LIST Transport Segment data is a subset of the LIST Transport Segment data and comprises transport routes with highway status. The subset has been created to provide clarity on ownership of roads (Authority). Metadata for each line is linked to the Transport Segment layer through the Feature Metadata Pointer (FMP) attribute.

The majority of information for this data set was initially captured from a GPS survey on State Highways and Subsidiary Roads in 1998. Much of this data has since been updated by using as constructed drawings and ortho-rectified aerial imagery. Data is continually being revised and upgraded. Metadata for each line is linked to the Transport Segment layer through the Feature Metadata Pointer (FMP) attribute. Any errors should be reported to the Department of State Growth.

Position Accuracy: Horizontal accuracy is estimated at ± 5 metres for 95% of the data. The accuracies might not be achieved in areas of dense vegetation, rugged terrain or where satellite coverage is poor. Position Accuracy can be obtained from the Feature Metadata Pointer (FMP) for the transport segment that the LIST Transport layer is comprised of. Attribute Accuracy: The accuracy of the attribute information is estimated at 95%. Logical Consistency: All lines are labelled with a Unique Feature Identifier (UFI). This UFI is linked to a Feature Metadata Pointer (FMP) which contains the aerial photography date, horizontal accuracy and the metadata directory number. All data has been checked both visually and by automated processes for undershoots, overshoots and correct data attribution. Completeness: The LIST Transport Segment dataset is complete for Tasmania, excepting Macquarie Island.
