A map is a graphical visualisation of the world around us and is made up using a variety of symbols to help us represent that geography.
Maps use symbols to label real-life features and make the maps clearer. With so many features on a map, there would not be enough space to label everything with text.
Symbols can be small pictures, letters, lines or coloured areas to show features like campsites, pubs or bus stations. If you look closely at a map, you will see that it is covered in symbols.
