Bathymetric Surveys

Unrivalled data for outstanding results - choose our bathymetric survey service for an in-depth understanding of water bodies.

By assessing the depth and topographic relief of water bodies, bathymetry aims to elucidate aspects related to maritime exploitation and developments. Topo3D plays an essential role in topographic surveys of the seabed and flood zones, positioning itself as a key player in this field. The company demonstrates its bathymetric expertise by assisting clients and providing pertinent information for construction and renovation projects involving dikes, dams, pillars of engineering structures, retaining walls, marinas, as well as municipal and industrial outfalls.

DIAGNOSTICS

To ensure the successful detailed design of marine construction projects, Topo3D offers multidisciplinary surveys (bathymetry + lidar) providing complete under and above water site information. Whether for small or large-scale projects, we meet our customers’ requirements by carrying out subsurface surveys, which can be enhanced by surface surveys (lidar or photogrammetric) on request. Our products include the creation of bathymetric plans, detailed cartographic representations of the bottom of lakes or bodies of water to visualize the configuration of underwater relief.
