3D Site Mapping & Volumetric Analysis

Drones have transformed the way mines survey their sites. Instead of teams walking the benches and climbing stockpiles, a single drone flight can collect hundreds of overlapping photos, which software converts into precise 2D Ortho mosaics and 3D models. These models provide centimetre‑level detail on terrain and elevation, making it easy to monitor benches, waste rock piles, 3and stockpiles. Because the aircraft flies autonomously along pre‑planned flight lines, operators can safely stay in a vehicle or control room while the drone does the work. This approach drastically reduces exposure to hazards and speeds up surveying. Our aircraft can cover large areas quickly and generate repeatable, accurate outputs principles that apply equally to mining sites.

We use the Matrice 4Thermal platforms for mapping and volumetric surveys. Its mechanical shutter and RTK module ensure every photo is precisely geo‑tagged, producing maps that align perfectly with your mine’s coordinate system. The drone folds for transport yet can survey up to 200 hectares per flight—more than enough for most open‑pit operations. Its 48MP wide camera and high‑zoom telephoto lens capture high‑resolution images from safe stand‑off distances, and its RTK enables centimetre‑level accuracy. The drone uses overlapping flight patterns that produce dense point clouds; when processed, these yield elevation models and volumetric reports and is also equipped with a thermal sensor that reveals hidden issues.

What you receive

• High‑resolution 2D Ortho mosaics: Seamless, distortion‑free maps of the entire site that engineers can measure from and import into CAD or GIS.

• 3D terrain models & point clouds: Detailed digital surface models showing benches, haul roads, stockpiles, and infrastructure—ideal for design work, cut‑and‑fill calculations, and surface change monitoring.

• Stockpile volume calculations: Accurate volume reports for individual stockpiles using base‑plane methods. Aerial surveys eliminate the need to climb piles and reduce the risk of slips and falls.

• Change‑detection & compliance documentation: By comparing surveys over time, you can track material movement, confirm extraction progress, and meet reporting requirements.

Why this matters

By replacing labour‑intensive ground surveys with drone mapping, mines reduce risk, save time, and improve accuracy. Flights can be scheduled as often as needed, weekly, monthly or after major blasts, creating an up‑to‑date digital twin of the mine. The georeferenced outputs integrate seamlessly with mine‑planning software, supporting better decisions on excavation, stockpile management, and reclamation. Simply put, drone mapping delivers precise data faster, so your team can spend more time analysing and less time measuring.
