Getting coordinates for frequent locations?
There is nothing directly on the iOS device to provide the coordinates. Through the iOS developer sdk you can access the CLVisit class which has the following properties:

coordinate- which will give you the geographic coordinates
horizontalAccuracy- gives the horizontal accuracy of the above coordinates
arrivalDate- date arrived to location
departureDate- date departed location

There is also a CLFloor class which has the following property

level- which will give you a value for the floor. 0 bring ground floor, 2 being 2 floors above the ground floor, etc.
