In one embodiment, a method includes accessing a location history of a user of a social-networking system. The social-networking system includes a social graph that includes multiple nodes and edges connecting the nodes. At least node corresponds to the user. The method includes accessing a data set from a third-party source independent of the social-networking system. The data set references one or more locations. The method includes comparing the location history of the user with the locations referenced by the data set to determine an overlap between the location history and the data set and determining based on the comparison one or more labels to assign to the user or to one or more locations where the location history and the data set overlap.

Analyzing geo-spatial data in layers

A method includes determining an operating condition associated with a mobile device based on contextual information associated with one or more of usage information of the mobile device, user activity of a user of the mobile device, or location information. If the operating condition satisfies a threshold power-consumption condition, the method further includes adjusting a frequency of collecting location information of the mobile device and collecting information on a plurality of locations associated with the mobile device for a particular time period based on the adjusted frequency of collecting the location information. The method further includes adjusting a frequency of uploading collected location information to a server associated with a social-networking system and sending the information on the plurality of locations for a particular time period to the social-networking system based on the adjusted frequency of uploading collected location information for building a location timeline for the mobile device.
