Underwater Survey — how the dataset stays usable
Diverless data capture for precise underwater structures
Note: This post is a news entry point to our Survey & Mapping service. Method, accuracy record and deliverables live on the service page:
Status: The service is currently being developed as a regular offering; pilot projects and preliminary enquiries are already possible.
Reliable decisions in hydraulic engineering, infrastructure planning or environmental monitoring depend on accurate knowledge of structures below the waterline. Conventional methods often reach their limits — especially in poor visibility, at greater depths or in hard-to-access locations.
ScanSustain provides diverless underwater survey and mapping services that enable precise, repeatable and objective data capture.
Why diverless underwater surveying?
Diverless methods offer clear advantages over traditional approaches:
- improved operational safety
- repeatable measurement results
- deployment in low-visibility conditions
- objective, data-driven documentation
ROV-based systems enable controlled acquisition of underwater structures without direct intervention or diver-related constraints.
Our methodology
ScanSustain combines multiple data streams into an integrated survey approach:
- Navigation: position-accurate referencing of all recordings
- Sonar: capturing structures, geometry and relief forms
- Video: visual documentation for interpretation and assessment
This combination enables accurate mapping of underwater areas, including the location of structures, sediment features or natural formations.
Typical applications
Our underwater survey and mapping services are commonly used for:
- baseline surveys of underwater structures
- hydraulic engineering and infrastructure projects
- repeat surveys and monitoring programmes
- environment and waterbody projects
- project and construction controls
The resulting datasets remain usable over time and allow direct comparisons across multiple survey campaigns.
Documentation & deliverables
ScanSustain delivers structured, traceable results such as:
- location and object maps
- position-referenced video and sonar datasets
- clearly compiled reports
These deliverables provide a reliable basis for planning, evaluation and decision-making.
ScanSustain — Precision below the surface
With diverless underwater surveying and mapping, ScanSustain delivers dependable data where direct visibility is not possible.
