HUN SW 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 surface water modelling to define the spatial extent of the mine workings for the three scenarios.\n\n## **Purpose** \n\nUsed only for report map display and area calculation purposes\n\n## **Dataset History** \n\nPolygons from the source dataset were selected as follows:\n\n\n\nfor the total surface water modelling baseline footprint polygons were selected where SW_BL - 'yes'.\n\n\n\nfor the CRDP footprint polygons were selected where any of SW_BL, SW_CRDP or SW_ACRD = "yes"\n\n\n\nThe Baseline total footprint was removed (ERASE command) from the CRDP total footprint to create a ACRD total footprint.\n\n\n\nRespective selections were dissolved to obtain overall total footprints.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) HUN SW modelling total mine footprint v01.

CRDP总覆盖范围多边形：筛选条件为SW_BL、SW_CRDP或SW_ACRD任一字段值为“yes”； 通过ERASE命令将基线总覆盖范围从CRDP总覆盖范围中移除，以生成ACRD总覆盖范围。 对各筛选结果进行融合处理，得到最终的总覆盖范围。 **数据集引用** 生物区域评估计划（2016）《HUN地表水建模总矿山覆盖范围v01》，生物区域评估衍生数据集，查阅于2018年6月22日，访问地址：http://data.bioregionalassessments.gov.au/dataset/b78597ba-4781-4b95-80c3-d6c11cb2e595。 **数据集前身** * **衍生自** [HUN地下水覆盖范围多边形v01](https://data.gov.au/data/dataset/c7672a9d-422e-425e-82ef-11afc5fb7ba6) * **衍生自** [BILO网格化气候数据：1900年至2012年逐年逐日气候数据](https://data.gov.au/data/dataset/7aaf0621-a0e5-4b01-9333-53ebcb1f1c14) * **衍生自** [HUN历史陆地卫星（Landsat）影像矿山覆盖范围v01](https://data.gov.au/data/dataset/28de7771-28f5-4d24-943f-0addea07c8c4) * **衍生自** [历史矿山覆盖范围DTIRIS HUN 20150707](https://data.gov.au/data/dataset/7b91b53c-2f09-4cd7-a38b-746446c06a72) * **衍生自** [用于时间序列分析的HUN矿山覆盖范围](https://data.gov.au/data/dataset/1e18f597-c8dd-4dae-b460-de9f5ebb1c6a) * **衍生自** [澳大利亚1981年至2012年年均气候数据](https://data.gov.au/data/dataset/02418c67-f8bb-48a8-88a3-2a5c6b485f78) * **衍生自** [HUN历史陆地卫星（Landsat）衍生矿山覆盖范围v01](https://data.gov.au/data/dataset/e852e582-d0e7-4543-ac70-feba694597c0) * **衍生自** [HUN地表水覆盖范围形状文件v01](https://data.gov.au/data/dataset/2a9520c8-1569-4e0e-8bd8-26e2c7b9e9e0) * **衍生自** [0.05×0.05分辨率格网及格网质心气候模型](https://data.gov.au/data/dataset/3df5188b-f027-4d51-99a8-45e2800f29c8)
