In order to implement time geography concepts in a space-time (2D space + 1D time) GIS environment, we have developed various data management, analysis, and visualization functions as custom tools in an "Extended Time-Geographic Framework" extension to ESRI ArcGIS software.  We have received many requests of accessing these space-time GIS functions for time geography from people who have seen demonstrations of this time-geographic framework extension over the past years.  We are pleased to release this "Extended Time-Geographic Framework Tools Extension" for ArcGIS 10.0.  Please note that the current release is not compatible with ArcGIS 10.1.

This release includes several functions that generate space-time paths from appropriate input data sets (e.g., GPS tracking data, travel diary data) and facilitate interactive visualization of space-time paths in a space-time GIS environment.

Taking advantages of the existing 3D environment of ArcGIS, we developed custom program code to enable ArcScene (the 3D viewer of ArcGIS) to represent a 3D space-time system of time geography and support the visualization of time geography objects (e.g., space-time paths, space-time prisms) in GIS.  In this extension, the third spatial dimension (z) of ArcScene is used to represent the time dimension (t) in the space-time system of time geography.

Please complete and submit the following form to download the package of "Extended Time-Geographic Framework Tools". After that, you would be able to see two links for the most recent release for ArcGIS 10.0 and the previous release for ArcGIS 9.3, respectively. Select the one that fits your ArcGIS version. The zip file we provide includes an installation file, a user guide, and a data folder. Please read the user guide for instructions.

If you have any questions, please contact the PI and Co-PI of this NSF project listed below.

Sincerely,

Future releases of additional time-geographic functions in a space-time GIS environment will be posted here:
