Official Electronic Navigational Charts – ENCs – are vector-based electronic charts, designed to meet the relevant chart carriage requirements of the IMO Safety of Life At Sea (SOLAS) convention. During installation into the ECDIS system ENC files are converted to the SENC (System Electronic Navigational Chart) data with similar contents. ENCs are produced by Governmental Hydrographic offices of different nations, each Hydrographic Office is responsible for production and updates ENC for its territory.
