Abstract
Systems and methods for determining whether an object belongs to a target geo-fence are provided. The method may include: obtaining geographic coordinates corresponding to a geographic location of the object; determining information of a grid corresponding to the geographic coordinates; indexing the grid, based on the information of the grid, in a first grid database. The object may not belong to the target geo-fence if the indexed grid is not in the first grid database. The method may further include indexing the grid, based on the information of the grid, in a second grid database if the indexed grid is in the first grid database. The object may belong to the target geo-fence if the indexed grid is not in the second grid database. The method may further include determining whether the object belongs to the target geo-fence based on a relationship of the object and a local geo-fence if the indexed grid is in the second grid database.
