| Summary / Zusammenfassung | The overall goal of the project is to develop methods for spatio-temporal analysis of groups of moving point objects, e.g. GPS-tracked animals. Whereas recent efforts of dealing with dynamic phenomena within the GIScience community focussed on modeling and representation, this research project concentrates on the analysis task. The analysis is performed on a process level, not on the traditional cartographic approach of comparing snapshots. The research ties up to the time plot method family to analyze mobility pattern of one or two moving point objects (Imfeld 2000). To move on, the time plot family shall be extended to treat bigger groups of moving points and to allow automated rather than human perception based interpretation of time plots. A second research focus is the development of analysis methods to detect patterns of behavior within groups of trackable individuals, basing on the concept of relative movement. Whereas the above methods exclude interrelation to the environment and treat the point groups in pure, featureless space-time, the simultaneous consideration of the environment ends up the research project. |
