Abstract

The Electronic Chart Display and Information System (ECDIS) has been defined by the International Maritime Organization (IMO), in cooperation with the International Hydrographic Organization (IHO), as a new, world-wide standardized navigation system. It is based on an object-structured vector data base, allowing GIS functionality. The structure of ECDIS is explained, and it is shown how ECDIS, linked to GPS/DGPS positioning, boosts integration of navigational bridge functions. An overview of the standards developed for ECDIS is given and their rationale explained. In particular, the requirements of precise navigation result in the need for high accuracy surveys and a demand for using a single, unified horizontal datum for unique geographic reference. Likewise, a harmonization of vertical Chart Datums is needed. Some problems resulting from this are discussed.
