Legend
A legend on a map is a key or explanatory guide that defines symbols, colors, and other elements used on the map to represent various features, ensuring the map can be understood correctly by the user.
In Depth Explanation of Legend
The term 'legend' in cartography has its roots in the Latin word 'legenda' meaning 'things to be read'. The concept has been utilized since the creation of early maps to provide clarity on the depiction of terrain, objects, and data. Early European maps often included legends to explain symbols for cities, rivers, and various geographical features. The practice of including a legend became more standardized during the age of exploration and continues to be a critical component of map design today.
Legends remain indispensable in modern mapping, ensuring users can accurately interpret the data presented. While digital maps may offer interactive legends that only display relevant information when needed, the underlying principle remains unchanged. Whatever the form—whether on a paper map or a digital interface—the legend serves the crucial role of map literacy, aiding in navigation, planning, and understanding complex spatial data.
A Practical Example of the Legend
A practical example of a legend can be seen in the famous 'Mappa Mundi', a medieval European map of the world. Drawing on both real and mythical geography, the legend in the 'Mappa Mundi' is especially crucial as it explains the various religious, historical, and fantastical symbols depicted. By providing this interpretative guide, early mapmakers ensured that viewers could understand the varied and complex information conveyed, thus broadening their comprehension of the world as it was imagined at the time.
