IHO-Nippon Foundation GEOMAC Project

The IHO-Nippon Foundation Cooperation Project has been providing training opportunities for Category “B” nautical cartographers at the UK Hydrographic Office (UKHO) for over 17 years.  The project originally started as the Japan Capacity Building Project (JCBP) in 2009-2013 and the Cartography, Hydrography and Related Training (CHART) Project in 2014-2019, and has now become the Geospatial Marine Analysis and Cartography (GEOMAC) Project since 2020, thanks to the generous support from the Nippon Foundation of Japan. This capacity building project has connected the nautical cartography community, which currently has 112 alumni from 52 countries. The skills and knowledge of this community contribute to solving regional and global challenges beyond the SOLAS obligations.

Empowering Women in Hydrography: A Transformative Three-Year Journey Towards Gender Equality

Like other disciplines within science, technology, engineering, and mathematics (STEM), hydrography exhibits a gender imbalance, particularly in advanced career stages. Currently, just over 10% of the 99 Member States of the International Hydrographic Organization (IHO) have a female National Hydrographer. And while women represent roughly half the population, only 24.8% of them occupy leadership positions with national hydrographic offices. In today’s competitive world, organizations need qualified employees to help them achieve their objectives. By not tapping into half of the available talent pool, they could be missing out.   Acknowledging this disparity, the International Hydrographic Organization (IHO) and the Canadian Hydrographic Service collaboratively initiated a Canadian-funded, groundbreaking three-year project titled "Empowering Women in Hydrography," aimed at fostering gender equality in the field.
