Surrounding Municipal Boundary

This layer was developed by the Research & Analytics Division of the Atlanta Regional Commission and contains city and municipal boundaries for the 20 county Atlanta region and rest of state. City boundaries within the 20 county region are derived from boundaries provided by local governments and updated on a continual basis when new data are received but do not represent the most up to date in all cases. Rest of state boundaries are derived from Census boundary data and updated much less frequently. Please note that cities with multiple polygons have been merged into a single multi-part polygon to facilitate labeling and querying. Attributes: Municipality_Name Name of city or municipality Acres Float value of Acres Sq_Miles Float value of Square Miles Source: U.S. Census Bureau, GA Dept. of Community Affairs, Local Governments, Atlanta Regional Commission For additional information, please contact respective local governments and visit Census Bureau place data website.本图层由亚特兰大区域委员会（Atlanta Regional Commission）研究与分析部开发，涵盖20县亚特兰大区域及该州其余区域的城市与市政边界。20县亚特兰大区域内的城市边界源自地方政府提供的边界数据，会在收到新数据时持续更新，但并非在所有场景下均为最新版本。州内其余区域的边界则取自美国人口普查局（U.S. Census Bureau）的边界数据，更新频率相对较低。请注意，拥有多个多边形的城市已被合并为单个多部分多边形，以方便标注与查询操作。属性信息如下：1. Municipality_Name（Municipality_Name）：城市或市政单位的名称；2. Acres：以英亩为单位的浮点型数值；3. Sq_Miles：以平方英里为单位的浮点型数值。数据来源：美国人口普查局（U.S. Census Bureau）、佐治亚州社区事务部（GA Dept. of Community Affairs）、地方政府、亚特兰大区域委员会。如需获取更多相关信息，请联系对应地方政府，或访问美国人口普查局辖区数据官方网站。
