The theme for World Hydrography Day 2015 (WHD-2015) is: ‘Our seas and waterways - yet to be fully charted and explored’. A reception celebrating WHD-2015 will take place on board the Japan Coast Guard training vessel Kojima, in Port Hercule, Monaco, at 18:00 on 30 June 2015. The Hydrographers of Member States or their representatives are invited to this reception.
The theme for World Hydrography Day 2015 concentrates on the fact that much of the world’s seas, oceans and navigable waters remain unsurveyed and is intended to raise public awareness that, for example, there are higher resolution maps of the Moon and Mars than for many parts of our seas and coastal waters.
This year’s theme also provides the opportunity to encourage innovative supplementary data gathering initiatives to help obtain more useful depth data. This includes crowd-sourcing using existing ships and ship’s equipment, and developments in the analysis of satellite imagery in areas where the water is clear enough. These methods cannot replace highly accurate and thorough hydrographic surveys using specialist ships and equipment, but they can provide useful depth information where otherwise there is none available.
