ECDIS is primarily a navigation device, but the core elements to ECDIS, as seen from the perspective of hydrography, are ENCs - Electronic Navigational Charts. These data sets based on EHO S-57 standard are the data products carrying hydrographic information by means of a catalogue containing specific objects and attributes created for the storage of hydrographic and navigationally significant data. The reality of ECDIS in terms of information and functionality is: The content of the chart data base is up to date only shortly after shore contact. The chart display widely imitates the look and feel of paper charts and is limited to 2D birds eye view. ECDIS does not make use of full diversity of hydrographic information available. ECDIS does not satisfactory incorporate the 'fourth dimension': time. The integration of added navigation information is limited to superimposition. ECDIS devices are mostly carried in addition to paper charts. The primary objective in the development of the new IHO Geospatial Standard for Hydrographic Information is to support enhanced data products beyond the limited scope of the current ENCs, improve product consistency, provide better version control and create a 'plug and play' model for data updates. The S-100 model and future S-101 product specification for next generation ENCs is to ensure a continuity of service, providing a manageable transition while introducing an improved environment for users and ensuring a smooth transition between data standards.
