Abstract: Identifying the geographic region of a geographic area which contains a geographic zone. To identify the geographic region which contains a geographic zone, one of the plurality of geographic regions in a geographic area is selected as a selected region. A determination is made as to whether the geographic zone is located within the selected region by determining whether the zone boundary points of the geographic zone are located within the selected region. If a predetermined percentage of the zone boundary points of the geographic zone are located within the selected region, then the geographic zone is located within the selected region and the geographic region is identified. To determine whether a zone boundary point is located within the selected region, a determination is made as to whether a line of predetermined slope drawn through the zone boundary point intersects the region boundary of the selected region.

Abstract: A system and method for identifying the geographic region of a geographic area which contains a geographic point associated with a location. A description of a location such as an address, a nearby intersection, or a nearby landmark, is used to determine geographic coordinates for a geographic point associated with the location. To identify the geographic region which contains the geographic point, one of the plurality of geographic regions in a geographic area is selected as a selected region and a determination is made as to whether the geographic point is located within the selected region. If the geographic point is located within the selected region, then the geographic region is identified. Different preferred methods correspond to different methods for making a determination as to whether the geographic point is located within the selected region.

Abstract: A system and method for identifying a geographic point within a geographic section of a geographic area. A geographic area containing a plurality of geographic points is divided into a plurality of non-overlapping geographic regions. A geographic section of the geographic area is selected. A geographic region is selected as a selected geographic region and a region determination is made as to whether the geographic section overlaps the selected geographic region. If the geographic section overlaps the selected geographic region, then a geographic point located within the selected geographic region is selected as a selected geographic point. A point determination is made as to whether the selected geographic point is located within the geographic section. If the selected geographic point is located within the geographic section, then the selected geographic point is identified.
