National Hydrographic Office


The National Hydrographic Office (NHO) is a government organization responsible for conducting hydrographic surveys and publishing nautical charts and other navigational publications. These surveys are essential for safe navigation and are used to determine the nature and shape of the ocean floor, including depth, seabed material, and the presence of hazards such as wrecks, rocks, and shoals. The NHO also provides tide and current information, as well as details about coastal features like lighthouses, buoys, and landmarks. The data collected by the NHO is crucial for various maritime activities, including shipping, fishing, offshore exploration, and marine research. The NHO works closely with international organizations like the International Hydrographic Organization (IHO) to ensure the standardization and compatibility of hydrographic data worldwide. It also plays a key role in the development and implementation of new hydrographic technologies and methodologies.
