DESCRIPTION


Abstract:


The Australian Statistical Geography Standard (ASGS) is a hierarchical classification system of geographical regions and consists of a number of interrelated 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 July 2016. It provides a common framework of statistical geography and enables the production of statistics which are comparable and can be spatially integrated.

This product, Australian Statistical Geography Standard (ASGS) Volume 2 - Indigenous Structure (cat no. 1270.0.55.002), is the second in a series of Volumes that detail the various structures and regions of the ASGS. Its purpose is to outline the conceptual basis for the design of the Indigenous Structure. This product contains several elements including the manual, region names and codes and the digital boundaries.

The digital boundaries for Volume 2 of the ASGS represent the Indigenous Structure, comprising;

  • Indigenous Locations (ILOC)
  • Indigenous Areas (IARE)
  • Indigenous Regions (IREG)


File Nomenclature:


File names have the format <file type>_<2016>_<AUST> where:
<file type> represents the type of boundaries in each file
ILOC = Indigenous Location
IARE = Indigenous Area
IREG = Indigenous 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 the ASGS Volume 1.

Within the files, the States and Territories are identified by unique one digit codes, as listed below:

State and Territory Codes and Names

DATASET STATUS


Progress:
Completed dataset

Maintenance and Update Frequency:

No further updates for these boundaries planned. There will be a progressive release of the other regions that make up the ASGS until late 2018 (ASGS Volumes 4 and 5). The ASGS will be revised in 2021.

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 and ABS SLA 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
    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.


Attribute Accuracy:


All codes and labels for the ASGS 2016 Indigenous Structure 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 2016 ASGS Indigenous Structure are represented.
