电子海图显示与信息系统(ECDIS)是随当代电子计算机技术的飞速发展而发
展起来的，是继雷达／ARPA．?_后在船舶导航方面又一项伟大的技术革命，已发展成
为一种新型的船舶导航系统和辅助决策系统。它不仅能连续给出船位，还能提供
与航海有关的各种信息，有效地防范各种险情。目前世界上安装电子海图的舶船
在20万艘以上。随着各国官方电子海图(ENC)逐步完备、标准ECDIS的出现以
及IMO的认可，未来1 0年左右ECDIS将全面取代纸海图，成为21世纪航海信息综
合处理手段。(Electronic chart display and information system (ECDIS) are developed with the rapid development of modern electronic computer technology
This is the relay radar/ARPA.?Another great technological revolution in ship navigation has been developed
A new type of ship navigation system and auxiliary decision-making system.It can not only give the position of the boat in succession, but also provide it
All kinds of information related to navigation, effectively prevent all kinds of danger.The world currently installs the ship of electronic chart
Over 200,000.As the official electronic chart (ENC) is gradually complete, the standard ECDIS appear
With the approval of IMO, ECDIS will completely replace the paper chart in the next year or so, becoming the 21st century maritime information
Joint processing means.)
