Nesting grid structure for a geographic referencing system and method of creating and using the same

摘要

A nested grid structure of a geographical referencing system includes one or more regional grids generally centered on one or more respective grid origins, each regional grid including a plurality of cells. One or more local cities are located at least partially within the one or more regional grids. One or more local city grids, each including a plurality of cells, are generally centered on one or more respective local city origins of the one or more local cities. At least some of the plurality of cells of the one or more local city grids directly overlap and coincide with at least some of the plurality of cells of the one or more regional grids to form a nested grid structure.
