From Google+ help


  Google+ allows you to share your current location with the people and
  circles you choose across Google products such as Google+ and Google
  Now. Once you've enabled Location Sharing, Google shares your best
  available location.
  
  You can share your pinpoint or city-level location with others, and
  you can do so on a circle-by-circle basis. For example: you can share
  your pinpoint location with family, and your city-level location with
  your co-workers. You can also change who can see your location or
  completely turn off Location Sharing at any time.
  
  To use Location Sharing, you need to:

Turn Location Reporting on from a compatible device [Android] [iOS]. 
Enable Location Sharing and choose who can see your location. 

  
  Turning on Location Reporting alone will not automatically share your
  location; both of these steps need to be taken for Location Sharing to
  work. Manage Location Sharing Turn Location Sharing on or off on
  Android

Open the Google+ application.
From Home, touch Menu &gt; Settings.
Touch the account for which you'd like to turn Location Sharing on or off.
Select Location sharing.
Touch the switch next to Location Sharing to turn it On or Off. Turning off Location Sharing turns off sharing for both your pinpoint

  
  location and city-level location.
      To share your precise location, touch Choose people to share with on the "Pinpoint Location" card.
      To share your current city location, touch Choose people to share with on the "City Location" card.
      Select OK.
  
  If you don't edit your "Pinpoint Location" or "City Location" sharing
  settings, by default, your location is shared with "Only you."
  Where does my location appear?
  
  People you choose to share location information with will be able to
  see your current location on Google products. For example, on your
  Google+ profile, it's displayed below your name and profile photo on
  Desktop, Android, and iOS devices. On Android and iOS, they'll be able
  to see your location on a map in the Locations destination in the
  Google+ app.
