Interested in a career in hydrography? The Royal Institution of Australia (RiAus) has teamed up with the Surveying and Spatial Sciences Institute (SSSI) Hydrography Commission to produce a video showcasing the importance of hydrography as a spatial science discipline and as a rewarding career opportunity.
The video ‘Hydrography as a Career’ is available on YouTube and through the dedicated RiAus website.

The refreshed LINZ website will be here soon.

You’ll still be able to access the same information, but you’ll notice a change in the design and layout of the site.
