What is Hydrography?
Hydrography is the science that measures and describes the physical features of the navigable portion of the Earth’s surface and adjoining coastal areas. It is also important for economic developments, defence and security, scientific research, and environmental protection.
The International Hydrographic Bureau (IHB) was established in 1921. The name of the organisation was changed to the International Hydrographic Organization (IHO) in 1970.
