A need for a navigational chart aroused as man started to navigate through waters and the importance of hydrography came into play since then. Hydrography involves a process, from collecting data in the field to the preparation of the chart in accordance with the highest international standards and contributes immensely to the economic development of a country. The International Hydrographic Organization (IHO), which has 94 member countries including Sri Lanka, coordinates hydrographic activities worldwide through 15 Regional Hydrographic Commissions (RHCs). The IHO was founded in Monaco on 21st June 1921.
