The IHO Website is being moved to a new service provider - disruptions may occur.
Thank you for your understanding.
A principal Aim of the IHO is to ensure that all the world's seas, oceans and navigable waters are surveyed and charted.
The Mission of the IHO is to create a global environment in which States provide adequate and timely hydrographic data, products and services and ensure their widest possible use.
The Vision of the IHO is to be the authoritative worldwide hydrographic body which actively engages all coastal and interested States to advance maritime safety and efficiency and which supports the protection and sustainable use of the marine environment.
