Android :: GPS Queueing In LocationListener

The application under development was to distinguish between the current location of the android phone based upon GPS signal when it was available. When it is not available, alternate methods are being used to distinguish the user's location. The application uses a private locationlistener class that implements the LocationListener class. The code within the onLocationChanged( ) method to be overridden will draw the location on the google map as a dot as they are received.

I have noticed however that something is amiss. If you start outside the building, it will estimate your position with several dots around your current location. When you walk through a building where you don't get GPS, the dots are not drawn as expected, but as soon as you step outside again on the other side of the building it rapidly draws dots far away from (but leading up to) your location, until it gets to your actual current location. I don't understand how these other values are retrieved and why they seem to poke their ugly heads in, once the user steps back outside............
