摘要
从网格的定义出发,论述了规则网格与不规则网格的特点,描述了等级不规则网格的组成,指出地籍是城市最小不规则空间网格单元,利用地籍可以组合成其他管理分区(网格),使城市空间信息的纵向综合与横向共享得以实现,最后探讨了基于等级不规则网格的地理编码标准。
Grid and geocodes are dual. Grid is the dimension that geocodes represent, and geocodes are geographic identifiers of grid cell. Starting off with the definition of the grid, This paper discussed the characteristics of regulate and irregular grid, focused on composition of multi-scale irregular grid, and pointed out that cadastre is a basic cell of urban flat surface and can make up other professional grid so that spatial information can be synthesized and shared. At length, this paper analysed and probed into the standard of geocodes based on irregular grids.
