DESCRIPTION
Abstract
3 These digital boundaries represent Mesh Blocks which are the smallest geographical unit for which ABS data will be output. Mesh Blocks will be integrated into the ABS's statistical geography for the 2011 Census. These Mesh Blocks are currently experimental and contain basic 2006 Census data (total usual resident population and dwelling count). Mesh Blocks are identified with a unique 11 digit code.

DATA QUALITY
Lineage
10 Mesh Blocks 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
11 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
12 Mesh Block codes & labels are fully validated.
Logical Consistency
13 Spatial units are closed polygons. These data include attribute records without spatial objects for administrative purposes.
Completeness
14 The 2006 Mesh Blocks are represented in their entirety.
