IHO Standards
  The International Hydrographic Organization is an intergovernmental consultative and technical organization with a mission to “ensure the provision of adequate and timely hydrographic information for world-wide marine navigation and other purposes”. The Office of Coast Survey is an active member of the International Hydrographic Organization (IHO) and participates in IHO committees and working groups establishing, revising, and following IHO standards.

The 80 countries that belong to the International Hydrographic Organization coordinate efforts to chart the world’s navigable waters. Through the IHO, they establish standards that national hydrographic offices use to guide their development of particular specifications for hydrographic surveying, chart production, and other navigation services.

As a member of the IHO, Coast Survey participates in the organization’s committees and working groups, bringing the U.S. perspective to the development of IHO standards. Those standards, in turn, guide the development of NOAA’s hydrographic and cartographic specifications.

In 2009, NOAA led the U.S. delegation presenting the U.S. ratification of the Protocol of Amendments to the Convention on the International Hydrographic Organization
