DESCRIPTION

Abstract:

The Australian Statistical Geography Standard (ASGS) brings together in one framework all of the regions which the ABS and many others organisations use to collect, release and analyse geographically classified statistics. The ASGS ensures that these statistics are comparable and geospatially integrated and provides users with an coherent set of standard regions so that they can access, visualise, analyse and understand statistics. The 2016 ASGS will be used for the 2016 Census of Population and Housing and progressively introduced into other ABS data collections. The ABS encourages the use of the ASGS by other organisations to improve the comparability and usefulness of statistics generally, and in analysis and visualisation of statistical and other data.

This publication, Australian Statistical Geography Standard (ASGS) Volume 1 - Main Structure and Greater Capital City Statistical Areas (cat no. 1270.0.55.001), deals with the ASGS Main Structure (Statistical Areas Level 1 - 4) and the Greater Capital City Statistical Areas (GCCSA). It outlines the conceptual basis of the ASGS Main Structure and the GCCSAs and their relationships to each other. This product contains several elements including the ASGS manual, allocation tables, correspondences and the digital boundaries current for the ASGS Edition 2016 (date of effect 1 July 2016).

The digital boundaries for Volume 1 of the ASGS are the region types for the main structure and the GCCSAs. These region types are:

  • 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).

File Nomenclature:

Mesh Block file names have the format <file type>_<2016>_<STATE> where:
<file type> represents the type of boundaries in each file
MB = Mesh Block
<2016> represents 2016 the year of the Australian Statistical Geography Standard (ASGS) Edition
< STATE> indicates the data covers a State as defined in the ASGS manual

Other file names have the format <file type>_<2016>_<AUST> where:
<file type> represents the type of boundaries in each file
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
<2016> represents 2016 the year of the Australian Statistical Geography Standard (ASGS) Edition
< AUST> indicates the data covers all of Australia as defined in the ASGS manual

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

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 PSMA 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 the 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 a number of layers supplied by PSMA with an accuracy of +/-50 mm. PSMA layers and their positional accuracy are as follows:
  • Transport and Topography
+/- 2 meters in urban areas and +/- 10 meters in rural and remote areas
  • CadLite
+/- 2 meters in urban areas and +/- 10 meters 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, eg 1:500 equates to +/- 0.5metre 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.

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 the 2016 ASGS are represented.
