ECDIS refers to Electronic Chart Display and Information system and this is an electronic system that is used in ships and marine vessels to help them in their navigation. ECDIS will be able to integrate navigational position and ship sensor ENCs or electronic navigational charts. From 1995 this electronic format is accepted as equivalent to paper chart by International Maritime Organization. Paper chart is replaced by this electronic chart in all marine vessels.
ECDIS can reduce marine accidents that normally result out of human mistakes that happen due to fatigue and work load. ECDIS is an automated system and does not depend on the alertness of the mariners. Moreover, with this navigational tool it is possible to get 24 hour positioning of the marine vessels. ECDIS saves the mariners from endless chart work giving them more time to handle the problems better.
