                                      再发 微软亚洲研究院出租车轨迹数据超级给力

 

                                                                  

            晚上花了一点时间，转化了微软亚洲研究院出租车轨迹数据部分数据，数据相当好，可以用来做空间数据挖掘等（参考1，参考2，参考3）

 

            该数据中共有10357 个轨迹文件，总共大约900万公里，大约有1500万轨迹点，可以做分析研究行为模式等相关研究。 

            直接上图，下图为部分轨迹显示：
