Spatial location systems can be based on multi-resolution grids such as mixed aperture combinations of hexagonal cells. A particular finest resolution can be selected based on a suitable combination of intermediate grid apertures such as arbitrary combinations of aperture 3, aperture 4, and aperture 7 hexagons. Location identifiers can be uniquely assigned by generating child cells from a parent cell so that the generated child cells do not overlap child cells of other parent cells. One or more child blocks can be used at any resolution to avoid such overlap. For aperture three and aperture four hexagonal cells, blocks of four and three child cells, respectively, can be used to provide unique location identifiers. |
