Standards &
Reference Frameworks.

Our survey, geospatial and metocean workflows are developed with reference to recognised industry standards and client specifications, including:

1. IHO

   IHO S-44

   Hydrographic Surveys

   The survey order sets the vertical and horizontal uncertainty, the seabed coverage and the size of feature that must be detected. We agree the order with you before the line plan.

   Applies toHydrographyDredging controlCharts & ENC

2. ASPRS

   ASPRS

   UAS / LiDAR Positional Accuracy

   Accuracy classes for drone, LiDAR and photogrammetry products, checked against independent ground control points and reported as RMSE.

   Applies toTopography & droneCoastal monitoring

3. IOGP

   IOGP / EPSG

   Geodesy & Coordinate Reference Systems

   Every dataset is delivered with its coordinate reference system and transformation named by EPSG code, so nothing is lost between contractors, GIS and CAD.

   Applies toData & digital workflowsPositioning

4. ISO

   ISO 19111

   Coordinate Referencing

   What defines a coordinate: datum, projection, vertical reference and epoch. It is the frame written into the project execution plan.

   Applies toProject systems

5. ISO

   ISO 19157-1

   Geospatial Data Quality

   Completeness, positional accuracy, consistency and lineage: the quality elements reported with each deliverable.

   Applies toProcessing & QA/QCDeliverables

6. ISO

   ISO 19901-1

   Metocean

   Metocean design and operating conditions for offshore structures: the parameters, durations and statistics a measurement campaign must support.

   Applies toMetocean & environmental monitoring

When your project has its own specification, or a national one, it comes first. We map it against these standards and show where they differ.
