Abstract
The objective of interactive geographic maps is to provide geographic information to a large audience in a captivating and intuitive way. Storytelling helps to create exciting experiences and to explain complex or otherwise hidden relationships of geospatial data. Furthermore, interactive 3D applications offer a wide range of attractive elements for advanced visual story creation and offer the possibility to convey the same story in many different ways. In this paper, we discuss and analyze storytelling techniques in 3D geographic visualizations so that authors and developers working with geospatial data can use these techniques to conceptualize their visualization and interaction design. Finally, we outline two examples which apply the given concepts.
Highlights
Interactive 3D geographic visualization systems such as Google Earth provide geographic information to users in an effective and attractive way
Users often do not manage to identify relevant but possibly hidden places and spatial patterns in a map because they are overwhelmed by the sheer amount of data, map elements, and functions
Interactive storytelling has been studied intensively by several research communities and is too broad to be covered in its entirety
Summary
Interactive 3D geographic visualization systems such as Google Earth provide geographic information to users in an effective and attractive way The purpose of such systems lies in the interactive visualization of geospatial data from an existing data source. Users often do not manage to identify relevant but possibly hidden places and spatial patterns in a map because they are overwhelmed by the sheer amount of data, map elements, and functions These systems are not designed to entice users to explore the geographic space and the thematic data by curiosity. Our main question for interactive storytelling is how authors can design effective stories for geographic visualization systems that motivate users to explore interactive maps. We list and evaluate scene components to communicate more complex or hidden facts
