Centerline provides high-precision bathymetry services to map and measure underwater topography for industrial and civil applications. By utilizing Unmanned Surface Vehicles (USVs) equipped with single-beam and dual-frequency echo sounders, we capture detailed profiles of the seabed and lake-bottom structures. This autonomous approach provides a safer and more cost-effective solution for mapping complex aquatic environments.

Our bathymetry mapping process is designed to support infrastructure planning, environmental monitoring, and resource management. We utilize shallow-draft hulls that allow for seamless data collection in remote lakes, rivers, and coastal waters. This technology enables us to deliver high-resolution depth measurements and sub-bottom profiling, which is essential for identifying sediment accumulation and verifying as-built conditions.
Modern hydrographic surveying requires more than just depth soundings; it requires a comprehensive understanding of the underwater environment. Our team utilizes advanced USV technology to conduct systematic surveys that eliminate the safety risks and logistical costs of manned vessels. This allows us to work in hazardous or restricted areas, such as industrial tailings ponds, while delivering the high-density data required for modern engineering projects.
By tying underwater data into land-based GPS coordinate systems, we create a unified model of the site. This allows engineers to see exactly how underwater slopes interact with the shoreline, which is critical for bridge foundations, pipeline crossings, and intake structures. Our focus is on delivering a seamless transition from land to water, providing a complete topographic picture of your project area regardless of water depth.
Our USVs have a very shallow draft, allowing them to navigate waters just inches deep. For areas where the boat cannot go, we use manual GPS “wading” surveys.
Yes. Using dual-frequency sonar, we can identify the top of the soft sludge and the hard ground beneath it for precise volumetric calculations.
Yes. Our crew stays on the shore while the autonomous vessel does the work, eliminating the risk of personnel being on the water in hazardous environments.
We provide detailed 3D surface models, AutoCAD-ready files, and cross-sections that show water depth, sludge thickness, and bottom elevation.
Yes. We have a national reach and perform a significant portion of our bathymetry work in Newfoundland and across the rest of Canada.
