SUBSEA SERVICESMap seabed and reservoir terrain
Our USV surveys cover marinas, berths, hydro reservoirs and shallow-water infrastructure. Coverage planning and overlapping sonar capture provide the basis for point-cloud review, filtering and surface generation.
ROV NZ / SUBSEA SERVICES
USV seabed surveys & 3D bathymetry
Map underwater terrain with compact surface-vessel surveys, 3D sonar and positioning. Create spatial datasets for planning, modelling and engineering review.
Discuss your projectAgree survey control before mobilisation
Coordinate systems, vertical datums, positioning, coverage and acceptance criteria are defined around the project. RTK positioning supports georeferenced acquisition; achievable accuracy and uncertainty depend on the survey method and control.
Choose practical deliverables
Deliverables can include raw and filtered LAS point clouds, E57 point clouds, GeoTIFF terrain models, DXF contours and OBJ surface meshes. We agree the formats and level of processing with the people who will use the data.
PROJECT EVIDENCE / OKARA MARINA
Mapping the seabed at Okara Marina
The marina survey captured 14.7 million raw sonar observations using overlapping 3D sonar scans and dual-antenna RTK GNSS. Delivered outputs included point clouds, a bathymetric terrain model, 20 cm contours and a surface mesh.
These results describe this survey. Coverage, accuracy and deliverables are defined for each project.
