2.5 Vegetation

2.5.1 Cleared Lines

2.5.1.1 Example 1
Location of Example: 152°51'25" East, 25°19'22" South
Distinctive Characteristics:
  • In Figure 2.5.1.1a the Cleared Lines (created 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.
Regional Considerations:

2.5.1.2 Example 2
Location of Example: 141°50'04" East, 27°54'22" South
Distinctive Characteristics:
  • Figure 2.5.1.2 is a representation of Cleared Lines in a Remote Area (created for fire breaks, seismic monitoring, etc).
  • Cleared lines have numerous attributes that differ from roads:
    • They are generally straighter and can sometimes form a rectilinear pattern.
    • 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.
  • Cleared lines may also show signs of overgrowth if not accessed recently.

2.5.2 Cultivated Areas

2.5.2.1 Example 1
Location of Example: 152°17'51" East, 24°48'37" South
Distinctive Characteristics:
  • Orchards can be identified by their orderly planting and contrast with the surrounding vegetation growth.
  • Orchards have farm infrastructure associated with them.
  • No significant vehicle tracks are generally visible through this area.
Regional Considerations:
  • Orchards visibility on imagery vary depending on the season. eg. Apple trees in Autumn.

2.5.2.2 Example 2
Location of Example: 152°36'50" East, 25°22'29" South
Distinctive Characteristics:
  • Pine plantation can be distinguished by the tightly compacted rows of trees.
  • Figure 2.5.4.1b shows both the newly planted rows, against the mature grown area, which is shown in dark green.
Regional Considerations:

2.5.3 Cotton Gins

2.5.3.1 Example 1
Location of Example: 149°33'42" East, 28°37'13" South
Distinctive Characteristics:
  • The Cotton Gin facility has distinctive rectangular bundles of cotton during harvesting that are not topographic features and should not be captured.
  • Related infrastructure such as Buildings and Canals can be captured.
Regional Considerations:

2.5.3.2 Example 2
Location of Example: 149°35'22" East, 29°26'22" South
Distinctive Characteristics:
  • The Cotton Gin facility has distinctive rectangular bundles of cotton during harvesting that are not topographic features and should not be captured.
  • Related infrastructure such as Buildings and Canals can be captured.
Regional Considerations:

2.5.3.3 Example 3
Location of Example:
Distinctive Characteristics:
  • Regular shaped Bundles of Cotton aligned on Cotton Gin.
  • Note the tarpaulin covering the bundles. These covers cause bright white signatures on multispectral imagery.
Regional Considerations:

2.5.4 Windbreaks

2.5.4.1 Example 1
Location of Example: 149°20'42" East, 28°31'07" South
Distinctive Characteristics:
  • Windbreaks are located within paddocks. Windbreaks are not remnant vegetation along road corridors.
  • Remnant vegetation along road corridors must not be depicted as Windbreaks.
Regional Considerations:
  • Windbreaks typically occur in relatively flat, open regions of agricultural production where strong prevailing winds can have a destructive impact.

2.5.4.2 Example 2
Location of Example: 149°20'42" East, 28°31'07" South
Distinctive Characteristics:
  • Windbreaks are located within paddocks. Winbreaks are not remnant vegetation along road corridors.
  • Remnant vegetation along road corridors must not be depicted as Windbreaks.
Regional Considerations:
  • Windbreaks typically occur in relatively flat, open regions of agricultural production where strong prevailing winds can have a destructive impact.
