Global traffic data has been evaluated in relation to the coverage of ENC and eleven specific ship routes, representative for global merchant shipping, have been analyzed in further detail. Overall, the ENC coverage was found to be extensive, with 82 ? 94% coverage for SOLAS ships, and 28 ? 100% coverage along selected routes. Furthermore, it has been demonstrated how the coverage of ENCs could be taken into account when assessing the effect of ECDIS for safer ship navigation and associated cost effectiveness.}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Electronic Navigational Chart (ENC), Electronic Chart Display and Information System (ECDIS), Global Coverage of ENC, Shipping, Marine Navigation, Ships Routes, SOLAS Convention, Net Cost of Averting a Fatality (NCAF)} }
