Additionally to the short answer given by GordMay I guess I should explain ECDIS a bit more.
ECDIS is an electronic navigational tool which improves significantly the safety
. That means not only to interface between positioning systems and the sea chart. That is performed by other Electronic Charts
Systems as well. Rather the use of official Electronic Navigational Charts
(ENC) and the functionalities (1) which can be employed when sailing with those charts are the main improvement compared to traditional navigation
The standard for ECDIS is been defined by IMO and the standards for ENC
are defined by IHO. Complex test and control routines guarantee high technical standard and permanently updated charts.
(1) e.g. you can specify a minimum required water depth
and the system will alert you when getting too close to that water
depths line, or the next deeper line if the current ENC
doesn't support your request. That make sure that you are always on the safe side. It will work too, if the presentation for those water depths line has been switched off. Means ECDIS employs very much the magic of vector data.
