“A legend is used to decode the symbology applied to layers. The legend details the colour schema , symbolisations and how data is categorised”
Maps are used as a visual tool to interpret data and show the spatial relationship between data. One of the most important elements of a map is the legend as it allows people to interpret the symbology and decode the meaning of the colour applied to vector and raster layers. In this module, we look at how to produce a map with a legend that is easy to interpret.

A map legend or key is a visual explanation of the symbols used on the map. It typically includes a sample of each symbol (point, line, or area), and a short description of what the symbol means. Because map symbols meanings vary from region to region, a clear and concise legend is critical for conveying the distinctive characteristics of the map. The legend is related to the information on the map it is connected to. Creating a well laid out legend will enhance the overall shape of the maps visual appearance. In this example, we explored how legends can be added to QGIS and modified in map composer.
