ABSTRACT
Data is a central part of the e-Navigation concept: “e-navigation is the harmonised collection, integration, exchange, presentation and analysis of maritime information onboard and ashore by electronic means to enhance berth to berth navigation and related services, for safety and security at sea and protection of the marine environment”
(IMO MSC 85/26 Annex 20) Based on this IMO (International Maritime
Organization) e-Navigation definition the relevant bodies are working on a harmonized data model. Consequently the discussions in the related e-Navigation Committee of the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) and the International Hydrographic Organization (IHO) have resulted in a more consolidated view on data architecture. The
various working groups have come to the conclusion that a common data structure is necessary to harmonizing the different data streams within the e-Navigation concept. While IALA was originally looking at a new “Universal Marine Data Model”, after further review and consultation with experts and the IHO it was agreed that the already established IHO concept of an “Universal Hydrographic Data Model”, known as S-100, will be the basis of the “Common Maritime Data Structure”. S-100 is based on the International Standardization Organization ISO 19100 series of geographic standards, well established in the GIS (Geographic information system) world. With that S-100 based data is compatible with data created according to the relevant ISO standards, not only within the maritime domain, but also with other GIS areas and is in support of the Spatial Data Infrastructure (SDI) initiatives in various regions of the world. This development provides the necessary harmonized platform for integrated systems. By agreeing on this
ABSTRACT: The development of e-Navigation on different levels in IMO, IALA, IHO and other arenas is starting to bring together static and dynamic data streams as well as data objects from different origination into a single e-Navigation display. In past years the static data collection found a basis in the IHO GI Register (often known as S-100 Register) and the resulting Common Maritime Data Structure. The paper will summarize the current status of development and the effects on harmonizing static data streams in e-Navigation displays. In addition to this development more recently dynamic and real time data feeds, like Virtual AtoNs, Tide Gages Data or MSI transmission from VTS stations are bringing dynamic information to the e-Navigation display. The paper will try to explain opportunities and difficulties of merging this different data streams into a single display. It will highlight the need of integrating different data layers seamlessly to increase situational awareness and gain the expected positive results on safety of navigation and environmental protection. It will also highlight that while additional data will enrich the information portfolio of the navigator, the hydrographic data will be the basis of the data streams in foreseeable future. The paper will focus on the following topics: – Current development on data in e-Navigation – Static Data Stream composition and components – Dynamic Data streams in e-Navigation – Integrated data for improved situational awareness
common GI-Registry (Geographical Information Registry) concept the maritime community prepared the ground for harmonization and interoperability of the different data streams necessary to make e-Navigation a success.
