Extended Time-Geographic Framework Tools
Extension for ArcGIS 9.3 |
||
|
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 9.3. 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.
