Prepared for new standards

S-100 is important to the Danish Geodata Agency to ensure we are prepared for the new standards and can continue to provide the best products and services to end users, in particular S-101 Electronic Navigational Charts (ENCs).

Topics for discussion included:

  • Interoperability of S-100 products
  • Registration of data in the GI Registry
  • S-102 – Bathymetric Surface
  • Experiences of developing S-100 test products
  • Amendments to the S-100 data model
  • Data transfer and distribution
  • Continual maintenance of S-100 to meet the needs of the wider user community
  • Increased Stakeholder engagement


Facts about S-100 – Universal Hydrographic Data Model

S-100 is the IHO standard for the Universal Hydrographic Data Model. It provides the data framework for the development of the next generation electronic navigational charting products, as well as other digital products required by the hydrographic, maritime and GIS communities.
The primary goal of S-100 is to support a greater variety of hydrographic-related digital data sources, products, and customers. Some of the advantages include:

  •  Aligns with mainstream GIS
  • New components not developed in isolation
  • Easier use of hydrographic data beyond Hydrographic Offices and Electronic Chart Display
  • and Information System (ECDIS) users
  • Plug-and-play updating of data, symbology and software enhancements
