what is the importance of the legend of a map?
Answers
A map key or legend is included with a map to unlock it. It gives you the information needed for the map to make sense. Maps often use symbols or colors to represent things, and the map key explains what they mean. Map keys are often boxes in the corner of the map, and the information they give you is essential to understanding the map. Symbols in the key might be pictures or icons that represent different things on the map. Sometimes the map might by colored or shaded, and the key explains what the colors and shades mean. The picture here shows an example of a map key for a typical road map.

What is the importance of a legend on a map?
I just want to add to his answer because maps without legends are a pet hate of mine. I see too many of them. Why bother? Nobody can understand what a map without a legend about! But yet so often an absolutely beautiful piece of graphic art gets hailed as being a wonderful map. In the examples I’m talking about the map creator typically creates their thematic map with well coordinated colors, yet there is often no clue as to what the map is about…often not even a caption!
