The most important issue of the 4th Extraordinary International Hydrographic Conference was the global availability and quality of ENCs (Electronic Navigational Charts), which are the only official electronic charts published by maritime countries according to the SOLAS (Safety Of Life At Sea) convention of the IMO. A fairly complete portfolio of ENCs is expected by IMO in the very next years, as being necessary to suit the mandatory carriage of ECDIS on most commercial vessels, which has passed MSCs approval recently.
