Turning maritime data into information

Mariners require information for planning and execution of voyages, assessment of navigation risk and compliance with regulation. Information should be accessible from a single integrated system. Shore-based users require information for the maritime domain of interest, static and dynamic information on vessels and their voyages, in an internationally agreed common data structure. The Usability of e-Navigation depends on harmonization of information presentation and generic standards for equipment, allowing familiarization and simplification of training. These goals will only be achieved through the introduction of a Common Maritime Information System and Data Structure. The IHO Registry has been adopted as a common baseline, providing a framework for a Common Maritime Data Structure (CMDS). Product specifications, based on data models and conforming to the IHO S-100 standard are being prepared in the fields of Aids to Navigation (AtoN), Vessel Traffic Services (VTS) and Automatic Identification Systems (AIS), for example AtoN Information exchange and the Inter VTS Exchange Format (IVEF). S-100 provides the data framework for the development of the next generation of Electronic Navigation Charts (ENC) products, as well as other related digital products required for hydrographic, maritime and Geographic Information Systems (GIS) applications. An S-100 online registry has been established for the registration, management and maintenance of the items recognised under the S100 framework. The benefits for end-users, operators and service providers of standardized exchange of information are increased efficiency, fewer errors, simpler training and common equipment and interfacing. The ways in which the CMDS will be used are still being explored. Maritime Service Portfolios provide an organised presentation of technical and operational services and the concept of a Maritime Cloud is being developed by the Danish Maritime Authority as an all-embracing information system that can serve the whole maritime sector.
