The International Hydrographic Organization (IHO) is the inter-governmental organisation representing the hydrographic

 community. It enjoys observer status at the UN and is the recognised competent authority on hydrographic surveying and nautical charting. When referring to hydrography and nautical charting in Conventions and similar Instruments, it is the IHO standards and specifications that are normally used.

History

The IHO was originally established in 1921 as the International Hydrographic Bureau (IHB). The present name was adopted in 1970 as a result of a revised international agreement among member nations. However, the former name International Hydrographic Bureau was retained for the IHO's administrative body of three Directors and a small staff at the organization's headquarters in Monaco.

During the 19th century, many maritime nations established hydrographic offices to provide means for improving the navigation of naval and merchant vessels by providing nautical publications, nautical charts, and other navigational services. There were substantial differences in hydrographic procedures charts, and publications. In 1889, an International Marine Conference was held at Washington, D.C.

Washington, D.C.

Washington, D.C., formally the District of Columbia and commonly referred to as Washington, "the District", or simply D.C., is the capital of the United States. On July 16, 1790, the United States Congress approved the creation of a permanent national capital as permitted by the U.S. Constitution....

, and it was proposed to establish a "permanent international commission." Similar proposals were made at the sessions of the International Congress of Navigation held at St. Petersburg in 1908 and again in 1912.

In 1919 the hydrographers of Great Britain and France cooperated in taking the necessary steps to convene an international conference of hydrographers. London was selected as the most suitable place for this conference, and on 24 July 1919, the First International Conference opened, attended by the hydrographers of 24 nations. The object of the conference was "To consider the advisability of all maritime nations adopting similar methods in preparation, construction, and production of their charts and all hydrographic publications; of rendering the results in the most convenient form to enable them to be readily used; of instituting a prompt system of mutual exchange of hydrographic information between all countries; and of providing an opportunity to consultations and discussions to be carried out on hydrographic subjects generally by the hydrographic experts of the world." This is still the major purpose of IHO.

As a result of the conference, a permanent organization was formed and statutes for its operations were prepared. The IHB, now the IHO, began its activities in 1921 with 18 nations as members. The Principality of Monaco was selected because of its easy communication with the rest of the world and also because of the generous offer of Albert I, Prince of Monaco

Functions

The principal work undertaken by the IHO is:
·To bring about a close and permanent association between national hydrographic offices.
·To study matters relating to Hydrography

 and allied sciences and techniques.
·To further the exchange of nautical charts and documents between hydrographic officers of member governments.
·To tender guidance and advice upon request, in particular to countries engaged in setting up or expanding their hydrographic service.
·To encourage coordination of hydrographic surveys with relevant oceanographic activities.
·To extend and facilitate the application of oceanographic knowledge for the benefit of navigators.
·To cooperate with international organizations and scientific institutions which have related objectives.

The IHO develops hydrographic and nautical charting standards to be agreed upon by its Member States. All Member States then follow those standards in their surveys, nautical charts, and publications. The almost universal use of the standards means that the products and services from the world's hydrographic and oceanographic offices are increasingly consistent and recognisable for all seafarers and for other users. Much has been done in the field of standardisation since the Bureau (now the IHO) was founded.

Publications

Most IHO publications, including the standards, guidelines and associated documents such as the International Hydrographic Review, International Hydrographic Bulletin, the Hydrographic Dictionary and the Year book are available to the general public free from the IHO website.

The IHO publishes the international standards related to charting and hydrography, including S-57 IHO Transfer Standard for Digital Hydrographic Data, the encoding standard that is used primarily for electronic navigational chart

s. The IHO has introduced (January 2010) a new, contemporary hydrographic geospatial standard for modelling marine data and information, known as S-100. S-100 and any dependent product specifications are underpinned by an on-line registry available via the IHO website. S-100 is aligned with the ISO 19100 series of geographic standards, thereby making it fully compatible with contemporary geospatial data standards. Because S-100 is based on ISO 19100, it can be used by other data providers for their maritime related (non-hydrographic) data and information. This is already beginning to occur (2011) with various would-be data providers preparing themselves for the advent of the E-Navigation
