Confident Validation at Every Stage of Chart Production

7Cs Analyzer is a desktop application for validating S-57 and S-100 nautical chart datasets. It gives hydrographic offices and data producers the assurance that their datasets fully comply with the relevant IHO standards before distribution.

The application integrates seamlessly with the S-100 Data Management and Validation System (SDMS), which provides efficient workflow management across the entire data validation process. Built on the latest Nautilus ECDIS Kernel technology from Teledyne 7Cs, Analyzer brings the depth and reliability of that rendering and data-handling engine directly into the production environment.

For organisations seeking greater automation, the 7Cs Analyzer Service API makes it possible to embed the validation engine directly into existing S-57 and S-10x processing workflows via a REST API — enabling faster throughput and easier integration without compromising on compliance.
