在本文中,我们建议使用时间线进行二维轨迹比较。在地图上直接渲染的轨迹不能很好地显示时间信息,并且是杂乱和不对齐的。这使得它们难以比较。我们将轨迹转换为时间线,它自然地显示时间,并且更紧凑,更容易对齐。除了简单地显示属性如何随时间变化外,我们还提出了一些新的时间线来显示时空特征。我们提供了一些用例来展示我们的方法的好处。
In this paper, we propose using timelines for 2D trajectory comparison. Trajectories directly rendered on a map do not show temporal information well, and are cluttered and unaligned. This make them difficult to compare. We convert trajectories to timelines, which naturally shows time, and are more compact and easy to align. In addition to simply showing how an attribute varies along the time, we further propose some novel timelines to show spatial-temporal features. We provide some use cases to show the benefit of our method.
