Drone (UAV) Surveying & Aerial Mapping
Fast, safe, and highly detailed aerial capture for topo, volumes, construction progress, and asset inspection — delivered as orthophotos, contours, and 3D models.
What Is Drone Surveying?
Drone (UAV) surveying uses high-resolution imagery and photogrammetry to generate orthomosaics, point clouds, DSM/DTM, and contours over large areas quickly and safely. With ground control and rigorous QA, we achieve survey-grade outputs suitable for civil, construction, mining, and environmental applications.
It reduces time on site, reaches hazardous or inaccessible areas, and provides rich visual context for design and decision-making.
When / Why You Need It
- ✓Topographic & feature surveys over large areas
- ✓Earthworks volumes & stockpile calculations
- ✓Construction progress & site logistics planning
- ✓Roads, subdivisions, corridors & utilities
- ✓Environmental monitoring & vegetation mapping
- ✓Roof, façade, and asset inspections
Our Process
Confirm outputs, accuracy, airspace permissions, and safety plan. CASA-compliant operations.
Establish survey control (GDA2020/MGA) and GCP/CP layout to meet tolerance requirements.
Plan flight lines, forward/side overlap, and altitude for required GSD; capture nadir & oblique imagery if needed.
Photogrammetry to produce orthomosaic, point cloud, DSM/DTM; noise filtering and colour balancing.
Report RMSE against check points; verify vertical/horizontal accuracy and coverage.
Export CAD/BIM-ready outputs; provide viewer files and a short walkthrough.
Outputs You’ll Receive
- ✓Orthomosaic (GeoTIFF/ECW), tiles, and web-ready imagery
- ✓Point cloud: .LAS / .LAZ / .E57
- ✓DSM/DTM and contours (DWG/DXF)
- ✓Surface models for volumes and cut/fill
- ✓QA summary with control residuals (RMSE)
Accuracy, Time & Cost
With robust control, sub-decimetre horizontal accuracy is typical for civil works. Capture often completes within 1–3 hours per site; processing depends on area and deliverables. Pricing scales with area, access, permissions, and required tolerances.

Frequently Asked Questions
- Is drone surveying legal on my site?
- We operate within CASA rules, obtain required approvals, and follow site inductions and safety plans.
- Do you use ground control?
- Yes — we set GCPs/CPs on GDA2020/MGA to achieve reliable absolute accuracy, verified in the QA report.
- Can you integrate with our CAD/BIM workflow?
- Absolutely. We provide DWG/DXF contours, surfaces, and point clouds compatible with Civil 3D, 12d, Revit, and Navisworks.
- What about restricted airspace or urban areas?
- We assess airspace, obtain permissions where possible, and adapt capture methods to meet compliance and safety.
- How do you manage privacy?
- We limit capture to agreed extents and can blur/mask imagery if requested. Data is secured and shared privately.
What Clients Say
“The aerial survey gave us contours and volumes in days, not weeks — huge boost to planning and progress claims.”
