HUN Mine GW and SW mine footprint intersections v01

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement. \n\n\n\nThe dataset contains shapefiles of the the total combined foot prints of all polygons for each of Baseline, CRDP polygons, and the spatial difference between the two (i.e. ACRD). These shapefiles are used in both the surface water and groundwater modelling to define the spatial extent of the mine workings for the three scenarios.\n\n## **Dataset History** \n\nFor each of the surface water and groundwater modelling activities, polygons identified as baseline and ACRD were taken from the source data and merged and dissolved to create respective total baseline and ACRD layers.\n\n\n\nCRDP layers were created by merging the baseline and ACRD layers for SW and GW respectivelty. (CRDP = baseline + ACRD).\n\n\n\nCombined SW+GW layers were created by merging and dissolving the respective layers from the SW and GW sets for baseline, ACRD and CRDP respectively.\n\n\n\nRespective shapefiles have been dissolved to get overall baseline, ACRD and CRDP footprint area without double counting due to overlapping polygons.\n\n\n\nNote: The surface water modelling and groundwater modelling use different sets of mine footprints and even when the same mine has been used in both, the extent may be different for SW vs GW modelling.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (XXXX) HUN Mine GW and SW mine footprint intersections v01.

**摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多份源数据集衍生而来。源数据集的相关信息可参见本元数据声明中的谱系（Lineage）字段；该衍生数据集的制作流程则详见本元数据声明中的历史（History）字段。

本数据集包含三类场景的所有多边形合并覆盖范围（footprint）的形状文件（shapefile），分别为基准场景（Baseline）、CRDP多边形集，以及二者的空间差值集（即ACRD）。上述形状文件将用于地表水与地下水建模，以定义三种场景下的矿井作业空间范围。

**数据集历史**

针对地表水与地下水建模工作，分别从源数据中提取标注为基准场景与ACRD的多边形，经合并与融合得到各自的总基准场景图层与ACRD图层。

CRDP图层则分别通过合并地表水与地下水建模对应的基准场景与ACRD图层创建而成（CRDP = 基准场景 + ACRD）。

通过分别合并并融合地表水与地下水建模集中的基准场景、ACRD与CRDP对应图层，得到合并后的地表水+地下水图层。

对各图层进行融合处理，以消除重叠多边形导致的重复计数，最终得到各场景的总覆盖范围区域。

注：地表水建模与地下水建模所使用的矿井覆盖范围数据集存在差异，即便同一矿井同时用于两类建模，其覆盖范围也可能因建模需求不同而有所区别。
