METADATA FOR DIGITAL BOUNDARY FILES - LABOUR FORCE REGIONS 2007
The table shows file type, file name, spatial unit field and the data type.
File Type: Labour Force Region (LFR)
File Name (s): LFR_2007_AUST
Date of Effect: July 2009
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.
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.

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.
Geographical (i.e. Latitudes and Longitudes)
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 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:
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:
All codes and labels for the Labour Force Region 2007 structure are fully validated.
Spatial units are closed polygons. Attribute records without spatial objects have been included in the data for administrative purposes.
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.
