spots的Python项目详细描述
斑点
谷歌位置历史实用程序
安装
$ pip install spots
用法
加载位置历史json作为pandas数据帧
fromspotsimportLocationHistorylocdf=LocationHistory.from_json("your-location-history-file.json")locdf.head()# accuracy activity lat lon timestamp# confidence timestamp type #0 24 100 2014-01-05 09:47:07.808 UNKNOWN -23.340981 -46.579202 2014-01-05 09:47:07.808#1 24 100 2014-01-05 09:47:54.558 TILTING -23.123471 -46.631244 2014-01-05 09:48:21.891#2 24 100 2014-01-05 09:49:21.461 UNKNOWN -23.456211 -46.640234 2014-01-05 09:49:21.461#3 24 100 2014-01-05 09:50:21.470 UNKNOWN -23.464231 -46.604355 2014-01-05 09:50:21.470#4 25 100 2014-01-05 09:51:21.623 UNKNOWN -23.490080 -46.709021 2014-01-05 09:51:21.623
计算轨迹的停留点
StayPointDetection类实现了sklearn群集使用的相同接口
算法。
fromspotsimportStayPointDetectionimportnumpyasnpspd=StayPointDetection(distance=0.05,time=np.timedelta(15,'m'))staypoints=spd.fit_predict(X=locdf[['lat','lon']].values,timestamp=locdf.timestamp)locdf.loc[:,"staypoint_id"]=staypoints
