Google Location History (GLH) mobility dataset

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.

本数据集为谷歌（Google）获取的GPS（全球定位系统）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，该服务支持安卓设备、苹果手机及网页端使用。用户可通过安卓端谷歌地图应用中的用户设置页面，或直接访问谷歌时间线官网（Google Timeline Website）查看其位置时间线。
该数据集包含丰富的细节信息，例如用户步行、驾车及搭乘飞行器的相关记录。用户可直接通过智能手机或网页端按需启用或关闭该位置追踪功能。
谷歌提供了数据导出（Take Out）服务，用户可借此下载其全部数据，或从使用的谷歌产品中按需选择所需下载的数据。
本数据集源自2019年2月至2019年10月共9个月、253个独立日期的单用户数据，总计包含120,847条数据实例。每条数据实例包含经纬度坐标（latitude, longitude）及时间戳（timestamp），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为研究人员所熟知，其将在诸多人类移动性研究中作为基准真值（ground truth）使用。
