Lake Eyre Basin Surface water Potential Assessment Extents v01

## **Abstract** \n\nThis dataset was derived by the Bioregional Assessment Programme. The parent datasets are identified in the Lineage field in this metadata statement. The process undertaken to produce this derived dataset are described in the History field in this metadata statement. \n\n\n\nThis dataset shows the surface water potential assessment extent (PAE) (version 1) for subregions within the Lake Eyre Basin Bioregional Assessment area. These first pass PAEs include the whole subregion as well as selected surface water features outside the subregion which are deemed to flow out of coal and coal seem gas tenement areas.\n\n\n\nThese PAEs do not include springs, bores or groundwater features.\n\n## **Purpose** \n\nThe role of the PAE is to optimise research agency effort by focussing on those locations where a material causal link may occur between coal resource development and impacts on water dependent assets. The lists of assets collated by the Program are filtered for "proximity" such that only those assets that intersect with the PAE are considered further in the assessment process. Changes to the PAE such as through the identification of a different development pathway or an improved hydrological understanding may require the proximity of assets to be considered again. Should the assessment process identify a material connection between a water dependent asset outside the PAE and coal resource development impacts, the PAE would need to be amended.\n\n## **Dataset History** \n\nThe following steps were followed to create each subregion's surface water PAE.\n\n\n\n1. Surface water features from Geoscience Australia's 250K stream and lake datasets (GEODATA TOPO 250K Series 3, GUID: a0650f18-518a-4b99-a553-44f82f28bb5f) were opened in ArcMap.\n\n2. Surface water features were selected which flow downstream from existing exploration or production coal and/or coal seam gas tenements (including those tenements under application at the time of creation) (sourced from multiple Queensland and South Australia tenement datasets, see Lineage).\n\n3. Line features were buffered by 1km to create polygons.\n\n4. All surface water polygons were merged with the subregion boundary polygon (Bioregional Assessment areas v02, GUID: e414b1b3-c42e-42e9-9cc4-2093054aa35f)\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (XXXX) Lake Eyre Basin Surface water Potential Assessment Extents v01.

**摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）衍生生成。其源数据集已在本元数据声明的Lineage字段中列明，衍生该数据集的具体流程则详见本元数据声明的History字段。

本数据集展示了艾尔湖盆地生物区域评估区域内各子区域的地表水潜在评估范围（Potential Assessment Extent，PAE）第一版。该首轮评估范围涵盖整个子区域，以及经认定源自煤炭及煤层气矿业权区域、且流出子区域的部分地表水要素。

本潜在评估范围未包含泉眼、钻井或地下水要素。

**数据集用途**

本潜在评估范围的作用在于优化科研机构的工作重心，将研究聚焦于煤炭资源开发与水依赖性资产受损之间可能存在实质性因果关联的区域。本计划整理的资产清单会基于“邻近性”进行筛选，仅将与潜在评估范围相交的资产纳入后续评估流程。若因识别出新的开发路径或水文认知升级而对潜在评估范围进行调整，则需重新考量资产的邻近性。若评估过程发现潜在评估范围外的水依赖性资产与煤炭资源开发影响之间存在实质性关联，则需对潜在评估范围进行修正。

**数据集生成历史**

各子区域地表水潜在评估范围的生成流程如下：

1. 在ArcMap中加载澳大利亚地质调查局（Geoscience Australia）25万比例尺水系与湖泊数据集（GEODATA TOPO 250K Series 3，全球唯一标识符（GUID）：a0650f18-518a-4b99-a553-44f82f28bb5f）。
2. 选取源自现有煤炭及煤层气探矿权、采矿权权证（包括数据集生成时处于申请阶段的权证）下游的地表水要素（数据源自昆士兰州与南澳大利亚州多套矿业权数据集，详见Lineage字段）。
3. 对线状要素进行1公里缓冲区分析，生成面状要素。
4. 将所有地表水面对要素与子区域边界面要素（生物区域评估区域v02，全球唯一标识符（GUID）：e414b1b3-c42e-42e9-9cc4-2093054aa35f）进行合并。
