survey costs through remote rooftop analysis across London suburbs. A UK clean-energy initiative needed to identify residential rooftops suitable for solar installation at city scale. Traditional field surveys were too slow, expensive, and operationally impractical for the speed required to support national renewable-energy targets. The challenge was to accurately assess roof orientation, sunlight exposure, and shading conditions across thousands of homes — without sending teams on-site. 90% reduction in surveying overhead. High-speed rooftop qualification across London districts. Accurate south-facing and shade-free roof identification for rapid solar deployment.

"Remote rooftop analysis reduced solar survey costs, accelerated renewable-energy planning and enabled scalable residential solar feasibility assessment across urban districts. "
