Story Maps combine interactive maps and multimedia content into elegant user experiences. They make it easy for you to harness the power of maps to tell your stories. They've come a long way since first released, and this year's contest winners up the bar in storytelling with maps. At the recent 2016 Esri User Conference, the Storytelling with Maps Contest winners were announced and posted on the Story Maps website. You'll get some great ideas and learn from these excellent examples that use a variety of different story map templates.
