I work in an application that uses the Geolocation API of Google Maps to obtain the location of devices. In the application you can create a geo fence so that it will notify you if the device has left its assigned area. The problem is that currently the application sends you the notification if the location of the device is outside the area so the circle of precision is touching the area, would like to condition that if the circle of precision is touching the geo fence does not issue the notification. But I do not know how to measure if the precision circle is inside the geo fence.
