Q. 1090) ECDIS requirements if going to a region where vector charts are not available ?
XThe international standard for vector charts has been finalised by the International Hydrographic Organization (S-57, Version 3), and IMO adopted performance standards for ECDIS, using vector charts, in 1995 by Assembly Resolution A.817(19).
The amendments to Resolution A.817(19) state that some ECDIS equipment may operate in Raster Chart Display System (RCDS) mode when the relevant chart information is not available in vector mode.
The amendments to the ECDIS performance standards indicate which performance standards for vector charts apply equally to raster charts, and add specific specifications for raster charts, covering such aspects as display requirements, alarms and indicators, provision and updating of chart information and route planning. The amendments state that when used in RCDS mode, ECDIS equipment should be used together with an appropriate folio of up-to-date paper charts.
The MSC during its 70th sessionalso agreed a Safety of Navigation Circular on Differences between Raster Chart Display systems (RCDS) and Electronic Chart Display and Information Systems (ECDIS).
