Bathymetric Survey UAE | Hydrographic Survey Services
Professional bathymetric survey services providing accurate underwater mapping, depth measurements, and seabed data for marine construction, ports, dredging, and infrastructure projects across the UAE.
A bathymetric survey measures the depth and shape of a waterbody’s floor, mapping underwater features to produce accurate charts for navigation, dredging, and marine construction planning. It is an essential first step for projects involving ports, channels, marinas, pipelines, and coastal infrastructure.
Our bathymetric surveys are carried out using a survey vessel equipped with an echosounder and transducer, which transmit sound waves to the seabed and measure the return time of the echo to determine water depth. This data is integrated with GNSS positioning to accurately map every measurement.
For shallow water, restricted access areas, or projects requiring rapid data collection, we also provide drone-based bathymetric LiDAR surveys. This method efficiently captures seabed and shoreline data, offering a practical and cost-effective alternative to conventional vessel-based surveys.
Our bathymetric survey services support:
- Port and harbour development
- Dredging and channel maintenance
- Marina and coastal construction
- Pipeline and cable route surveys
- Navigational chart production
- Obstruction and hazard detection
Survey data is processed into project-ready deliverables, including bathymetric charts, digital terrain models (DTMs), depth contour maps, and GIS-compatible datasets. These deliverables provide engineers, marine consultants, and contractors with accurate seabed information for planning, design, dredging operations, navigation, and marine infrastructure development.

Bathymetric Survey FAQ
It’s used to map the depth and features of a waterbody’s floor, supporting dredging, port development, navigation safety, and marine construction planning.
Data is typically collected using an echosounder mounted on a survey vessel, linked to GNSS positioning for accurate location, or using drone-based LiDAR for faster aerial coverage in shallow or restricted areas.
Drone surveys are useful in shallow water, hard-to-access areas, or where a fast turnaround is needed, offering a quicker and often more cost-effective alternative to vessel-based surveys.
Deliverables typically include bathymetric charts, depth contour maps, digital terrain models, and GIS-compatible datasets for use in engineering and planning software.
Yes, accurate seabed depth data is essential for engineering design, dredging planning, navigation safety, and regulatory approval before marine construction begins.
With GNSS-linked echosounder or LiDAR systems, depth measurements are typically accurate to within a few centimeters, meeting the precision required for dredging and engineering design
