HUN SW GW Mine Footprints for IMIA 20170303 v03

Abstract

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.

This contains shapefiles of mine footprint used for Hunter surface water and ground water modelling as well as identifying FUTURE (baseline/ACRD) and MINETYPE (open cut/underground).

Note: 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.

Dataset History

For 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 for each unique mine name (TITLE).

Some mine polygons had CRDP shapes rather than ACRD shapes. These had their resepetive baseline areas clipped out of the CRDP area to create an ACRD polygon. Thus there are no explicit CRDP polygons in this dataset. CRDP areas can be inferred by considering the baseline + ACRD area for each mine.
