Hydrographic Surveys

Gridmark Survey offer a Bathymetric survey solution suitable for ports, rivers, lakes, reservoirs and coastlines.

Using a single beam echo sounder mounted on a HyDrone remote controlled vessel then combined with RTK GNSS or a Robotic Total Station, it is possible to determine the location and exact depth in any watercourse.

Our surveys can be commissioned for projects like flood risk analysis, river erosion solutions and marina expansions.

The data is available in real time and can be exported and all available coordinate or surface formats.
