What is a drone survey?
A drone survey uses an unmanned aircraft fitted with a camera or LiDAR scanner to capture the ground below it. The captured images are stitched together using photogrammetry software to create accurate maps, 3D models and volume measurements.
Photogrammetry vs LiDAR
Photogrammetry uses overlapping photos to reconstruct terrain in 3D. It is cost-effective and excellent for visible features. LiDAR fires laser pulses to measure distance, and it cuts through vegetation to reach the ground — ideal for forested or vegetated sites. For most site surveys, photogrammetry at 3–5 cm/px is more than enough; LiDAR becomes valuable for dense vegetation or very high accuracy requirements.
How drone surveys save money
A 50-acre plot that takes a land surveyor several days and a full team can be mapped by two people in under two hours. Site managers get stockpile volume calculations in the same afternoon, real-time progress tracking, and a permanent record for dispute resolution. The return on investment is immediate and large.
What you should expect from a survey pilot
- A clear plan for ground control points (GCPs) if you need survey-grade accuracy
- GPS/RTK-equipped drone for consistent positioning
- Deliverables in an agreed format: GeoTIFF, orthomosaic, LAS point cloud, or a DWG/Revit-compatible model
- A written accuracy statement — e.g. “horizontal accuracy within 5 cm”
