Drones - also known as Remotely Piloted Aircraft (RPA) or Unmanned Aerial Vehicles (UAV) - have revolutionised the way geospatial data is captured. In the hands of a skilled and certified operator, they offer a rapid, cost-effective means of collecting high-quality spatial data across a range of applications.
We use drone technology to deliver:
Orthomosaics – High-resolution, georeferenced 2D imagery that provides a clear, accurate visual record of your site
Digital Elevation Models (DEMs) – 3D terrain models that support planning, terrain analysis, and surface modelling
Volumetric Assessments – Precise calculations of stockpile volumes, cut/fill quantities, and excavation progress
4D Differential Models – Repeat surveys over time to detect changes, track material movement, monitor excavation, and identify potential hazards
These tools enhance decision-making across exploration, operations, and rehabilitation - helping to visualise change, reduce uncertainty, and stay aligned with project goals.
Drone imagery can be transformed into detailed 3D terrain models using photogrammetry - a process that triangulates overlapping images to reconstruct surface geometry.
Modern drone data acquisition offers a range of benefits:
Accurate, high-resolution data that’s current, cost-effective, and tailored to your project
Safe and flexible survey methods, ideal for remote or complex terrain
Repeatable workflows that enable differential or 4D mapping to track changes over time
Expert data processing and analysis to support decision-making

Harness the power of geospatial data in your ongoing operations and mine planning;
Safe, flexible and cost-efficient data gathering
Rapid terrain mapping to support pit design, haul road planning and stockpile managment
Monitoring to track progress, detect change and adjust operations
Accurate GIS-based calculation of material volumes (overburden, ore, tailings) to support production tracking and compliance
Baseline documentation for rehabilitation planning and regulator submussions
Progress reporting and assurance for regulators, community stakeholders and shareholders
Photogrammetric survey of the Abbotsford Convent, Melbourne. Drone surveys are fast, affordable, and precisely repeatable. The resulting 3D models let you explore your site from your desktop — measuring geometry, height, length, area, and volume with confidence and build your dataset
Talk to us about how drone-based data acquisition can help inform applications, planning and decision making:
High resolution terrain mapping to generate detail topographic maps of prospective areas
Creation of orthomosaics - high-resolution, geometrically corrected aerial images from overlapping photos
Visual documentation of your site to support permit applications, work plan submissions and stakeholder engagement
Aerial imagery and mapped overlays can be submitted to regulators, to improve transparency and facilitate approvals
Evaluate site conditions, access, operationing areas, potential targets, to inform applications or work plans
