Premise/Promise of Geography, Cartography, GIScience
• Perspectives on:– Conceptualization
• discrete objects vs. continuous fields
– Metaphors • place, region, scale
– Methods• labeling• scale-dependence• visualizing change
– Technology• GIS

Another Interesting Question
What’s “interactivity” anyway?

AAG Abstract Database – Future Work
– Tool development and deployment• AbstractMap System
– AbstractMap Manager
– AbstractMap Viewer
• scalability to large data sets?
– Tool application• time / geographic space / attribute space
– cluster emergence/growth/abandonment
– disciplinary evolution
– institutional evolution
– author trajectories / surfaces
– links between conference site and topics
• integrate across disciplines– map of science
