Map keys are an important tool in helping one understand all the information contained in a map. Symbols used on maps are not always consistent or universal, so it is important for any good map to have a key. On a physical map, different symbols help the reader identify the topography of the area. On a city map, there are symbols that indicate the locations of schools and hospitals. Common symbols include colors, pictures and types of lines. A box in one corner of the map usually contains the map key.
