The 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.
The 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.
Used only for report map display and area calculation purposes
Polygons from the source dataset were selected as follows:
for the total surface water modelling baseline footprint polygons were selected where SW_BL - 'yes'.
for the CRDP footprint polygons were selected where any of SW_BL, SW_CRDP or SW_ACRD = "yes"
The Baseline total footprint was removed (ERASE command) from the CRDP total footprint to create a ACRD total footprint.
Respective selections were dissolved to obtain overall total footprints.
