The Canadian Hydrographic Service (CHS) is Canada's agency for charting Canadian waters. Canada has the longest coastline of any country in the world, with more than a third of its territory under water.  As a maritime nation, global maritime transport traffic is significant. Hydrography supports safe navigation and shipping through the production of nautical charts and other publications including water levels. With opportunities provided by emerging technologies and the move to e-navigation and autonomous shipping, hydrography is increasingly becoming digital. This presentation will provide an overview of the work underway at CHS, international developments and the future of hydrography as CHS continues the move towards dynamic products and services.
