Optional use of ECDIS
Hydrographic Offices do not take any responsibility for the accuracy or reliability of
privately produced charts.
Where the vessel operates with ECS, the paper chart remains the official basis for
navigation onboard. The vessel must retain and use a full folio of up-to-date paper charts
onboard, regardless of the type of electronic charts used.
Because ECS is not intended to meet SOLAS requirements, there are no IMO
Performance Standards6 for ECS.

The International Organisation for Standardization (ISO) has developed a Standard for ECS
databases (=ECS Charts). Document ISO 19379. The Radio Technical Commission For Maritime
Services (RTCM) has developed a recommended Performance Standard for ECS (=ECS
Equipment). RTCM Paper 100-2002/SC109-STD. None of these standards are recognized by the
IMO.
