From Survey Data
to Practical Decisions.

To plan a jetty, assess river access or monitor a coastline, your team needs water depths, ground levels and water-level measurements that can be compared.

We relate the survey data to the project’s agreed reference systems and deliver the maps, profiles or models needed for the next stage, with documented quality checks.

Your Sector.
Our Field Experience.

Go straight to the support that matches your project.

Offshore Wind & Cables

Wind Farms & Cable Routes

Site and route surveys, geophysical data for UXO assessment, and survey support for cable installation, burial, repair and landfalls, through to as-built records.

Ports, Harbours & Dredging

Access, Berths & Dredging Control

Bathymetric surveys, dredging-control measurements, charts and S-57 ENCs for approach channels and berths.

Development Programmes

Banks, Authorities & Public Works

Baseline surveys and repeat monitoring in consistent reference systems for coastal and port programmes. Potential applications include the survey requirements of coastal-resilience programmes such as WACA, supported by the World Bank.

WGS supplies survey data for coastal studies and monitoring. The animation illustrates a coastal-engineering scenario to be assessed by the project’s engineering team.

Survey Companies & Contractors

Small Scopes & Nearshore

A defined nearshore survey package, specialist processing or support to set up a survey team. We agree the interfaces and deliver to your project specification.

KP 3.415One delivery chain. Or the exact stage you need.

Start with the scope. We build the response. Engage WGS for a defined task or across the survey chain, from the first brief to usable data.

Stage 1 of 5

We start from your question.

Before any method is chosen, we make sure everyone agrees on what the data must answer.Discuss this stage
  1. Your contextClient, project, constraints and budget.
  2. The questionWhat must the survey answer?
  3. Where & whenSite, access, season and programme.
  4. Expected resultWhat you receive, and to what accuracy.
  5. Intended useDesign, dredging, permits, monitoring or a decision.

Stage 2 of 5

A method you can approve before anyone mobilises.

The method, resources, assumptions and budget are agreed before mobilisation.Discuss this stage
  1. Method statementHow the work will be done, step by step.
  2. Mission plansLine plans, coverage and sequencing.
  3. Positioning & datumControl, vertical reference and tide.
  4. Equipment proposalFit-for-purpose sensors, availability and sourcing.
  5. Programme & budgetA realistic schedule and mobilisation plan.

Stage 3 of 5

The right people and systems, assembled for your scope.

Our directors combine technical leadership with field involvement, with specialists mobilised for each assignment.Discuss this stage
  1. Survey teamParty chiefs, surveyors and processors. CVs on request.
  2. EquipmentSensors, positioning and spares, rented or purchased.
  3. Vessel & interfacesPlatform, mounting, power and communications.
  4. ReadinessCalibrations, checks, HSE and permit support.

Stage 4 of 5

Quality checks throughout acquisition.

We track coverage, sensor performance and data quality as the work progresses.Discuss this stage
  1. Field supportOn deck or online, with the client and the crew.
  2. Survey controlPositioning, calibrations and real-time QC.
  3. AcquisitionBathymetry, geophysics, metocean and topography.
  4. Daily reportingProgress, coverage, issues and decisions.

Stage 5 of 5

Data prepared for your next stage.

Processed, checked and documented for the agreed engineering, mapping or monitoring use.Discuss this stage
  1. ProcessingHydrographic and geophysical processing.
  2. QA/QCDocumented checks and processing history.
  3. Charts & modelsDTMs, charts, ENCs, mosaics and anomaly maps.
  4. ReportingClear reports that decision makers can read.
  5. HandoverDocumented GIS and SSDM datasets.

The practical value is in the detail: method and equipment selection, positioning strategy, field readiness, quality control and agreed deliverables before mobilisation.

What You Receive.

Charts, models, structured datasets or technical reviews: outputs and supporting documentation are agreed around your assignment.

  • Charts & ENCBathymetric charts and S-57 ENCs produced from survey data and delivered to the project specification.
  • 3D terrain modelsGridded DTMs, point clouds and volume computations.
  • Sonar mosaics & targetsSide-scan mosaics, contact lists and seabed classification.
  • Magnetic & UXO mapsAnomaly maps and target lists to support UXO assessment and investigations of buried infrastructure.
  • PhotogrammetryDrone photogrammetry, orthophotos and 3D models.
  • GIS, SSDM & reportsStructured GIS and SSDM datasets, metadata and clear reporting.

Local Partnerships.
Long-Term Survey Support.

For clients who need regular survey services, we are open to setting up a local survey company together with a local partner. We start from the project needs and build the team, equipment and technical support around them.

The aim is to recruit and train local people, deliver reliable survey services and build a lasting presence, supported by the WGS technical network. From a first assignment to a dedicated local team, we can explore the right approach together.
