Patent ID: 8065079

Claim:
A method of processing location data at a portable computing device, the method comprising: receiving information associated with a user defined location at the portable computing device, the information including a central point and an entry indication perimeter; receiving at least one entry alert associated with the user defined location at the portable computing device; creating a subpoint via user selection based upon a location of the portable computing device when the portable computing device has not reached the entry indication perimeter associated with the central point of the user defined location, wherein the location associated with the subpoint is different than the location associated with the central point; modifying the entry indication perimeter by the subpoint to generate a modified entry indication perimeter defined by a combination of the entry indication perimeter surrounding the central point and a subpoint entry indication perimeter surrounding the subpoint; monitoring a location of the portable computing device; determining when the portable computing device crosses the modified entry indication perimeter indicating that the portable computing device is proximate to the user defined location; and triggering the at least one entry alert when the portable computing device is determined to be proximate to the user defined location.
