Multiscale Visualization of Trajectory Data
Sheng Liang, Qing Xu, Yuejun Guo, Fan Yang · 2015
This paper proposes a novel three-dimensional (3D) visualization tool for the trajectory analysis, helping users understand the trajectory data from different perspectives. The details of a single and a set trajectories are well covered in multiscale views by the four main linked windows, namely Traj View, Color Bar, Multi Property and Track Map. We take advantage of and further improve the color bar and the parallel coordinates to effectively present the important attributes of trajectories and also the relationship between different attributes. In addition, the interactive actions, such as keyboard and mouse operations, provide a rich and wonderful user experience.
