StoryMap, by Knight Lab, can be used to tell a highlight of a particular image or historical map (its tagline is “maps that tell stories”). Users can guide viewers through a series of zoomed-in highlights to a particular image or map, highlight areas of interest in the image. Each item that’s designated can feature text, images, audio, or video.
One example is Arya’s Journey, for you Game of Thrones fans. You can view Arya’s journey from the book series on a historical map.
