7Cs Analyzer, 7Cs Analyzer Service API

7Cs Analyzer is a desktop application used for validating S-57 and S-100 datasets. It provides data producers with the confidence that their datasets comply with the relevant IHO standards.

The tool offers seamless integration with ENC Designer (S-57 datasets only) and the new S-100 Data Management and Validation System, SDMS. SDMS provides efficient workflow management to the data validation procedure using 7Cs Analyzer.

The software is based on our latest ECDIS Kernel technology, called Nautilus. Therefore we consider it to be propelled by Nautilus.

To improve automation of the validation process, customers can integrate the 7Cs Analyzer validation engine into their existing S-57 / S-10x processing workflows, by means of the new 7Cs Analyzer Service API. 

7Cs Analyzer was developed in cooperation with Nautical Dimensions, Australia.
