TL;DR: This article summarizes the results of the workshop on Visualization, Analytics & Spatial Decision Support, which took place at the GIScience conference in September 2006, and suggests a new research direction ‘Geovisual Analytics for Spatial decision Support’, which emphasizes the importance of visualization and interactive visual interfaces and the link with the emerging research discipline of Visual Analytics.

TL;DR: This work focuses on leveraging explicit and implicit geographic information for tweets, on developing place-time-theme indexing schemes that support overview+detail methods and that scale analytical capabilities to relatively large tweet volumes, and on providing visual interface methods to enable understanding of place, time, and theme components of evolving situations.
