Maps are valuable because they provide a large amount of detail in a small amount of space, and because of their capacity for telling a story. Telling stories through maps began with describing explored lands in great detail against terra incognita. Today, geographic tools, data, and multimedia on the web expand the ability to communicate stories and inform through maps to a broad audience such as journalists, decision makers and educators. Any person with a smartphone or computer can tell a story, using statics maps, or interactive web maps with text, video, audio, sketches, and photographs. Besides the technical skills to clearly communicate with a map (palette of colours, amount of information displayed…), other factors such as narrative processes, the storyboard, place, time, and characters play a crucial role. To be informative, it is important that the correct data is displayed, combining different sources of information combined to create an appealing and accurate map.
