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 - GIS and non-GIS, static and dynamic - seamlessly to increase situational awareness and gain the expected positive results on safety of navigation and environmental protection. The paper will highlight the importance of accurate and situational centric information for decision making. It will explain the "Pyramid of Competence", which graphically illustrates how data is integrated into information, digested by the mariner to increase knowledge for situation centric awareness and increase competence to make the right decisions on the bridge. It will explain the need for harmonization of data creation to allow the integration of different data streams, from shore as well as ship. It will explain the need to integrate static, dynamic and realtime data into a situation centric display, using "Human Centered Design" (HCD) as a key principle. It will also look at opportunities to automatically share Information between ship and shore for increased operational efficiency, reduced workload on the bridges and to improve the collaboration of bridge teams with shore based stakeholders, like ship owners and operators and coastal administrations, VTS and port authorities. The paper will therefore look at the IMO e-Navigation "Strategy Implementation Plan" from a ship side data point of view and its effect on navigational safety and efficiency.
