The S-100 standard, the full name of which is the Common Universal Hydrographic Data Model for Hydrographic Data Model (S-100), is a framework document developed by the International Hydrographic Organization (Iho). It provides a modern marine Geographic Spatial Data standard designed to provide the basis for hydrographic, maritime, and Geographic Information System (GIS) digital products and services, while lowering the threshold for the use of marine mapping data and technology in different professional fields.

• Standard system for products developed on the basis of the S-100 standard: IHO assigns S-1XX numbers to products developed on the basis of the S-100 standard. The S-101 to S-199 number range is assigned to products developed by IHOs, while higher numbers are assigned for use by other organizations. The following are part of the numbering range of the S-100 product specification system:
  • International Hydrographic Organization (IHO) (S-101 to S-199)
  • International Aids to Navigation Association (IALA) (S-201 to S-299)
  • Intergovernmental Oceanographic Commission (IOC) (S-301 to S-399)
  • Inland Water Electronic Chart Coordination Group (IEHG) (S-401 to S-402)

In the above S-100 product standard system, the main standards include S-101, which provides the basic base map of Electronic Chart. S-102, which regulates the Elevation Data of submarine water depth surface, and S-104, which focuses on the tidal level information of navigation water level.

Through these numbering ranges, the S-100 standard provides a unified product development framework for multiple organizations, helping to ensure interoperability and standardization of data products.

S-100 vs. S-57

S-100 product standard system is often regarded as the replacement, update and upgrade of S-57 series specifications , because:

• S-57 generally refers to a series of product specifications, including S-57 (data), S-52 (display), S-58 (inspection), and S-63 (encryption). The formulation of S-57 series standards can be traced back to the 1980s. With the development of science and technology, after 40 years, S-57 is no longer suitable for today's Electronic Chart product needs.
• In 2001, IHO initiated the development of the S-100 as a complete update to the S-57 family of standards. By retaining the core content of S-57 series specifications, new data structures are developed on this basis, and the ways of data sharing and display are enriched. The S-100 series specifications make it easier to integrate hydrographic data and applications into Geospatial Solutions.
• Compared with S-57, S-100 series has the advantages of more flexible maintenance system, more suitable for future development of data needs, better data model scalability and more standard development.
