Google Location History (GLH) mobility dataset
收藏资源简介：
This is a GPS dataset acquired from Google. Google tracks the user’s device location through Google Maps, which also works on Android devices, the iPhone, and the web. It’s possible to see the Timeline from the user’s settings in the Google Maps app on Android or directly from the Google Timeline Website. It has detailed information such as when an individual is walking, driving, and flying. Such functionality of tracking can be enabled or disabled on demand by the user directly from the smartphone or via the website. Google has a Take Out service where the users can download all their data or select from the Google products they use the data they want to download. The dataset contains 120,847 instances from a period of 9 months or 253 unique days from February 2019 to October 2019 from a single user. The dataset comprises a pair of (latitude, and longitude), and a timestamp. All the data was delivered in a single CSV file. As the locations of this dataset are well known by the researchers, this dataset will be used as ground truth in many mobility studies.

本数据集为从谷歌（Google）获取的GPS数据集。谷歌可通过谷歌地图（Google Maps）追踪用户设备的位置信息，该服务支持安卓（Android）设备、苹果手机（iPhone）及网页端使用。用户可通过安卓端谷歌地图应用内的个人设置查看位置时间线（Timeline），也可直接通过谷歌时间线官网访问该功能。数据集包含个体步行、驾车及飞行等出行状态的详细记录。该位置追踪功能可由用户直接通过智能手机或网页端按需启用或关闭。谷歌提供数据导出服务（Take Out），用户可借此下载全部个人数据，或从其使用的谷歌产品中选择所需数据进行下载。本数据集源自一位用户2019年2月至2019年10月共9个月、253个独立日期的位置记录，总计120847条数据实例。数据集包含经纬度坐标对与时间戳三类信息，所有数据均存储于单个CSV文件中。由于该数据集的位置信息已被研究人员广泛验证，其将被作为诸多移动性研究中的基准真值（ground truth）使用。若需使用本数据集，请引用如下文献：T.
