• Enable location services on your phone (this will tag your pictures with the gps location in which they have been taken)
On an iPhone go to Settings: Privacy: Location Services: Camera and check to allow location access “While using the app.” Follow this guide.

• Claim a location on the map at Pick the Mexico City project and click on a green icon in the location you want to take the picture from.
