Electronic navigation, although still relatively new, is becoming increasingly more common, particularly onboard commercial vessels. This handbook offers a tremendous amount of technical information about how the different charting systems operate and provides answers to the most commonly asked questions regarding electronic charts (ENC, RNC, DNC) and electronic chart systems (ECDIS, RCDS, ECS). The book will be of specific interest to those who need to know about selection, implementation, operational use, benefits, and management of ECDIS and ECS systems, but do not need to know all the technical details of how a ECDIS/GIS actually 'works', technically.
