Component 1: Current and Future Methods for Representing and Interacting with Qualitative Geographic Information
Abstract
Geographically-grounded text information is an increasingly common data type that has the potential to increase our ability to understand place-based activities and processes dramatically if methods can be developed to extract, process, and represent that information as well as to connect the information with more traditional geographic data organized within GIS and related technologies. A variety of approaches exist for visual exploration and analysis of text media, and this report highlights and categorizes known approaches towards handling text information in information visualization and geographic information technologies. In addition, we describe the most common techniques for interacting with textual data and its derivatives in geographic and non-geographic visualization systems. Finally, we propose several graphical methods for using text itself to represent different dimensions of geographic information. These methods, as well as others we review from previous work, help elaborate a path forward for future geographic information technologies that can more effectively leverage geographically-grounded text.
