Bathymetric Surveys FAQ

There are some differences between bathymetric and hydrographic surveys:

  • Bathymetric surveys are a specific type of hydrographic survey that focuses on mapping the underwater terrain, providing detailed information on water depths and the land beneath the surface.
  • Hydrographic surveys encompass a broader range of measurements, including the shape and features of the water itself, as well as the characteristics of the surrounding shorelines, such as tides, currents, and waves.

Bathymetric surveys provide essential data for land development projects near water bodies, such as bridge building, housing, and urban planning. By understanding the water depths and the land beneath the surface, project managers can ensure that their plans are feasible and can be executed smoothly. These surveys help identify potential challenges or constraints early in the planning process, allowing for proactive mitigation and reducing the risk of costly delays or design changes.

Bathymetric and hydrographic surveys could be used to assist marine construction or offshore projects, like the development of offshore wind farms for offshore energy.

Bathymetric and hydrographic survey services are crucial for creating nautical charts, which are specialised maps for maritime navigation, and they provide information for coastline management and safe travel on the water’s surface.

Our remote-controlled survey boats are equipped with echo sounders, GPS and total stations for precise position tracking, and drone technology for capturing point cloud data and level information. Using a remote-controlled survey boat for bathymetric surveys offers several key advantages:

  • High accuracy and comprehensive coverage of the survey area
  • Enhanced safety for surveyors, as they do not need to enter the water directly
  • Ability to access shallow or difficult-to-reach areas
  • Efficient data collection and reduced survey time

Hydrographic data collected by remote-controlled boat can be used to inform your project and ensure processes run smoothly and efficiently, saving you from any unexpected mistakes or expenses during your project.

Bathymetric surveys provide detailed information on water depths and potential underwater obstructions, enabling ships and vessels to plan their navigation safely. By identifying areas of shallow water or submerged hazards, these surveys help minimise the risk of accidents and ensure the efficient movement of maritime traffic, particularly in harbours and coastal areas.

At Lucion, we employ a range of advanced technologies to conduct bathymetric surveys.

Our preferred method for conducting bathymetric surveys involves the use of a remote-controlled survey boat, equipped with advanced echo-sounding technology. As the boat navigates the water, the echo sounder records the depths, while the positions are precisely tracked using GPS or total station. This approach offers numerous advantages, including high accuracy, comprehensive coverage, and enhanced safety for our surveyors, as they do not need to enter the water directly.

The data collected during the survey is then processed using our sophisticated survey software, which seamlessly integrates the echo sounder depths with the positional information. This allows us to generate detailed cross-sections, contour maps, and 3D models of the underwater terrain, providing our clients with a clear understanding of the water depths and the land beneath.

In addition to our remote-controlled survey boat, we also employ drone technology to capture point cloud data and level information for large areas exposed at low tide. This technique has proven particularly effective for surveys of expansive mud flats and estuaries.

Bathymetric surveys are used for a variety of purposes, including:
