Brochure, presentation & videos

The Brochure The IH Brochure provides a brief outline of the activities of the International Hydrographic Organization.  It is written for a wide audience, catering to all those that have an interest in the safe and efficient navigation of ships, protection of the marine environment and more generally to the improvement of the global economy through the provision of hydrographic services and products.  For further information, see IHO Publication M-2. ​ English ​ French      Ocean conservation focus ​ English   French   Spanish   The Presentation The IHO Secretariat has produced a generic presentation that desribes the importance of hydrography.  The presentation can be downloaded and used as needed. ​   Videos Hydrography involves measuring the depth of the water and fixing the position of all the navigational hazards that lie on the seafloor, such as wrecks and rocks. This is done mainly with specialised ships and boats operating echo sounders and sonars, but also using survey aircraft fitted with lasers. Useful information can also be derived sometimes from satellite observations. Hydrography also involves measuring the tide and the currents. The most well-known application of hydrographic information is for making the nautical charts that all mariners use for navigation. Hydrographic information is required for the safe, efficient and sustainable conduct of every human activity that takes place in, on or under the sea. These videos provide information on the importance of hydrography. ________________________________________________________
