Description

Abstract:

This edition of theAustralian Statistical Geography Standard (ASGS) Volume 3 - Non-ABS Structures(cat no. 1270.0.55.003), is the 2020 update of the ASGS Volume 3 that was published in 2019. It contains the names, codes and digital boundaries for regions that have changed since the 2019 release.

The digital boundaries for this update represent the Non-ABS Structures, comprising of:

    • Local Government Area (LGA)
    • State Electoral Division (SED)

File Nomenclature:


File names have the format <file type>_<2020>_<AUST> where:
< file type> represents the type of boundaries in each file
LGA = Local Government Area
SED = State Electoral Division
< 2020> represents 2020 the year of the Australian Statistical Geography Standard (ASGS) Edition
< AUST> indicates the data that covers all of Australia as defined in ASGS Volume 1.

Where applicable States and Territories are identified by unique one digit codes, as listed below:

Dataset Status

Progress:
Complete

Maintenance and Update Frequency:


As the Non ABS Structures represent regions that are subject to ongoing change, the ABS will release a revised publication for ASGS Non ABS Structures in July each year. The individual structures will only be updated where significant change has occurred in the past year.


Access

Stored Data 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 2.5 Australia licence.

Datum:


Geocentric Datum of Australia 1994 (GDA94)

The digital boundary files have the datum specified as 116 (GDA94). Users of MapInfo 6.0 or later are able to load data sets based on GDA94 directly, without transformation. Earlier versions of MapInfo cannot interpret GDA94 correctly and there may be alignment problems between data sets based on this datum and other earlier datums.

Projection:


Geographical (i.e. Latitudes and Longitudes)

Geographic Extent:


Geographic Australia.


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 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
    Relative spatial accuracy of these themes reflects that of the jurisdictional source data. Generally the accuracy is +/- 2 metres in urban areas and +/- 10 metres in rural and remote areas.


Attribute Accuracy:


All codes and labels for all structures within the ASGS 2020 Non ABS Structures are fully validated.


Logical Consistency:


Spatial units are closed polygons. Attribute records without spatial objects have been included in the data for administrative purposes.
