HUN Analysis boundaries 20170106 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 dataset includes the current boundary data required for the bioregional assessment impact analysis for the Hunter (HUN) subregion. These data are (1) the current Preliminary Assessment Extent (PAE) which for Hunter is the current subregion boundary, (2) the Analysis Extent (AE) and (3) and the Analysis Domain Extent (AD). 



The PAE is defined and explained in the BA submethodology (1.3 Description of the water-dependent asset register) and, specifically for the HUN  subregion in product 1.3 Water-dependent asset register for the HUN 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 and the PAE. The Analysis Domain extent (AD) 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 HUN, the ADE had at least an additional 20 km geographic buffer added to the AE boundary.



All data are in the Australian Albers coordinate system (EPSG 3577).

## **Purpose** 

The purpose of the various boundary polygons are to assist in the efficient spatial analysis of the impact of coal resource development in the Hunter subregion.

## **Dataset History** 

This dataset includes the current boundary data required for the bioregional assessment impact analysis for the Hunter (HUN) subregion. These data are (1) the current Preliminary Assessment Extent (PAE) which for Hunter is the current subregion boundary, (2) the Analysis Extent (AE) and (3) and the Analysis Domain Extent (AD). 



The PAE is defined and explained in the BA submethodology (1.3 Description of the water-dependent asset register) and, specifically for the HUN subregion in product 1.3 Water-dependent asset register for the NAM 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 and the PAE. The Analysis Domain extent (AD) 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 HUN, the ADE had at least an additional 20 km geographic buffer added to the AE boundary.
