GLO subregion boundaries for Impact and Risk Analysis 20160712 v01

Abstract

This dataset includes the current boundary data required for the bioregional assessment impact analysis for the Gloucester subregion. These data are (1) the current Preliminary Assessment Extent (PAE), (2) the Analysis Extent (AE) and (3) the Analysis Domain Extent (ADE).

The PAE is defined and explained in the BA submethodology (1.3 Description of the water-dependent asset register) and, specifically for the Gloucester subregion in product 1.3 Water-dependent asset register for the Gloucester subregion. The Analysis Extent (AE) is defined as the geographic area that encompasses all the possible areas that may be reported as part of the impact analysis component of a bioregional assessment, specifically, the subregion boundary, the PAE and the relevant groundwater and surface water model domains. For Gloucester, the AE consists of the PAE boundary plus some minor extensions to include the alluvium groundwater model domain, particularly adjacent to the Duralie mine. The Analysis Domain Extent (ADE) is defined as the geographic area used for geoprocessing and data preparation purposes that encompasses the Analysis Extent plus additional areas sufficient to ensure all relevant data is included for the impact analysis component of a bioregional assessment. For Gloucester, at least an additional 1.5 km was added to the AE boundary and, in places further extensions were required to include all of the groundwater model domain.

All data are in the Australian Albers coordinate system (EPSG 3577).

Purpose

The purpose of this dataset is to provide the boundaries needed for the impact analysis component of the BA.

Dataset History

This dataset includes the current boundary data required for the bioregional assessment impact analysis for the Gloucester subregion. These data are (1) the current Preliminary Assessment Extent (PAE), (2) the Analysis Extent (AE) and (3) the Analysis Domain Extent (ADE). All data were transformed to the Australian Albers coordinate system (EPSG 3577).

The PAE is defined and explained in the BA submethodology (1.3 Description of the water-dependent asset register) and, specifically for the Gloucester subregion in product 1.3 Water-dependent asset register for the Gloucester subregion. For Gloucester, the original PAE contained a 'hole' in the southern end. For the purposes of the impact analysis, this 'hole' has been removed. Due to this change, it is possible that there may be water-related assets in the location of the 'hole' that were not included in the asset database and asset register. This should be noted in any assessment reports.

The Analysis Extent (AE) is defined as the geographic area that encompasses all the possible areas that may be reported as part of the impact analysis component of a bioregional assessment, specifically, the subregion boundary, the PAE and the relevant groundwater and surface water model domains. For Gloucester, the AE consists of the PAE boundary plus some minor extensions to include the alluvium groundwater model domain, particularly adjacent to the Duralie mine. Due to these extensions, it is possible that there may be water-related assets in the location of the extensions that were not included in the asset database and asset register. This should be noted in any assessment reports.

The Analysis Domain Extent (ADE) is defined as the geographic area used for geoprocessing and data preparation purposes that encompasses the Analysis Extent plus additional areas sufficient to ensure all relevant data is included for the impact analysis component of a bioregional assessment. For Gloucester, at least an additional 1.5 km was added to the AE boundary and, in places further extensions were required to include all of the groundwater model domain.
