Solutions for S-100 Transition & Integration
The International Hydrographic Organization (IHO) developed the S-100 Universal Hydrographic Data Model (S-100) to align with the future demand for digital products and services.

Dual Fuel and How to Get There
Dual Fuel Mode refers to a system’s ability to process data from both charting formats, S-57, and S-101. All ECDIS systems must have Dual Fuel capabilities by 2024 to support the IHO’s shift towards full S-101 standard compliance by 2030.
