SSSI Hydrography Commission News – May 2020

April 30, 2020
World Hydrography Day

World Hydrography Day, 21 June, was adopted by the International Hydrographic Organization(IHO) as an annual celebration to publicise the work of hydrographers and the importance of hydrography.

"Hydrography – enabling autonomous technologies".

The IHO’s theme for 2020’s World Hydrography Day highlights the pivotal role of hydrography in autonomous technologies. Autonomous platforms such as autonomous surface vehicles (ASV), autonomous underwater vehicles (AUV), Satellite based bathymetry and Lidar-equipped unmanned aerial vehicles (UAV), such as drones can be used to conduct hydrographic surveys. In doing so, hydrography provides a testing ground for these technologies, while at the same time increasing the coverage of properly surveyed areas. As a knock-on effect, these initiatives will pave the way for the development of safe, secure and environmentally sound Maritime Autonomous Surface Ships (MASS) operations under the auspices of the IMO, which also require certified up-to-date hydrographic information in order to be implemented.

SSSI is pleased and proud to celebrate World Hydrography Day 2020 and extend to all hydrographers a very heartfelt thanks for all the work you do!
