The IHO S-100 family of product specifications is gaining real momentum. ECDIS vendors, port systems, and maritime software are updating their stacks to ingest S-100 encodings — moving away from bespoke formats toward a shared, machine-readable standard for currents, water levels, waves, and more.

Calypso Science has been part of that transition. We participated in the LINZ S-100 test bed, working through real-world export, delivery, and consumption of hydrodynamic model output in standard form. That work validated our pipeline end to end: we can now export any of your model forecasts to S-100 — typically S-104 Water Level (Edition 2.0) on a regular grid, and S-111 Surface Currents on an irregular node layout (DCF 3), with full metadata for operational use.

To show what that looks like in practice, we put together the SeaScope S-100 Demo Portal — a public map with a selection of our models already encoded and ready to explore.
