Drone surveying
& mapping.
Survey-grade aerial data capture for topographic, volumetric and orthophoto surveys. GNSS-controlled accuracy, ready for CAD, GIS and BIM workflows.
What we
deliver.
Drone-based surveying delivers the speed and access of aerial capture with the precision of traditional survey methods. Where ground teams would need weeks of access, road closures and risk assessments, a drone captures the same data in hours — at densities that no walking surveyor can match.
We deliver to defensible accuracy. Every project is planned around the deliverable: a 1 cm GSD orthomosaic for stockpile volumes is a different mission to a 5 cm topographic survey of a brownfield site, and both are different again to a referenced point cloud for as-built BIM verification.
Capability
- Topographic surveys with contour generation and DTM/DSM models
- Volumetric surveys for stockpiles, excavations and earthworks
- Orthomosaic photo-maps with sub-cm GSD where required
- Linear corridor capture for highways, rail and pipelines
- PPK / RTK workflows with permanent base station or fixed GCPs
- Deliverables tailored to CAD, GIS and BIM stacks
