Development of IHO S-100 The New IHO Geospatial Standard for Hydrographic Data

摘要

The International Hydrographic Organization (IHO) is an intergovernmental consultative and technical organization established in 1921 to support the safety of navigation, and to contribute to the protection of the marine environment. IHO Special Publication 57 (IHO S-57) is the IHO Transfer Standard for Digital Hydrographic Data. It is the standard intended to be used for the exchange of digital hydrographic data between hydro-graphic offices, and for the distribution of hydrographic data to manufacturers, mariners and other data users (e.g., environmental management organisations). It was developed so that the transfer of all forms of hydrographic data would take place in a consistent and uniform manner. To date, S-57 Edition 3.0/3.1 has been used almost exclusively for encoding Electronic Navigational Charts (ENCs) for use in Electronic Chart Display and Information Systems (ECDIS). However, there are changing requirements, customers and technology for hydrographic data and as S-57 is intended to support all types of hydrographic data, not solely ENCs, it needs to be expanded in order to accommodate these new requirements.
