| Data Quality | Lineage | CD boundaries are aligned to the PSMA digital topographic database used for ASGC 2006 boundary set (mid 2004 through early 2005). Higher level spatial units are aggregated from the CD level. |
| Positional Accuracy | The PSMA topographic database to which boundaries are aligned was captured at scales which vary from 1:4,000 in urban areas to 1:250,000 in remote areas |
| Attribute Accuracy | Geographical area codes & labels are 100 % validated to the 2006 edition codes & labels of the structures represented. (Reference is ABS cat no. 2905.0). |
| Logical Consistency | Spatial units are closed polygons. Polygons are attributed with codes & labels. Slivers/bow-ties may be present within or between spatial units.
These data include attribute records without spatial objects for administrative purposes.
It should be noted that some POAs, SEDs and IREGs cross state and territory borders. |
