Free Extended Time-Geographic Framework Extension for ArcGIS 9.3

The Department of Geography at the University of Tennessee is releasing the free Extended Time-Geographic Framework Tools extension for ArcGIS 9.3. This extension is part of the department's example of the Extended Time-Geographic Framework Tools extensionresearch, Towards a GIS-Based Analytical Time-Geographic Framework for Physical and Virtual Activities, which is funded by a U.S. National Science Foundation (NSF) grant.

With this extension, users can visualize tracking data at the individual level (e.g., GPS or cell phone tracking data; activity/travel diary data; and other survey data of individual locations over time, such as migration history data) in a space-time GIS environment. In addition to the space-time GIS visualization tools included in this extension, the department has developed exploratory spatiotemporal analysis functions based on an extended framework of Hägerstrand's time geography for studying individual activities in both physical and virtual spaces.
