Hydrography is the part of applied sciences that deals with the measurement and description of the environmental features of Lakes, rivers, seas, coastal areas, and oceans. Not only with measurement, but also it predicts its time over change, for the primary purpose of navigation and in support of several other marine activities, economic development, security and defense, scientific research, and environmental protection. In order to preserve them, World Hydrography Day is celebrated for the work of hydrographers and the importance of hydrographs.

History of World Hydrography Day

World Hydrography Day

The International Hydrographic Bureau was formed in the year 1921 for the purpose of providing a way for consultation between governments on such matters as technical standards, safe navigation, and the protection of the marine environment. After that, the name was changed to the International Hydrographic Organization (IHO) in the year 1970. In the year 2005, the IHO adopted the concept of a World Hydrography Day, which was approved by the United Nations General Assembly in the Resolution A/RES/60/30 Oceans and the law of the sea. The date chosen for World Hydrography Day is June 21, which is the anniversary of the founding of the International Hydrographic Organization.
