Real Time User Maps

Is it possible to use maps for real time user interface? Similar to how SnapChat maps works, where you can see other users and their locations? Also geolocational notifications…for example everyone in a certain city get notified/advertisement pushed to them?

Not at the moment - there is no way to access users’/devices’ locations, but there is a popular feature request for that here:
