METADATA FOR DIGITAL BOUNDARY FILES - LABOUR FORCE REGIONS 2007

TITLE

Information Paper: Regional Labour Force Statistics
(cat. no. 6262.0)

Data Currency:
July 2009

Presentation Format:
Digital boundaries


CUSTODIAN


Custodian:
Australian Bureau of Statistics


DESCRIPTION


Abstract:


These boundaries reflect PDF maps that were released in conjunction with the 3 July 2009 issue of Australian Labour Market Statistics (cat. no. 6105.0). They represent the new Labour Force Sample design which was implemented between November 2007 and June 2008. The Labour Force boundaries are aggregations of Statistical Local Areas (SLAs) from the 2006 edition of the Australian Standard Geographical Classification (ASGC).


File Nomenclature:

File names have the format <file type>_<2007>_<AUST> where:

<file type> represents the type of boundaries in each file
LFR = Labour Force Region

<2007> represents 2007 the year of the new Labour Force Sample design

<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

Code State or Territory

1 New South Wales
2 Victoria
3 Queensland
4 South Australia
5 Western Australia
6 Tasmania
7 Northern Territory
8 Australian Capital Territory
9 Other Territories

DATASET STATUS


Progress:
Completed dataset

Maintenance and Update Frequency:
There are no current plans for updates to these ASGC-based boundaries. In future ASGS Statistical Areas Level 4 will be used as labour force geographic regions. Information Paper: Regional Labour Force Statistics (cat. no. 6262.0) describes these changes.

ACCESS


Stored Data Format:


The digital boundary files are in MapInfo Interchange Format (.MID .MIF) and ESRI Shapefile (.shp) format.

MapInfo Interchange Format can be imported directly into MapInfo and other common Geographic Information Systems (GIS) or desktop mapping packages. The .MID .MIF files are text format and can be edited and manipulated for import to less common GIS and CAD systems.

The .MID .MIF files cannot be used directly with viewing tools such as MapInfo ProViewer.

Access Constraints:


Copyright Commonwealth of Australia administered by the ABS.

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:


Collection Districts (CDs) are the building blocks of the SLA regions used in turn to build Labour Force Regions. CD boundaries were created using digital topographic datasets from the PSMA.


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 Labour Force Region 2007 structure 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 regions of the Labour Force Regions 2007 are represented. For completeness the Other Territories (Jervis Bay Territory, Christmas Island, Cocos (Keeling) Islands) are included as boundaries. Other Territories are not included in Labour Force samples.
