- Delivery formats
BODC handles a wide range of marine data sets collected and provided by numerous organisations from the UK and around the world. Data standardisation, both for parameters and file format, is essential for their professional management. Details of our methods of standardisation both present and historical are provided here.
All data in our National Oceanographic Database (NODB) or the project database maintained by BODC are held in our standard units and are assigned parameter codes as described in the BODC Parameter Dictionary.
Standardised file formats
BODC distributes data in various standard formats
- BODC request (ASCII) format
A BODC output format designed to handle most types of data held by BODC.
- Ocean Data View (ODV) format
A BODC (SeaDataNet) ODV format designed to handle most types of data held by BODC.
- QXF (a netCDF) format
QXF is a BODC defined subset of the binary format netCDF.
- Climate and Forecast (CF) netCDF format
CF-compliant netCDF conforms to CF guidelines and recommendations on how to place usage metadata — information about data — within a netCDF file.
- AXF format
BODC no longer distributes data in AXF format — AXF details are provided for historical files.
- GEBCO grid formats
Export formats used by the British Oceanographic Data Centre to distribute the General Bathymetric Chart of the Oceans (GEBCO) gridded bathymetric data sets.
Bespoke sea level formats
- National Tidal & Sea Level Facility (NTSLF) format
NTSLF format is an ASCII output format for data from the UK Tide Gauge Network
- European Sea Level Data (ESLD) format
ESLD format is an ASCII output format for data from the European Sea Level Data portal
- World Ocean Circulation Experiment (WOCE) netCDF format
WOCE netCDF details are provided for historical files
Vocabulary content governance
Initiatives such as SeaDataNet and MarineXML are working toward the International Organization for Standardization (ISO) 19115 standard. They are using code lists and controlled vocabularies to regulate the population of metadata.
Vocabulary content governance is very important in order to stay up-to-date and in sync with ongoing developments. Therefore, a combined SeaDataNet and MarineXML Vocabulary Content Governance Group (SeaVoX) has been set up.
