International Hydrographic Organization
The IHO was established in 1921 as the International Hydrographic Bureau (IHB). The present name was adopted in 1970 as part of a new international Convention on the IHO adopted by the then member nations. The former name International Hydrographic Bureau was retained to describe the IHO secretariat until 8 November 2016, when a revision to the Convention on the IHO entered into force. Thereafter the IHB became known as the "IHO Secretariat", comprising an elected Secretary-General and two supporting Directors, together with a small staff of 17, at the Organization's headquarters in Monaco.

In contrast to the US government, all of whose creative work is placed into the public domain, British government policy requires agencies such as the UKHO and the Ordnance Survey to be self-funding through the sale of the information they create. The Hydrographic Office therefore actively protects the copyright of all of its data including paper charts, electronic charts, tidal data and other data and has been known to take measures to ensure that its copyrighted information is used appropriately.
