QLD Cadastral data for the Galilee subregion - 12/01/2014

## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\n\n\nThe cadastral dataset is the spatial representation of property boundaries and descriptions in the following QLD local government areas: \n\nBarcaldine\n\nBlackall Tambo\n\nBulloo\n\nCentral Highlands\n\nCharters Towers\n\nFlinders\n\nIsaac\n\nLongreach\n\nMaranoa\n\nMurweh\n\nParoo\n\nQuilpie\n\nRichmond\n\nWinton\n\n\n\nIt is a fundamental reference layer for spatial information systems in Queensland. This is a complete extract from the digital cadastral database (DCDB). A lite version of the DCDB is available from the Queensland Government Information Service website. Attributes are described in the "QIF file specifications" at http://www.nrm.qld.gov.au/property/mapping/dcdata/index.html\\#data_attributes .\n\n## **Dataset History** \n\nLineage statement:\n\nThe DCDB was captured by digitising the best available cadastral mapping at a variety of scales and map accuracies. These mapping scales ranged from Standard 1:2500 to 1:250000, Provisional 1:2500 to 1:253400 and mapping such as Parish, Locality, Environ and Town maps. At the initial capture, existing control identified from the Survey Control Database, standard cadastral and topographic mapping, photogrammetric and orthophoto compilations and this control was used as part of the digitising process. Additional control was requested if necessary. The DCDB is continuously updated by inputting metes and bounds descriptions from registered plans of subdivision and from any attribute updates from government gazettes and other administrative notifications. The DCDB is being upgraded for an improved positional accuracy, this is an ongoing process. In October 2000, the datum of DCDB was converted from AGD84 values. A distortion model based on a Queensland grid was used in the transformation process for the conversion of the DCDB co-ordinate values from AGD84 to GDA94. The distortion grid used is QLD_0900.gsb. The DCDB includes polygons and feature names for parts of the sea adjoining the coastline of Queensland. The spatial representation of any part of the sea has been delineated in the DCDB by the construction of polygons. The feature names assigned to those polygons have been obtained from a variety of sources, Topographic Maps, Navigation Charts, local usage, etc. Indeterminable Extent, the delineation in the DCDB of the extent of any part of the sea by the creation of construction lines for each polygon is to permit the inclusion of the feature name only. The construction lines are not warranted to be the actual boundaries of any water feature or to be accurate or complete.\n\nProcess step:\n\nThe DCDB data, in DCDB transfer format (IFO), is FTP'd to the Spatial Information Resource server every fortnight where it is transformed into the Spatial Information Resource (SIR) ArcSDE Geodatabase.Note: the MapInfo dataset was generated/transformed/derived from the ARCSDE dataset.\n\n\n\nSee also, Metadata HTML for each shapefile.\n\n## **Dataset Citation** \n\nQueensland Department of Natural Resources and Mines (2014) QLD Cadastral data for the Galilee subregion - 12/01/2014.

**数据集历史**

谱系声明：

DCDB通过数字化多种比例尺与地图精度等级的最优现有地籍测绘成果构建。测绘比例尺涵盖标准比例尺1:2500至1:250000、临时比例尺1:2500至1:253400，以及教区地图、区域地图、环境地图与城镇地图等类型。

在初始构建阶段，从测量控制数据库、标准地籍与地形测绘、摄影测量及正射影像汇编中提取的现有控制参数被用于数字化流程；必要时还会补充额外控制参数。

DCDB会持续更新：输入已注册的细分规划中的界址描述，以及政府公报与其他行政通知中的属性更新内容。

为提升位置精度，DCDB正处于持续升级的过程中。

2000年10月，DCDB的基准面从AGD84转换为GDA94。转换过程中采用基于昆士兰网格的畸变模型，使用的畸变网格文件为QLD_0900.gsb。

DCDB包含昆士兰州沿海毗邻海域的多边形要素与名称。DCDB通过构建多边形来划定沿海海域的空间范围，多边形的要素名称来源于地形地图、航海图、当地通用叫法等多种渠道。需说明的是，DCDB中通过构建多边形构造线划定的海域范围仅用于标注要素名称，其构造线不保证为任何水体的实际边界，也不保证准确或完整。

流程步骤：

采用DCDB传输格式（IFO）的DCDB数据每两周通过文件传输协议（File Transfer Protocol, FTP）上传至空间信息资源服务器，并转换为空间信息资源（Spatial Information Resource, SIR）ArcSDE地理数据库。注：MapInfo数据集由ArcSDE数据集生成、转换或衍生而来。
