METADATA FOR DIGITAL BOUNDARY FILES - ASGS NON ABS STRUCTURES
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
All tables show file type, file name, spatial unit field and the data type.

Date of Effect: 13 September 2016
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.
Stored Data Format:
Digital as separate files for each level of the Indigenous Structure of the ASGS 2016.
The digital boundary files are in MapInfo TAB format (.TAB), MapInfo Interchange Format (.MID .MIF), Geopackage and ESRI Shapefile (.shp) format.
Spatial Representation Type:

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)
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 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 all structures within the ASGS 2016 Non ABS Structures are fully validated.
Spatial units are closed polygons. Attribute records without spatial objects have been included in the data for administrative purposes.
All structures within the 2016 ASGS Non ABS Structures are represented.
