                                        微软亚洲研究院geolife项目研究数据真给力

                                                                  

            晚上花了一点时间，转化了微软亚洲研究院geolife部分数据，确实不错的数据，可以用来做空间数据挖掘等（参考1，参考2），

 

 

            该数据中共有17,621 个轨迹文件，总共大约1200万公里，持续时间为4800多个小时 ，可以做分析研究行为模式等相关研究。 

           直接上图，下图为某用户的部分轨迹显示：
