NTDB & NTMS Specifications (250K & 100K)
Updated: 1 December 2007

2.2.1 Roads Surface - Sealed/Unsealed

2.2.1.3 Example 3
Location of Example: 152°44'40" East, 25°18'31" South
Distinctive Characteristics:
  • In Figure 2.2.1.3a the grey colour depicts the sealed road compared with the lighter grey/white colour that represents the unsealed roads.
  • The sealed road is also much better formed and narrower compared with the loosely formed wide unsealed roads, created by grading.
  • In Figure 2.2.1.3b the darker blue/grey signature depicts the sealed road compared with the paler blue/white of the unsealed roads.
Regional Considerations:
  • In Peri-Urban areas roads frequently change from sealed to unsealed.
