Abstract:
1. A method for determining an identity of a named territory enclosing a physical target location specified by a target longitude and a target latitude, comprising: identifying a number of rectangular-shaped terrestrial areas that each enclose both the target longitude and the target latitude, wherein each of the number of identified rectangular-shaped terrestrial areas respectively encloses a number of polygonal-shaped named territories, and wherein each polygonal-shaped named territory is defined by a respective circumscribing set of contiguously positioned vectors; evaluating the circumscribing sets of contiguously positioned vectors of the number of polygonal-shaped named territories to determine if a given polygonal-shaped named territory includes both the target longitude and the target latitude; and conveying an identity of the given polygonal-shaped named territory as the named territory enclosing the physical target location when both the target longitude and the target latitude are found to reside within the given polygonal-shaped named territory.
