GIS Methods in Time-Geographic Research:
Geocomputation and Geovisualization of
Human Activity Patterns

Mei-Po Kwan

Abstract: In the past 40 years or so, human activities and movements in space-time have attracted considerable research interest in geography. One of the earliest analytical perspectives for the analysis of human activity patterns and movements in space-time is time geography. Despite the usefulness of time geography in many areas of geographical research, there are very few studies that actually implemented its constructs as analytical methods up to the mid-1990s. With increasing availability of georeferenced individual-level data and improvement in the geocomputational capabilities of Geographical Information Systems (GIS), it is now more feasible than ever before to operationalize and implement time-geographic constructs. This paper discusses recent applications of GIS-based geocomputation and three-dimensional (3D) geovisualization methods in time-geographic research. Usefulness of these methods is illustrated through examples drawn from the authorís recent studies. The paper attempts to show that GIS provides an effective environment for implementing time-geographic constructs and for the future development of operational methods in time-geographic research.

Key Words: time geography, space-time paths, GIS, geocomputation, geovisualization
