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.
Approved boundaries of the bioregions and subregions (version 5) for defining the reporting regions for bioregional assessments of impacts of coal seam gas and coal mining development on water resources.
This is identical to Bioregional_Assessment_areas_v04 except that the attribute tables include areas (both sq. km and ha) based on the GDA 1994 Australia Albers projection. A spreadsheet version of the attribute table is also provided for the benefit of non ArcGIS users.
Provides authoritative boundaries for defining bioregions and subregions to be reported on for the Bioregional Assessments and tabulation of Bioregion and subregion areas.
This dataset contains two spatial shapefiles: "ba_bioregion_alb_gda94_v05.shp" and "ba_subregion_alb_gda94_v05.shp".
The shapefiles are copies of the previous versions (Bioregional Assessment Areas v04), with the following changes.
Two fields have been added to each of the shapefiles' attribute tables.
"albers_km2" and "albers_ha" which list the the bioregion/subregion areas in square kilometres and hectares respectively.
The polygonal areas are calculated in ArcGIS and are based on the GDA_1994_Australia_Albers projection. Parameters as follows:
Projected Coordinate System: GDA_1994_Australia_Albers
Projection: Albers
False_Easting: 0.00000000
False_Northing: 0.00000000
Central_Meridian: 132.00000000
Standard_Parallel_1: -18.00000000
Standard_Parallel_2: -36.00000000
Latitude_Of_Origin: 0.00000000
Linear Unit: Meter
Geographic Coordinate System: GCS_GDA_1994
Datum: D_GDA_1994
Prime Meridian: Greenwich
Angular Unit: Degree
It should be noted that area calculations using a different projection (eg UTM or MGA) may yield slightly different areas to those published in this dataset.
Version 5 of this dataset also includes Excel spreadsheet versions of each shapefiles' attrubute table, to enable non ArcGIS users to access the bioregion/subregion area information.
