2.2.2 Roads Vs Linear Features

2.2.2.1 Example 1

Location of Example: 152o51'25" East, 25o19'22" South
Distinctive Characteristics:
  • In Figure 2.2.1.1a the Cleared Lines (created for Powerlines, pipelines, fire breaks, seismic monitoring, etc) have numerous attributes that differ to roads:
    • They are generally wider and straighter.
    • They have no pavement or bitumen.
    • There are generally no roads diverging off them.
    • There are generally no access points along these lines to buildings, dwellings or other infrastructure.
  • In Figure 2.2.1.1b the Cleared Line stands out as a stark white, wide line.
Regional Considerations:
