Broadcasting Licence Areas

The _Broadcasting Services Act 1992_ mandates that Commercial and Community broadcasting services are licensed to serve specific geographic areas. \r\nThese geographic areas are referred to as **Licence Areas**, and are determined by the Australian Communications and Media Authority (ACMA) in Licence Area Plans (LAPs). \r\nThe ACMA defines Licence Areas in terms of areas defined by the\r\n[Australian Bureau of Statistics](http://www.abs.gov.au/) (ABS) for the\r\npurposes of the Australian Census. The smallest area unit currently defined\r\nby the ABS is the Collection District (CD).\r\n\r\nThis dataset comprises the collection of current broadcast Licence Areas, and\r\nis made available in five forms:\r\n\r\n * the list of Australian Bureau of Statistics CD numbers making up the Licence Area definition, distributed in a comma separated value (CSV) format text file;\r\n * a translation of the ABS CD numbers into the names of the Local Government Areas (LGAs) and Statistical Division (SDs) within the area boundary, known as the Licence Area Description, rendered as an HTML page;\r\n * a geographic map displaying the Licence Area, distributed as a Portable Document Format (PDF) file;\r\n * a spatial dataset for use in GIS software, distributed as a ZIP archive containing ESRI Shapefile Format data files; and\r\n * a Google Earth Placemark (.KMZ) file viewable in the Google Earth application and other software that can display Placemark data.\r\n\r\n

《1992年广播服务法》（Broadcasting Services Act 1992）明确要求，商业广播服务与社区广播服务须申领专属牌照，且需面向特定地理区域提供服务。此类地理区域被称为**许可区域（Licence Areas）**，由澳大利亚通信和媒体管理局（Australian Communications and Media Authority，ACMA）通过《许可区域规划》（Licence Area Plans，LAPs）划定。
澳大利亚通信和媒体管理局依据澳大利亚统计局（Australian Bureau of Statistics，ABS，[官方网站](http://www.abs.gov.au/)）为澳大利亚人口普查设定的区域范围来定义许可区域。目前澳大利亚统计局划定的最小区域单元为普查集区（Collection District，CD）。

本数据集收录当前有效的广播许可区域，共提供五种分发格式：

* 以逗号分隔值（CSV）格式存储的文本文件，内含构成许可区域定义的澳大利亚统计局普查集区编号列表；
* 转换为地方政府区域（Local Government Areas，LGAs）及对应区域内统计分区（Statistical Division，SDs）名称的许可区域说明文档，以HTML页面形式呈现；
* 展示许可区域边界的地理地图，以可移植文档格式（PDF）文件分发；
* 适用于地理信息系统（GIS）软件的空间数据集，以ZIP压缩包形式分发，内含ESRI形状文件格式（ESRI Shapefile Format）的数据文件；
* 可在Google Earth应用及其他支持地标数据的软件中查看的Google Earth地标（.KMZ）文件。
