What distinguishes ECS from ECDIS?

The distinguishing factor that sets ECS apart from ECDIS is that ECS, or Electronic Chart System, is a civilian navigational aid that does not comply with the stringent international standards set for charting under the ECDIS framework. While ECDIS is designed to meet international maritime regulations and requires the use of official nautical charts that are updated to specific standards, ECS can be used for navigation without adhering to these requirements. ECS can still serve as a useful navigational tool, but its lack of compliance with international charting standards means that it may not provide the same level of reliability and safety as ECDIS.

In contrast, ECDIS systems must use vector charts that are compliant with the International Hydrographic Organization (IHO) standards, passing additional verifications and ensuring data consistency for safer navigation. This distinction is crucial for understanding the differences between these two types of electronic navigation systems and their applications in maritime operations.
