什么是电子海图显示和信息系统（ECDIS）
ECDIS是电子海图显示和信息系统（“Electronic ChartDisplay and Information System”）的缩写，它是一种基于计算
机的显示海图和航行数据的系统。ECDIS这一词汇仅用于那些符合IMO（国际海事组织)建议的海图系统。

What is ECDIS
ECDIS is the abbreviation of electronic chart display andinformation system (ECDIS). It is a kind of computing basedinformation system
A system for displaying chart and navigation data. The termECDIS is only used for chart systems that comply with IMOrecommendations.
电子海图显示和信息系统单元与船载导航系统相连，例如全球定位系统（GPS）、回转罗盘以及测深计等，从而为屏幕上显示
的海图提供实时数据。在将电子海图显示和信息系统接口扩展到包含雷达和船舶自动识别系统之后，它还能够显示雷达覆盖
图、自动雷达标绘（ARPA）以及AIS目标。
The electronic chart display and information system unit isconnected with the shipboard navigation system, such as globalpositioning system (GPS), gyrocompass and bathymeter, so as todisplay on the screen
The chart provides real-time data. After extending the interfaceof ECDIS to include radar and AIS, it can also display radarcoverage
Map, automatic radar plotting (ARPA) and AIS target.
在电子海图显示和信息系统中主要适用两种类型的海图：向量图（ENC海图）是包含所有安全航行所需信息在内的海图的数字
数据库。向量图的特点是能够打开和关闭特定细节并设定危险区域等。除了向量图以外，还可使用光栅海图（ARCS海图），
这是纸质海图的扫描数字图像。
There are mainly two types of charts in electronic chart displayand information system: vector chart (ENC chart) is a digital chartwhich contains all the information needed for safe navigation
Database. The characteristic of vector graph is that it can openand close specific details and set dangerous areas. Besides vectorchart, raster chart (arcs chart) can also be used,
This is a scanned digital image of a paper chart.
At present, electronic chart display and information system(ECDIS) is replacing the traditional paper chart in navigation, butit always needs to have a backup ECDIS
In addition, some organizations still insist on using papercharts. We should always communicate with the relevant authoritiescarefully to understand their re for ECDIS carrierconfiguration.
目前看来，电子海图显示和信息系统（ECDIS）正在导航中替代传统纸质海图，但是总是需要有备用的电子海图显示和信息系
统，并且一些机构还是坚持使用纸质海图。应一直与有关当局谨慎沟通，了解其对ECDIS载体配置的要求。
