Hydrographic Surveys



Benchmark Surveys carry out Hydrographical Surveys, employing advanced GNSS technology and specialized boats/RIBs (Rigid Inflatable Boats) to deliver precise underwater mapping and environmental data. These surveys are pivotal for understanding aquatic terrains, evaluating water depths, and gathering essential ecological insights.

Utilising Advanced Surveying Equipment: GNSS (Global Navigation Satellite System):

Accurate Positioning: Enables precise mapping of underwater features and structures, integrated with real-time location data for efficient survey operations.

Total Stations:

Onshore Support: Aids in establishing survey control and reference points along coastlines and nearshore areas, ensuring alignment with GNSS data.

Boat/RIB (Rigid Inflatable Boat):

Stable Platforms: Provides stable platforms for deploying echosounders and underwater cameras, essential for detailed data collection in various water conditions.
