Importance of Hydrography
Definition of Hydrography Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defence, scientific research, and environmental protection. In addition to supporting safe and efficient navigation of ships, hydrography underpins almost every other activity associated with the sea, including: - resource exploitation - fishing, minerals,.. - environmental protection and management - maritime boundary delimitation - national marine spatial data infrastructures - recreational boating - maritime defence and security - tsunami flood and inundation modelling - coastal zone management - tourism - marine science
World Hydrography Day
Celebrated on 21 June, World Hydrography Day is designed to raise awareness about hydrography and how it plays a role in improved knowledge of the seas and oceans.

IHO Crowdsourced Bathymetry Initiative
The International Hydrographic Organization (IHO) has a long history of encouraging the collection of crowdsourced depth data to help improve humanity’s understanding of the shape and depth of the seafloor. For over a century, maps of the ocean floor were created from depth measurements collected by vessels as they journeyed across the oceans. These “passage soundings” enabled the creation of progressively more detailed seafloor maps and digital data grids. Recently, systematic surveys with specialized ships have contributed to greatly increasing available data. Unfortunately, despite the multitude of data that has been collected, to this day only 25% of the world’s ocean depths have been measured; the rest of the data used to compile seafloor maps are estimated depths.

E-Navigation and GMDSS
Introduction E-navigation is defined as “the harmonized collection, integration, exchange, presentation and analysis of marine information on board and ashore by electronic means to enhance berth to berth navigation and related services for safety and security at sea and protection of the marine environment.” It is intended to meet present and future user needs through harmonization of marine navigation systems and supporting shore services.
