Are All Electronic Chart Navigation Systems Considered ECDIS?
Not all navigation systems that use electronic charts can be considered an ECDIS. A navigation system needs more than just the ability to read digital charts to be considered an ECDIS. It needs to incorporate other information into electronic navigational charts, or ENCs, like global positioning system data, or GPS data, fathometer data and radar data in assisting navigators plotting courses and voyage routes. Other information and data can be used to be layered into the usual digital navigation information as long as they all comply to standards and regulations of the IMO. This means that only digital navigation systems that use IMO compliant data are to be considered ECDIS.
