Lineage

The road centerlines have been generated from the topography theme using the ArcInfo 8.0.2 command CENTERLINE. Road intersections and other errors were manually edited/corrected in ArcEdit. The final version was opened, checked and attributed in ArcView 3.2 and saved as an ESRI shapefile.

Roads were only extended to form obvious intersections and no missing road sections were added (for consistency and due to the age of the orthophotography).

In December 2003 GA projected the data to UTM (WGS84) zone 47S using ArcView

Positional Accuracy

The road centrelines have a positional accuracy comparable to that of the road edges in the topography.

Attribute Accuracy Attribute descriptions appear to match the feature types as visible on the orthophotography (1987).
Logical Consistency This theme is a derivative of the infrastructure theme and thus all attributes are associated with this.
Completeness Incomplete. The original feature data.
