Personal trajectory dataset

We propose a semantic-based trajectory segmentation simplification method. There are some data to reproduce our research. The trajectory data is the data of two personal GPS trajectories in the city of Nanjing.本研究提出了一种基于语义的轨迹分割简化方法。为便于复现本研究，我们提供了配套的数据集。该轨迹数据集包含两条采集自南京市的个人全球定位系统（Global Positioning System，GPS）轨迹数据。
