ENC vs. chartplotter
Producers of electronical navigational charts for chartplotters can get access to chart data from the Norwegian Mapping Authority, to be used in their software. These chart solutions are not authorised navigational charts.
There is a difference between official electronical navigational charts (ENC) used in an ECDIS (Electronic Chart Display and Information System) and electronical charts used in chart plotters. Carriage of up-to-date official charts (ENC) is an obligation for the regulatory (SOLAS) shipping. Only ENCs fulfil these carriage requirements.
