Abstract: The present disclosure provides system and methods for a sharing geographic location. A local terminal may be configured to display a map interface including a graphic indicator. The graphic indicator may correspond to a remote geographic location of a remote terminal. The local terminal may be further configured to receive a selection signal directed at the graphic indicator to track the remote terminal. In response to the signal, the local terminal may repeatedly receive a geographic location information update corresponding to the remote terminal. The geographic location information update may include an updated geographic location of the remote terminal. In addition, the local terminal may update a travel route indicative of a path between the updated geographic location of the remote terminal and a target geographic location. The terminal may display the travel route on the map interface in real time.
