This technique is used to visualize and explore trajectories of moving objects. However, it may be ineffective when the number of different trajectories is large and/or the time span of the data is long. We overcome the limitations in two complementary ways: first, clustering of trajectories by spatial similarity, and, second, transformation of the temporal references within the trajectories to facilitatecomparisons within and between clusters. We demonstrate the work of the approach on a real data set about individual movement over one year.enspace-time cubegeographic spacetrajectory005006629conference paper
