Abstract

Analyzing observations over time and geography is a common task, but typically requires multiple, separate tools. The objective of our research has been to develop a method to visualize, and work with, the spatial inter-connectedness of information over time and geography within a single, highly interactive three-dimensional (3-D) view. A novel visualization technique for displaying and tracking events, objects and activities within a combined temporal and geospatial display has been developed. This technique has been implemented as a demonstrable prototype called GeoTime in order to determine potential utility. Capabilities include descriptive events and relationships, association analysis, event aggregation methods and geo-located linked charting. Initial evaluations have been with military users. However, we believe the concept is applicable to a variety of government and business analysis tasks.
