Brief History Contd...

7. On the International scenario, India is an active and influential member of the International Hydrographic Organisation (IHO), Monaco and has representation on its various committees. INHD fully supports the work programmes of the IHO, especially in developing regional expertise, and capacity building in Hydrographic Surveying and nautical charting in the littoral region. With experience and expertise in Hydrography coupled with modern instrumentation, India plays an important role on the International Hydrographic scene, where it promotes India's maritime interests notably on the issues of standards for global charts, Strategic Planning and Work Programmes of IHO and Global Maritime Distress and Safety Services (GMDSS). The Department plays an active role in promoting hydrographic cooperation in the region through the North Indian Ocean Hydrographic Commission (NIOHC) of the IHO.

8. Since past many decades National Hydrographic Office, Dehradun is involved in systematic and standardised collection of geo-referenced data pertaining to coastal configuration, depth of the sea in the areas of National Interest, seabed composition, wreck investigations, tide current and physical properties of water column, aids to navigation, marine traffic, fisheries etc. The data collected by the fleet of survey ships, is subjected to standardised processing for creation of databases to be used in marine environment preservation, exploitation of marine resources, definition of maritime boundaries (Law of the sea implementation) and scientific studies on sea and coastal zone. Periodic updating of these databases continues through fresh surveys. The office produces standard navigational charts and nautical publications as per conventions of the International Maritime Organisation (IMO) and the International Hydrographic Organisation (IHO). Since past few years, this department has been producing digital charts in the form of Electronic Navigation Charts (ENC) in accordance with specifications of IHO for use in the Electronic Navigation Chart Display and Information System (ECDIS) through a licensing system. The ENC, the database for ECDIS, is of high significance for the GIS application in the marine and scientific fields related to coastal, near shore zones, seas and oceans and are widely used by Mariners, Researchers, Scientists, Cartographers, Environmentalists, etc.

9.The Chief Hydrographer to the Govt. of India is the coordinator for charting Area "J" in the North Indian Ocean. The various nautical/navigational products produced by the Department are made available to the mariners through the Naval Chart Depots located at Mumbai and Visakhapatnam. The increasing usage of the products and services by the users is ample proof of the relevance of the Organisation.

10. Hydrographic products and services have gone beyond the traditional scope of marine transport. Path breaking advances in Ocean Technologies in the past few decades, gave an impetus to industrisalisation and exploitation of the Coastal and Offshore Zone. This in turn also led to environmental concerns for these zones. All these developments have added many new dimensions to value added hydrographic products and services. Beyond the traditional 'Safety of Navigation'; demands on Hydrography today, include Engineering Studies for Coastal infrastructure development, Offshore hydro-carbon and Ocean energy exploitation, Pollution Control and a wide range of Coastal Zone Regulation issues. The Indian National Hydrographic Office, Dehradun, has been contributing significantly to the march of India's coastal development by meeting these survey demands to world standards. Thus, besides providing the standard products and services for the marine community, the Department also provides customised products to various national agencies and research organisations related to ocean sciences and offshore resource exploration and exploitation. The thorough examination of wrecks along the coastal waters of India has also been one of the major activities undertaken by the Department. The Department actively assists in sea truthing programmes at sea for various scientific organisations.

11.The Indian Naval Hydrographic Department under Vice Admiral Vinay Badhwar, NM the Chief Hydrographer to the Govt. of India, is committed to the national obligation for greater marine safety surveys under international conventions and national regulations, and providing quality value added products and services to meet the diverse users needs towards sustainable development of the oceans in the 21 st century.
