GeoLife
收藏资源简介:
This GPS trajectory dataset was collected in (Microsoft Research Asia) Geolife project by 178 users in a period of over four years (from April 2007 to October 2011). A GPS trajectory of this dataset is represented by a sequence of time-stamped points, each of which contains the information of latitude, longitude and altitude. This dataset contains 17,621 trajectories with a total distance of 1,251,654 kilometers and a total duration of 48,203 hours. These trajectories were recorded by different GPS loggers and GPS-phones, and have a variety of sampling rates. 91 percent of the trajectories are logged in a dense representation, e.g. every 1~5 seconds or every 5~10 meters per point. This dataset recoded a broad range of users??? outdoor movements, including not only life routines like go home and go to work but also some entertainments and sports activities, such as shopping, sightseeing, dining, hiking, and cycling. This trajectory dataset can be used in many research fields, such as mobility pattern mining, user activity recognition, location-based social networks, location privacy, and location recommendation.
本GPS轨迹数据集由微软亚洲研究院(Microsoft Research Asia)GeoLife项目采集,共有178名用户参与,采集周期跨越四年有余(2007年4月至2011年10月)。该数据集的每条GPS轨迹均由一系列带时间戳的点位构成,每个点位均包含纬度、经度与海拔信息。本数据集共计收录17621条轨迹,总行驶里程达1251654公里,总时长为48203小时。这些轨迹由不同型号的GPS记录仪与GPS手机采集,采样率存在差异。其中91%的轨迹采用高密度采样记录方式,例如每1~5秒或每5~10米采集一个点位。本数据集记录了覆盖广泛用户群体的户外出行活动,不仅涵盖通勤归家、日常上班等生活轨迹,还包含购物、观光、就餐、徒步与骑行等娱乐及体育活动。该轨迹数据集可应用于诸多研究领域,例如出行模式挖掘、用户行为识别、基于位置的社交网络、位置隐私保护与位置推荐等。
