DESCRIPTION

Abstract:


The Australian Statistical Geography Standard (ASGS) is a hierarchy of geographic structures designed to meet the specific requirements of ABS statistical outputs as well as being able to represent commonly used Non ABS geographic structures. The ASGS brings all the regions for which the Australian Bureau of Statistics (ABS) publishes statistics within the one framework and will be used by the ABS for the collection and dissemination of geographically classified statistics from the 1 July 2016.

This product, Australian Statistical Geography Standard (ASGS) Volume 3 - Non ABS Structures (cat no. 1270.0.55.003), is the third in a series of five volumes that describe the structures that make up the ASGS. Its purpose is to outline the conceptual basis for the design of the Non ABS Structures. This product contains several elements including the manual, region names and codes and the digital boundaries.

The digital boundaries for Volume 3 of the ASGS represent the Non ABS Structures, comprising of:

  • Local Government Area (LGA)
  • Postal Area (POA)
  • State Suburb (SSC)
  • Commonwealth Electoral Division (CED)
  • State Electoral Division (SED)
  • Natural Resource Management Region (NRMR)
  • Australian Drainage Division (ADD)
  • Tourism Region (TR).

File Nomenclature:


File names have the format <file type>_<2016>_<AUST> where:
<file type> represents the type of boundaries in each file
LGA = Local Government Area
POA = Postal Area
SSC = State Suburb
CED = Commonwealth Electoral Division
SED = State Electoral Division
NRMR = Natural Resource Management Region
ADD = Australian Drainage Division
TR = Tourism Region
<2016> represents 2016 the year of the Australian Statistical Geography Standard (ASGS) Edition

< AUST> indicates the data 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:
State and Territory Codes and Names

DATA CURRENCY

Date of Effect:
13 September 2016


DATASET STATUS

Progress:
Completed dataset

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:


Digital as separate files for each level of the Indigenous Structure of the ASGS 2016.

Available Format:

The digital boundary files are in MapInfo TAB format (.TAB), MapInfo Interchange Format (.MID .MIF), 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 Blocks are the building blocks of the ASGS regions. Mesh Block boundaries were created using various sources including the PSMA digital topographic datasets, ABS SLA boundaries and 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
    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 2016 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.


Completeness:


All structures within the 2016 ASGS Non ABS Structures are represented.
