Abstract
A system and process is presented that identifies nearby objects and/or points in relation to a base object or point. An object or point is nearby if it resides within a prescribed area around the base point. The identification is based on information accessed from a database of geometric data. The identification of nearby neighbors begins by dividing the geographic system defined by said geometric data into a plurality of zones. The zone in which each object or point resides and the zones intersected by the prescribed area are determined. The nearby objects and/or points of interest are then identified by initially considering only those that are identified as residing in the zones intersected by the prescribed area. The search for nearby neighbors can be further refined by limiting the objects and/or points considered to those with locations within the lateral extent and/or within the height of the prescribed area.
