摘要
Object identification is described. A processor identifies a first cell of a rectangular grid overlapped over a map of a certain geographic area. The first cell corresponds to a given geographic location. The processor identifies a second cell of the grid, the second cell having a center located within a certain distance of a center of the first cell. The processor identifies one or more objects associated with the second cell by using geographic coordinates of the center of the second cell as a lookup key to identify one or more entries of a data structure that stores object information.
