Abstract

The Electronic Chart Display and Information System (ECDIS), in conjunction with other recent technologies such as Radar and Automatic Information System (AIS) has practical benefits to facilitate safe navigation and bridge watchkeeping. The ECDIS capability however is suffering from ongoing issues including Electronic Navigation Chart (ENC) data encoding inconsistencies, differences between the content shown on paper charts and the corresponding ENC, overlapping and conflicting ENC coverage and the interpretation and application of the IHO’s S-52 Presentation Library to display ENC symbols. This paper addresses the International Hydrographic Organization’s (IHO) effort to collect, analyze and resolve these problems so that they can be addressed by the appropriate agencies and organizations in order to maintain safety of navigation.
