Welcome to the Guess-the-icons survey!

This survey is a step in developing the IMO guideline for the standardisation of functions and display of navigation equipment (S-mode), aiming to standardise the displays of marine navigation systems.

In the following page, we will show you a couple of icons used for the interface of marine navigation systems. Let's see if you can guess their meanings.
It's fun and only takes five minutes to complete.
