ECDIS Voyage planning
established in S57 Edition 3 and other IMO and IHO
specifications. A common source of error exists in the
underlying data from which the ENC is derived. Such
errors are a result of the ‘inappropriate’ scaling of the
chart data caused by: survey errors; horizontal datum
errors and uncertainties; unreported changes; and
obsolescent survey technology.
