Summary:This article presents a visual tool to facilitate the trajectory analysis and the discovery of spatiotemporal patterns in a trajectory data warehouse (TDW). The proposed tool is a spatio-temporal magnifying glass that allows analysts to focus on a specific region, where several trajectories have occurred and to detect, according to some parameters specified by the analyst through a graphical interface, eg the closeness relationship between trajectories or between a trajectory and its surrounding sites. In this article, the authors have proposed and formally define derived closeness relationships between trajectories and between trajectories and sites. An additional contribution was the enrichment of a TDW model, in order to allow the formulation of more expressive queries and to support the visualization aspect of the proposed tool. Although experiments that are more exhaustive are required, their results evidenced some spatio-temporal patterns that demonstrate the convenience and advantages of their tool.
