Characteristics
The rapid development of computers and navigational instrumentation has come together in one unit in the form of ECDIS. The original paper charts used for navigation have now been replaced by electronic charts which can be displayed on a monitor and manipulated by zooming, scrolling, etc. Navigation can thus be carried out by manipulation cursors on a monitor rather than using parallel rules and compasses on a paper chart.

With developments in the Global Positioning System (GPS) positions accurate to within tens of meters can be determined. This is combined with the ability to show radar images on computer monitors, resulting in the display of charts and radar images on one screen, all co-located by means of the very accurate navigational system. This is the basic concept of ECDIS.
Similar ECDIS-type equipment can be configured for use on fishing vessels even though they are not required to carry type approved ECDIS models. Such equipment can record fishing information as well as official charts.
