What is S-100?
S-100 is a new data framework that will underpin the next generation of navigation technologies. By providing a universal standard, S-100 will improve the accessibility, compatibility and usability of hydrographic and marine data. This will include the next generation of Electronic Navigational Charts (ENCs), bathymetry, tidal information and more.
These new standards promise to enrich the way data is shared and displayed for maritime and geospatial users. By offering a much more complete picture of the maritime environment, users will be empowered to make more informed decisions based on precise, accurate and timely marine data.
The UK Hydrographic Office is at the forefront of developing S-100 solutions by developing and testing new data sets and conducting real-world sea trials; keep up to date with the latest developments by subscribing to our S-100 mailing list.

How will S-100 transform the way we navigate?
With dynamic data layers, greater granularity and improved interoperability, the next generation of S-100-enabled solutions will enhance the way decisions are made from ship to shore. From improving navigational safety to helping achieve economic and environmental efficiencies, find out more about the real-world benefits unlocked by S-100 based solutions.

S-101 – Electronic Navigational Charts
S-101 is the foundation data layer for future S-100 data sets and will replace S-57 (the format used for ENCs today).
S-101 will provide a base chart layer over which other powerful data sets will be overlaid, allowing for a much more dynamic and interoperable display of data in ECDIS.
S-102 – Bathymetric surface
S-102 is the data layer for bathymetric surface, containing high-resolution profiles of the seafloor.
With much more granular information, S-102 can open up more navigable space to transit and manoeuvre – reducing risk and complexity when navigating shallow, confined or highly congested waterways.
S-104 – Water levels
S-104 is the data layer for water levels information, helping users understand the changes in water levels for dynamic tidal applications.
When used in S-100-enabled tidal models, this data can provide more accurate tidal forecasts to support maritime navigation and port operations.
S-111 – Surface currents
S-111 is the data layer for surface currents. This provides information on the horizonal movement of water, represented by both speed and direction, which is vital for maintaining navigational safety – particularly in constrained areas.
