Refers to the navigation electronic chart system that meets the relevant international standards. It is a special geographic information system (GIS) with computer as the core, connected with positioning, sounding, log, radar and other equipment, and based on ENC (Electronic Chart/Waterway Chart), which comprehensively reflects the ship's driving state and provides various special tools for ship drivers to query, calculate and record information.

In order to facilitate understanding, I drew the original definition in the form of mind map, as follows:
According to the definition, according to the different devices accessed by ECIDS, the corresponding information can be displayed in layers on the hardware display screen. Help ships sailing on the vast water to understand the surrounding situation. In essence, the electronic chart system is a computer loaded with electronic charts, which provides more abundant functions through various access devices. For example, accessing DGPS (or GPS) can realize the functions of positioning and speed measurement; Generally speaking, ECDIS will also be equipped with AIS (Automatic Ship Identification System) to let you see the situation of nearby ships and so on.
As mentioned earlier, ECDIS is a computer loaded with ENC and other contents. As a computer, it has many similarities with PC in design.
Interactive mode: keyboard and mouse.
In order to save operating space, the keyboard and mouse are generally integrated (there are also keyboard and mouse similar to PC), and the mouse is operated by only one wheel in most cases. Some brands will design more complicated keys around the keyboard and mouse to improve the operation efficiency.
There are also ECDIS that can directly click on the screen, which may be limited by factors such as operating environment and cost, and is rarely used at present.
Display mode: A display screen similar to a computer monitor is generally embedded in the console with the host.
Contents displayed by different electronic charts:

By looking up the information, in contrast, Furano Electric Company has the most detailed description of ECDIS, and interested friends can go to Furano to find out.
