HUN GW modelling total mine footprint 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 the groundwater modelling to define the spatial extent of the mine workings for the three scenarios.\n\n## **Dataset History** \n\nPolygons for Baseline mines, and CRDP mines were respectively dissolved to create singe total Baseline footprint area and CRDP footprint area. The Baseline total footprint was removed (ERASE command) from the CRDP total footprint to create a ACRD total footprint.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) HUN GW modelling total mine footprint v01.

## **摘要**

本数据集由生物区域评估项目（Bioregional Assessment Programme）基于多份源数据集衍生而来。源数据集的相关信息已在本元数据声明的“谱系（Lineage）”字段中列明，本衍生数据集的生成流程则在本元数据声明的“历史（History）”字段中予以说明。

本数据集包含三类空间矢量格式文件（shapefile）：分别为基准场景（Baseline）、CRDP场景下所有多边形的总合并矿山占地范围，以及二者的空间差值（即ACRD）。上述shapefile将在地下水模拟中用于界定三类场景下矿山开采作业的空间范围。

## **数据集历史**

基准矿山场景与CRDP矿山场景的多边形分别经融合（Dissolve）处理，得到基准场景总占地范围与CRDP场景总占地范围。随后通过擦除命令（ERASE command）将基准场景总占地范围从CRDP场景总占地范围中移除，从而生成ACRD总占地范围。
