For more information about this layer please see the GIS Data Catalog. Polygons defining the directional prefix and suffix combinations according to the county address grid. Some cities have street names and directional components that differ from the county standard. An attempt has been made to include these by reviewing available materials.如需了解该图层的更多信息，请参阅地理信息系统（GIS）数据目录。本数据集包含依据县级地址网格定义方位前缀与后缀组合的多边形要素。部分城市的街道名称及方位组成部分与所在县级标准有所不同，本次已通过梳理现有资料，尝试将此类情况纳入数据集范围。
