Digital boundary files

Australian Statistical Geography Standard (ASGS) Edition 3
Reference period
July 2021 - June 2026

Australian Statistical Geography Standard (ASGS) digital boundaries are available in either the OGC GeoPackage, or ESRI shapefile formats. These boundaries are also available in a Web Linked Dataset.

Digital boundaries are available in both the Geocentric Datum of Australia 2020 (GDA2020) and the Geocentric Datum of Australia 1994 (GDA94). GDA2020 was adopted as the new official national datum in 2017 and will be adopted gradually by organisations across Australia. The difference between GDA94 and GDA2020 on the ground is currently about 1.8 metres. Eventually, the ABS will phase out GDA94 boundaries.

Most GIS software automatically converts boundaries from GDA94 to GDA2020 and vice versa. The ABS uses a conformal only 7 point method for converting GDA94 boundaries to GDA2020. For more information about GDA2020, please refer to the Intergovernmental Committee on Surveying and Mapping or Geoscience Australia.

Metadata for digital boundary files

Digital boundaries for each level of the ASGS will be made available as each section of ASGS Edition 3 is published. The boundaries will be available in both GeoPackage and ESRI Shapefile format. Some basic metadata about each of the boundary files is listed below.

Main Structure and Greater Capital City Statistical Areas (GCCSAs)

Australian Statistical Geography Standard (ASGS) Edition 3

Date of publication: 20 July 2021
Presentation format: digital boundaries
Custodian: Australian Bureau of Statistics (ABS)

Description

The Main Structure and Greater Capital City Statistical Areas of ASGS Edition 3 consists of the following regions:

  • Mesh Block (MB)
  • Statistical Area Level 1 (SA1)
  • Statistical Area Level 2 (SA2)
  • Statistical Area Level 3 (SA3)
  • Statistical Area Level 4 (SA4)
  • Greater Capital City Statistical Areas (GCCSA)
  • State and Territory (S/T)
  • Australia (AUS)

Nomenclature

File names have the format <file type>_<2021>_<AUST> where:

  • <file type> represents the type of boundaries in each file
  • MB = Mesh Block
  • SA1 = Statistical Area Level 1
  • SA2 = Statistical Area Level 2
  • SA3 = Statistical Area Level 3
  • SA4 = Statistical Area Level 4
  • GCCSA = Greater Capital City Statistical Area
  • STE = State and Territory
  • AUS = Australia
  • <2021> represents 2021 the year of the Australian Statistical Geography Standard (ASGS) Edition 3
  • < AUST> indicates the data covers all of Australia

Within the files, the States and Territories are identified by unique one digit codes.

Date of effect: 20 July 2021

Dataset status

Progress: Completed dataset

Maintenance and update frequency: No further updates for these boundaries are planned. There will be a progressive release of the other regions that make up the ASGS until early 2023.

Access

Stored data format: Digital as separate files for each level of the Main Structure and GCCSA of ASGS Edition 3.

Available format: The digital boundary files are in GeoPackage and ESRI Shapefile (.shp) format.

Spatial representation type: Vector

Access constraints: Copyright Commonwealth of Australia administered by the ABS. Unless otherwise noted, content is licensed under a Creative Commons Attribution 4.0 International licence.

Datum:

  • Geocentric Datum of Australia 1994 (GDA94)
  • Geocentric Datum of Australia 2020 (GDA2020)

Projection: Geographic (i.e. latitudes and longitudes)
Geographic extent: Geographic Australia
Extent - geographic bounding box:
North bounding latitude: -8
South bounding latitude: -45
West bounding latitude: 96
East bounding latitude: 169

Data quality

Lineage: Mesh Block boundaries were created using various sources including the Geoscape digital datasets and ABS boundaries, zoning information from state planning agencies, and imagery.

Positional accuracy: Positional accuracy is an assessment of the closeness of the location of spatial objects in relation to their true positions on the earth's surface.
The positional accuracy includes:

  • a horizontal accuracy assessment
  • a vertical accuracy assessment

Positional accuracy for ABS boundaries is dependent on the accuracy of the features they have been aligned to.

ABS boundaries are aligned to layers supplied by Geoscape with an accuracy of +/-50 mm. Geoscape layers and their positional accuracy are as follows:

  • Transport and Topography: +/- 2 metres in urban areas and +/- 10 metres in rural and remote areas.
  • CadLite: +/- 2 metres in urban areas and +/- 10 metres in rural and remote areas.
  • Administrative Boundaries: Derived from the cadastre data from each Australian state and territory jurisdiction.
  • Greenspace and Hydrology: 90% of well-defined features are within 1mm (at plot scale) of their true position, for example 1:500 equates to +/- 0.5 metre and 1:25,000 equates to +/- 25 metres. Relative spatial accuracy of these themes reflects that of the jurisdictional source data. The accuracy is +/- 2 metres in urban areas and +/- 10 metres in rural and remote areas. No "shift" of data as a means of "cartographic enhancement" to facilitate presentation has been employed for any real world feature.
  • Precision: Boundary coordinates have been rounded to 8 decimal places, equivalent to 1.1132mm at the equator. All ABS boundaries have been generalised to 5cm with a 7.5cm shared boundary tolerance.
  • Attribute accuracy: All codes and labels for all levels within the ASGS Main Structure and GCCSAs are fully validated.
  • Logical consistency: Regions are closed polygons. Attribute records without spatial objects have been included in the data for administrative purposes.
  • Completeness: All levels of the Main Structure and GCCSAs within ASGS Edition 3 are represented.

XML metadata files

The compressed download files include geospatial metadata data for each region type in Extensible Markup Language (XML) format. The geospatial metadata conforms to International Organisation for Standardization (ISO) geospatial metadata standard, ISO 19115:2003, and the associated XML implementation schema specified by ISO 19139:2012.
