Accuracy we work to
| Survey | Horizontal | Vertical |
|---|---|---|
| DGPS control survey | ± 10 mm + 1 ppm | ± 15 mm + 1 ppm |
| Total station survey | ± 5 mm + 2 ppm | ± 3 mm per setup |
| Drone photogrammetry (with GCPs) | ± 2–5 cm | ± 3–8 cm |
| Bathymetric survey | ± 0.5 m position | ± 0.1 m depth |
| Auto level survey | — | ± 1 mm per km (double run) |
| Contour survey (0.5 m interval) | ± 10 cm | ± 5 cm |
Typical values under good conditions. The accuracy for your project is stated in the quotation and confirmed in the report.
Processing and drafting
How we check our data
- Annual calibration of total stations and GNSS receivers at authorised service centres, with certificates
- Bar check of echo sounders before every bathymetric session
- Closed traverses and TBM loops with closure checks
- Independent check points for drone and LiDAR surveys, compared in the report
- Drawing review against the client specification before delivery
