Electronic Chart Display and Information System (ECDIS)

An Electronic Chart Display and Information System (ECDIS) is a geographic information system used for nautical navigation that complies with International Maritime Organization (IMO) regulations as an alternative to paper nautical charts. ECDIS allows for monitoring of a ship's position in real-time throughout the voyage and integrates information from GPS, Gyro, Radar, ARPA, AIS and other navigational equipment into a single display.
